2. Show HN: DBOS TypeScript – Lightweight Durable Execution Built on Postgres

Show HN: DBOS TypeScript – Lightweight Durable Execution Built on Postgres - Project Screenshot

URL: https://github.com/dbos-inc/dbos-transact-ts

Author: KraftyOne

Description: Hi HN - Peter from DBOS here with my co-founder Qian (qianl_cs)

Today we want to share our TypeScript library for lightweight durable execution. We’ve been working on it since last year and recently released v2.0 with a ton of new features and major API overhaul.

https://github.com/dbos-inc/dbos-transact-ts

Durable execution means persisting the execution state of your program while it runs, so if it is ever interrupted or crashes, it automatically resumes from where it left off.

Durable execution is useful for a lot of things:

- Orchestrating long-running or business-critical workflows so they seamlessly recover from any failure.

- Running reliable background jobs with no timeouts.

- Processing incoming events (e.g. from Kafka) exactly once

- Running a fault-tolerant distributed task queue

- Running a reliable cron scheduler

- Operating an AI agent, or anything that connects to an unreliable or non-deterministic API.

What’s unique about DBOS’s take on durable execution (compared to, say, Temporal) is that it’s implemented in a lightweight library that’s totally backed by Postgres. All you have to do to use DBOS is “npm install” it and annotate your program with decorators. The decorators store your program’s execution state in Postgres as it runs and recover it if it crashes. There are no other dependencies you have to manage, no separate workflow server–just your program and Postgres.

One big advantage of this approach is that you can add DBOS to ANY TypeScript application–it’s just a library. For example, you can use DBOS to add reliable background jobs or cron scheduling or queues to your Next.js app with no external dependencies except Postgres.

Also, because it’s all in Postgres, you get all the tooling you’re familiar with: backups, GUIs, CLI tools–it all just works.

Want to try DBOS out? Initialize a starter app with:

    npx @dbos-inc/create -t dbos-node-starter
Then build and start your app with:

    npm install
    npm run build
    npm run start
Also check out the docs: https://docs.dbos.dev/

We'd love to hear what you think! We’ll be in the comments for the rest of the day to answer any questions you may have.

Show HN: Skyvern 2.0 – open-source AI Browser Agent scoring 85.8% on WebVoyager - Project Screenshot

URL: https://eval.skyvern.com/

Author: suchintan

Description: Hey HN,

We’re Suchintan and Shu from Skyvern (https://www.skyvern.com). We’re building an open source AI Agent that can browse the web and take actions. Our open source repo can be found at https://github.com/Skyvern-AI/Skyvern.

We’ve re-built Skyvern with a Planner-Actor-Validator agent architecture and achieved 85.8% state of the art (SOTA) on the WebVoyager Benchmark. You can see the results for yourself here: https://eval.skyvern.com/

For reference, here were the previous SOTA results: 83.5% - Google Mariner (https://deepmind.google/technologies/project-mariner/) 73.1% - AgentE (https://arxiv.org/html/2407.13032v1) 67.0% - HCompany (https://www.hcompany.ai/blog/a-research-update) 59.1% - WebVoyager (https://arxiv.org/html/2401.13919v4) 52.6% - WILBUR (https://arxiv.org/html/2404.05902v1) 52.0% - Claude Computer Use (https://docs.anthropic.com/en/docs/build-with-claude/compute...)

Achieving this SOTA result required expanding Skyvern’s original architecture. Skyvern 1.0 involved a single prompt operating in a loop both making decisions and taking actions on a website. This approach was a good starting point, but scored ~45% on the WebVoyager benchmark because it had insufficient memory of previous actions and could not do complex reasoning.

We re-built this all using a Planner-Actor-Validator agent architecture:

  1. Planner - Decides that goals to accomplish on a website, and maintains a working memory of the overall goal and progress towards it
  2. Actor - Given a narrowly scoped goal, executes the goal on the website, reporting back
  3. Validator - Asserts whether the goal was successfully achieved and passes feedback back to the Actor + Planner

    We ran the benchmark on Skyvern cloud to test Skyvern 2.0 in a real-world environment – autonomously navigating the web in a remotely hosted browser without any human involvement.

