1. Show HN: Tramway SDK – An unholy union between Half-Life and Morrowind engines
URL: https://racenis.github.io/tram-sdk/why.html
Author: racenis
Description: Hello everyone, I would like to see if there is any interest in this little project that I have been working on for the past few years.
Could be relevant, seeing the direction in which the mainstream game engines are going.
I didn't really like any of the already existing options, so I tried to make my own and it turned out to be easier than expected.
It's sort of like a low-budget Unreal/Source, but with open-world streaming support and it is free and open source. Very old-school. But optimized for more modern hardware. Very fast too.
Still not production ready, but it seems like it is mostly working.
I want to finish a few larger projects with it to see what happens.
Btw, the name is probably temporary.

4. Show HN: Galaxybrain.com – a JSON-based knowledge system
URL: #
Author: j0ncc
Description: Hi HN,
I’d like to share a project I’ve been working on called GalaxyBrain. It’s a tool for organizing information.
Key features: Embeddable dynamic metadata: as you type, metadata is generated in the background. This metadata can be accessed and embedded directly into the page.
Light programming concepts built in: you can add custom values (think variables) to any page, then reference those values across different pages to build dynamic relationships.
Metadata can be chained together: referencing values on other pages, or by using a formula. Updates to anything flow through the entire system (like a spreadsheet).
It runs on local JSON files: plan is to offer a hosted version, with structured end points for everything so you can use it as a datastore. If you host the json files locally it will be free forever.
I use it to build a model of my life. Everything I care about has a page, each with its own dynamic metadata that updates in real time as things change within the system. Each page acts like a little dashboard for that thing.
The app is pretty sprawling, and there's still some bugs on the fringes. I'm onboarding people slowly and fixing bugs as they come up. I wanted to share it early to get feedback and see if I was onto something.

Description: In an effort to understand it, I put together a simple, pure python implementation of HNSW, an approximate nearest neighbor library. Learned a lot, and I think for anyone interested in vector search it's an exercise that's absolutely worth doing.
The code is optimized (imo) for readability, and working (albeit, quite slowly) on putting together a tutorial that walks through the motivation and implementation of HNSW.
There's also working code examples for using the library for text and image search with sentence transformers and CLIP!

9. Show HN: Kindred – Find an accountability buddy near you for your hobbies
URL: #
Author: hansonkin
Description: It's the new year and many of us have resolutions to start new hobbies or focus more on existing ones. Having someone you can meet with to do or talk about a shared activity helps us stay motivated and more importantly, makes it more fun. Finding an accountability buddy can be tricky because a good match involves several factors. Ideally, you want someone nearby so it's convenient to meet up, someone at a similar skill and commitment level and someone who shares your interests/styles/inspirations within the hobby.
In my case, I would consider myself an intermediate guitar player and have always wanted to find a practice partner. Living in NYC, there is no shortage of musicians, but many have more serious goals and aspirations than I do. As a hobbyist, my main focus isn't playing gigs or being in a band. I’m not trying to practice for hours every day to become an expert. I just want to find someone to play some songs with casually for fun. I’m sure this person exists in my neighborhood, but I had no easy way to find them.
There are apps for specific activities like music collaborations, tennis, or basketball, but I found they often cater to a more serious crowd. Beginners and casual dabblers are usually left on the sideline. That’s why I built Kindred, a way for anyone to connect with others through hobbies.
Here’s a quick overview of how it works:
- Set preferences for age, gender, and location to help you find compatible buddies nearby.