    To keep with our open source mission, we decided to publish benchmark, modifications, and final results for anyone to review. This is important because we’re seeing an increasing trend of companies publishing their benchmarks with no way to access the results, so we’ve decided to make everything public.

    [1] Eval Dataset: https://github.com/Skyvern-AI/skyvern/tree/main/evaluation/d... [2] Modifications: https://github.com/Skyvern-AI/skyvern/pull/1576/commits/60dc... [3] Each run (incl prompts + responses) can be inspected here: https://eval.skyvern.com/

    The full report (incl an architecture diagram) can be found here: https://blog.skyvern.com/skyvern-2-0-state-of-the-art-web-na...

    If you’d like to give Skyvern a try, you can grab the open source version (https://github.com/Skyvern-AI/Skyvern) or the cloud version (https://app.skyvern.com/) and give it a go and share any feedback with us. We look forward to any and all of your comments!

Description: Hi there, I'm a freelance software developer who started that project some time ago.

I like to download videos from social media platforms like X (f.k.a Twitter) or Instagram. To do so, one normally visits one of the many download service websites, which are often broken, slow or full of ads.

So I decided to develop Squidlr, a website that allows you to comfortable download any video from social media sites. Fast, reliable and without any ads. And open source: https://github.com/rgueldenpfennig/Squidlr

Currently I support:

Twitter / X

Instagram

Facebook

TikTok

LinkedIn

In my free time I try to implement the support of additional video platforms.

Hope you may find it useful and enjoy!

Show HN: Data for AI and AI for Data - Project Screenshot

URL: https://www.opendatabay.com/

Author: ibnzUK

Description: Hey all,

We’ve applied to YC three times and got rejected each time. we’ll get there eventually! The main reasons for rejection were: being a solo founder (no co-founder), having no team, an MVP that wasn’t ready, or no traction in place.

--- My expertise lies in building software products for startups, unicorn companies, and even governments.

Throughout my years in software, I’ve had plenty of exposure to data products. I’ve faced recurring challenges like the lack of data, uncertainty around data handling, or even generating too much data and not knowing how to best utilize it to generate revenue. Many times, I turned to data marketplaces, but my experience with them was nightmare-ish and frustrating.

Every time I tried to use data marketplace, I was redirected to a data vendor. This meant spending 7–14 days on phone calls or emails, trying to explain my data needs, only to hear responses like, “Let me talk to data supplier and see if we can produce this dataset.” On top of that, navigating the top data marketplaces felt like you needed a master’s degree. Tasks like to create an account or view data listings and samples were always behind "Contact Us" walls.

In one of my previous startups, I built a data storage solution and spent an insane amount of time trying to sell it to B2B businesses. Most of my calls ended with, “Cool stuff, but this isn’t the problem we have.” From there, conversations often shifted toward data monetization and acquisition, with companies describing the same pain points and challenges they had with top-tier data marketplaces. That’s when I realized it wasn’t just me—the actual problem was much larger than it appeared.

I decided to continue as a solo founder and managed to attract 13 experienced professionals to the team. Together, we’ve built Opendatabay, an AI-powered data marketplace that makes data discovery, listing, and access as simple as shopping on Amazon.

The product is live, we are getting traction, and I’d love to hear your thoughts on its feel, look, and message we trying to deliver.

• Would you say it’s easy to use? • Do you understand what we do? • What, in your opinion, is missing?

I appreciate your feedback! Thanks, Justin (Founder)

Author: jonnylegs

Description: We’re trying to create a Financial Jarvis.

Think Excel meets decision trees - but in the Multiverse.

Here’s the thesis.

No one in their right mind would trust an LLM to drive a bunch of time-series financial calculations, years out into the future, of any real complexity. Simply too many variables, dependencies, nested calculations.

Plus their job would be on the line if it was incorrect.

Spreadsheets work - sort of - but they lack context. Each cell is just a number - no true metadata. And you can only really generate one scenario at a time.

You have outputs - but limited insights into the when, the what and the why of those outputs. At its core, spreadsheets are not designed with TIME as their primary axis.

To make this work - to provide operational context to a model - you need a different, repeatable data structure for defining time series financial calculations and the business logic. You need to be able to see each calculation and validate the inputs to trust the outputs.

whatifi is a visual, financial and strategic modeling framework that uses GPT and a node-based architecture to help you build (and audit) complex “what-if” scenarios without drowning in spreadsheets.

URL: https://triplit.com

Author: glezer

Description: My partner and I built a daily word game that has elements of the Mini Crossword, Wordle, and Spelling Bee, with some twists all its own.

I’ve been fairly obsessed with the New York Times crossword puzzle ever since I saw the documentary Wordplay about 12 years ago. I started with Mondays and gradually made my way up to Saturdays, and when I began to appreciate the puzzles as aesthetic objects worthy of appreciation and criticism (rather than just a slog to survive and then brag about), I began to wonder what it would be like to create puzzles. But making full crossword puzzles was always very daunting to me.

Luckily, my partner got an idea for a new word game while on vacation in Italy over-caffeinated on espresso, and boom! Triplit was born.

We feel that after the smashing success of Wordle, the time is ripe for a new quick daily word game. To us, Triplit combines the playful, at times cryptic clueing of crosswords with the mental manipulation of Spelling Bee and the feedback and scoring system of Wordle. It also introduces the concept of random clue order, so unlike a crossword you don’t know which clue applies to which answer. And Triplit also has multiple difficulty level settings to make it fun for a variety of players.

It has been so fun to build and iterate on! We have more features and improvements planned. We hope you enjoy playing, and would love to hear your feedback. And yes, we know there is a Triplit database, and we mean no disrespect to them :)

34. Show HN: Random Positive Reward App for iPhone

Show HN: Random Positive Reward App for iPhone - Project Screenshot

URL: https://apps.apple.com/us/app/tantaluspath/id6504832898

Author: cheepin

Description: I built an iPhone app that is now available in the App Store. Its purpose is to make it easy and effective to use intermittent positive reinforcement as a motivation tool - the psychological phenomenon behind doom-scrolling, gambling, and animal training, now finally purposed for your benefit. It provides the tools to manage the little treats your brain needs to move in the right direction, combined with gamification designed to support your journey and encourage healthy usage.

This is the outgrowth of a “scratch your own itch” project when I learned about how variable reward schedules and wanted to be able to use it to break through times of lower motivation. While simpler alternatives like rolling a (virtual) d20 worked to prove the concept, there was a lot of room for improvement. There’s a system for dynamically weighting outcomes inspired by how RNG-heavy video games avoid big streaks of wins/losses. The other big idea was building anticipation into the app itself in the form of gamification so even if your rewards themselves aren’t really getting you into the right headspace at some time, there’s something to work towards in-app to add an extra boost.

SwiftUI for presentation, Rust for business logic in case it ever pencils out business-wise to port to another platform. If I was doing it again starting today, I would probably do React Native for the UI, but the integration story with Rust was pretty weak when I was evaluating options (they work together well enough now, and I have another project combining them, but not able to justify a UI rewrite yet).

CTA: this is a niche product in a (currently) non-existent market category. I’m starving for feedback, so if you have opinions about the app or even just the problem space, please let me know (comments here, App Support link from App Store, or messages to TantalusPath on social media), and I’ll eat it up!

Show HN: GreenReguAI, the platform to simplify renewable energy compliance - Project Screenshot

URL: https://greenreguai.com/

Author: alessandrorossi

Description: Hi everyone, it's Alessandro here, and this is my first post on HN wuhuuuu :D

Anyways, I'm writing here because I wanted to get your constructive feedback on a project I recently developed, GreenReguAI (website: https://greenreguai.com/, video presentation: https://www.youtube.com/watch?v=0CTiVbwfIfo).

To give you a bit of context, I've got a background in Energy Engineering, and I worked a couple of years in a German company that builds large-scale photovoltaic and storage plants around the world. During my time at this firm, I was always baffled by how inefficient the process of regulatory compliance was. Basically, when you need to build a plant of this scale somewhere, you need to check loads of local laws to ensure that the project you want to build respects all of them.

This shouldn't be too hard to do theoretically, because these kinds of plants have been built for a long time, so the process should be pretty standardized, right?

Well, it should, but it's not that easy, at least not in Europe (and I suppose also in other parts of the world). It turns out that despite being one of the continents more favorable to renewables, Europe has quite fragmented legislation, and when one wants to build such a plant, they get lost in a jungle of ugly, hard-to-navigate websites that seem to have been developed in the 00s and never updated, multiple sources of truth with answers hidden in a small paragraph contained in a document of hundreds of pages, and all of this in a context that changes with a non-negligible frequency, because regulation evolves over time. I know this because once I had to make such an analysis for a storage plant in Poland, and it sucked.

Therefore, I thought that with the new technological development, this issue could, if not be completely solved, at least be made better.

GreenReguAI is atm a RAG connected to a commercial LLM and a database where many documents relevant to this context are stored, processed, divided into chunks, and embedded. The differentiating factor is that for each chunk I save a few metadata, including which document, page, and position in the page the chunk comes from. This enables the creation of a quite detailed 'source verification' feature that, in 1-click, enables the user to verify where each part of the answer provided by the AI Assistant comes from, even accessing the exact position in the original document. This feature is not like the ones of Perplexity, ChatGPT, or other similar products, which in their answers reference a certain source, but that's it, you need to navigate the source by yourself to find where exactly the info on which the answer is based is contained. In GreenReguAI, when you click on the source of the answer, you get redirected to the exact place where the info is, which is something essential when you need to work with super boring legal documents that are sooooo long.

If there is enough interest in this product, I'm already planning some improvements:

1) Make the RAG more 'agentic,' so that instead of a one-shot approach, the RAG agent can perform multiple queries and research, which should improve the quality of the answers.

2) Add a 'Sources Scouting Agent' that is connected to a few websites that publish the official sources we are looking for (like websites of governments, international agencies, and legislative entities) and automatically downloads the new ones relevant to this context once they are made available.

This is overall the idea, I would love to hear what you think about it <3

Show HN: WasmBots – A WebAssembly-powered programming game - Project Screenshot

URL: https://shaneliesegang.com/projects/wasmbots/

Author: sjml

Description: I've been working on a browser-based programming game where you write bots to explore procedurally generated dungeons in any WebAssembly-compatible language. It's like a minimalist roguelike where your character's brain is a program you write. There are pre-made libraries for C, Rust, Zig, Go, and AssemblyScript.

The game mechanics are intentionally simple for now, but the challenge comes from building up your bot's understanding of the world from limited local information. Your code needs to handle mapping, pathfinding, and strategy while dealing with monsters and potentially hostile other players.

Some interesting technical bits:

* Pure WebAssembly modules with no JavaScript dependencies (not even using wasm-bindgen for Rust)

* Cross-language development with native debugging support via language-specific trainer builds

* Custom messaging protocol implemented across the five example languages using code generation

The project started as a way for me to poke around WebAssembly, especially exploring its potential as a universal plug-in language. There were a lot of yaks to be shaved as I went, though, and I ended up also learning a bunch about various build systems, roguelike exploration mechanics, procedural generation, etc. It's been a fun experience so far and I feel like it's hit a nice point (decently polished presentation of bots exploring the dungeon) before I start the next phase of adding actual game mechanics.

Intro Video: <https://www.youtube.com/watch?v=DGkkTYJrflI>

Deployed site: <https://shaneliesegang.com/projects/wasmbots>

Auto-built: <https://sjml.github.io/wasmbots/>

Source (Monorepo): <https://github.com/sjml/wasmbots>

The whole thing so far has been a one-person show, and I was often learning bits of tech as I was building with them, so feedback (technical or otherwise) is very welcome.

Description: Hi Hacker News,

After 2 years of hard work, I’m excited to share something I’ve been building — a messaging app designed for people like me who forget easily, get distracted (hello, ADHD!), or have packed schedules.

The problem I wanted to solve is simple: not all messages are equally important, but most messaging apps treat them the same. So, I created a tool to help you focus on the messages that truly matter, whether they’re from family, friends, or work.

I’d love for you to check it out and share your feedback — it means everything as I work to make this even better.

Show HN: A privacy-first structured journaling app for personal values discovery - Project Screenshot

URL: https://www.clearlyhq.com

Author: didgeoridoo

Description: Hi HN!

I've spent the last year of nights and weekends (long nights — we had our third kid in April) designing, building, and iterating on a privacy-first journaling app based on my psychologist wife's clinical area of expertise — value and identity alignment[0].

You can check it out at www.clearlyhq.com.

Why a journaling app?

We've had tens of thousands of people over the last two years take the Values Navigator[1] assessment, a little web tool I put together based on decades of cross-cultural research by Dr. Shalom Schwartz, which my wife uses extensively in her practice. The main feedback we've gotten from people has been: ok, but now what?

In her clinical practice, my wife often recommends journaling to drive consistent introspection and growth, so together we designed an app that lets you rate and describe your "alignment" with your values every day.

We've also partnered with other psychologists and experts on writing prompts in areas like career and relationships to help you reflect on how your values show up in your day-to-day experience.

On to the tech stuff!

After three or four false starts on learning iOS development, things finally clicked with SwiftUI + SwiftData. I love how SwiftData lets you transparently replicate the database to the user's private iCloud, so we can keep your data safe without our being able to ever see any of it.

This also why we decided to stick with iOS-only — while it's totally possible to provide this level of privacy-by-design on web and Android, it is effectively built in to iOS if you really buy into Apple's way of doing things (for better or worse).

We also decided to not have any form of account or registration to keep it as private as possible. The only server-side components are the writing prompts, which the app downloads out of a Supabase instance, and RevenueCat, which we will use to manage a premium tier subscription to give access to features like charts/trends and (maybe?) on-device private AI.

Feedback is of course welcome! Although the baby is sleeping through the night now, I'll still hopefully have a few hours a week to keep shipping fixes and new features.

Description: I often browse through subreddits like r/iosapps, r/macapps to find product opportunities & market gaps.

I noticed a pattern: users frequently ask for alternatives to existing tools when they're frustrated with current solutions.

These posts are a great source of inspiration for product ideas as users are actively searching for alternatives to products that they already use & they describe their pain points with the the current solution.

So I build a free tool, AlternativeWatch.com to collect & curate such posts.

What it does:

  • Monitors product-focused subreddits for "alternative to X" posts
  • Displays live feed of recent alternative requests
  • Lets you browse historical data of past requests
  • Sends curated opportunities twice a week via email

    Looking for feedback on:

  • Which additional subreddits would be valuable to monitor?
  • Better ways to categorize & enrich the opportunities
  • What other data sources can I use to add more value?

Due to the recent TikTok ban, we have seen a big surge of English-speaking users coming into Red Note (Xiaohongshu), the Chinese social media app. As a user on the platform and a software developer, I really enjoy the fresh content on there and it was eye-opening for me.

I noticed that the videos being uploaded by TikTok Refugees usually do not have Chinese subtitles, or have poorly translated ones. So I went ahead and put together a free tool to help add a clear Chinese translation onto the videos.

It has been fun seeing these new videos and sharing new ideas and thoughts with more people. I want to be able to share them with my family like my father (who loves fishing and gardening) and my girlfriend (who enjoys baking a lot). I hope my tool can help inspire people between US and China. Cheers!

Author: R-Taneja

Description: I'm an indie hacker. I've found that one of the best ways to come up with project ideas is to find apps that are popular, but aren't loved by their users. I typically spend hours searching the depths of the App Store and Google Play Store top charts, looking for apps with a high number of reviews, but a sub-3.9 rating (and ideally ones that haven't been updated by their developers in >6 months). I look for opportunities to add AI, refresh the UI, fix user complaints, etc., and build a better version of the app. I know there's a market need, and I know exactly what my users want.

I realized I was spending too much time on the idea discovery process, and would love a way to do it passively over the course of a few months (even while I'm building other projects). Several friends also expressed the same need, and this post by Greg Isenberg (https://x.com/gregisenberg/status/1868673184213467576) validated the method.

So, I automated the process and created BuildList - a weekly email newsletter with insights on neglected but popular apps that are ready for disruption.

This is a mini-calculator for you if you are a freelancers or self-employed and can offset business related expenses from your taxes.

The calculation is incredibly simple, but I have recreated it in excel sheets often enough that I thought I'd be worth putting it online for myself and others to use.

Happy calculating!

Author: BruceHN

Description: I've been using Carrd for years to build sites for my personal projects, but one thing always frustrated me—SEO.

Carrd’s single-page structure with hash-based navigation (#sections) makes it almost impossible for search engines to properly index your content. No real URLs, no sitemaps, and limited meta tags meant my sites just weren’t showing up in search results.

That's why I created a small tool to solve SEO for Carrd sites:

- Multi-Page Structure: ZerpHost transforms your Carrd site into a properly structured website with real URLs for each section (no more # links).

- Auto-Generated Sitemaps: It automatically creates a sitemap so search engines can actually find and index your content.

- Optimized Meta Tags: Each page gets proper meta tags and canonical URLs, giving your content the SEO love it deserves.

It would be great to get your feedback on this solution, how it works for you, and what you think can be improved.

Author: TheBengaluruGuy

Description: Hey HN, we’re excited to share Doctor Droid, an AI-powered Slack bot for faster Kubernetes troubleshooting.

After two years of iterating, we’ve built a solution that lets you check pod statuses, restart pods, run custom commands, or diagnose complex issues — all from Slack.

Why we built it:

We noticed SREs often spend a lot of time jumping between terminals, dashboards, and docs to diagnose K8s issues. Our goal is to bring debugging directly into your team’s workflow (i.e., Slack), guided by an AI assistant.

How it works:

Sign up Invite the bot to your Slack channel Connect your Kubernetes cluster Start chatting (e.g., Doctor droid restart unhealthy pods in cluster x)

Key features:

AI-driven assistance for diagnosing and troubleshooting Simple UI within Slack to check logs, restart pods, etc. Proxy option for clusters not publicly accessible (GitHub repo)

What’s next:

Expanding beyond K8s to 40+ cloud-native integrations (private beta live) Leveraging existing SOPs, docs, tribal knowledge (upcoming feature) Automating postmortems, documentation updates, and scripts

Free Credits:

Feedback is super valuable to us—please let us know what you think! Grab 500 free credits (worth $50) if you sign up before January 31.

Docs & more:

Docs: docs.drdroid.io ProductHunt: https://producthunt.com/

Who we’re looking for: Anyone dealing with K8s day-to-day—your feedback will shape our roadmap!

Thanks for checking it out. We’d love to hear your thoughts, critiques, or questions in the comments!

Author: AleLuppi

Description: Hi HN!

In the last months I've been working on a JS package to integrate AI function calling directly into frontend frameworks, with little to no knowledge about AI required.

It works like this:

1. Design your actions (i.e. which JS functions you want to enable from GenAI).

2. Connect an Input to package's trigger (1 line of code).

3. When your user submits their needs, the API automatically run the actions with the best parameters.

Example: you are the owner of HN.

- User writes their need "I want to submit a 'Show HN' post similar to the best performing of 2024. My app is for pizza ordering".

- Using the package, the following actions are sequentially triggered: search(filter_by=&#x27;year&#x27;, filter_val=2024) -> sort(field=&#x27;points&#x27;, asc=true) -> write_post(text=&#x27;.....&#x27;) (disclaimer: I did not do it for writing this post ;) )

My goal is to allow devs to simplify user journey, finally improving conversion by reducing number of clicks to purchase.

Now, developers with some general knowledge about GenAI will get better results, but I'm working to make it effortless for anyone.

It's free to try, and I'd love to hear your feedbacks or requests for help -> https://userize.it

Show HN: Koroflow – Making cookie consent observable and developer-first - Project Screenshot

URL: https://koroflow.com/docs/components/consent-solution

Author: burnedchris

Description: Hi HN! Creator here. I built this after struggling with cookie consent management at my previous startup. Traditional solutions are slow, provide terrible developer experience, and a lot of the time it give zero visibility into consent states.

We just cut our first beta release with:

  • 100% TypeScript consent management solution
  • shadcn/ui components (cookie banner & preference UI)
  • DevTools for debugging consent states
  • ~6kb bundle size

    Try it out: https://koroflow.com/docs/components/consent-solution

    The vision is bigger - we're building a full privacy infrastructure platform with:

  • Cloud consent state management
  • Version control for privacy policies and consent texts
  • Unified event relay system (think Segment for consent)
  • Deeper consent profiles

    Would love your feedback, especially on developer experience and performance. All suggestions welcome!
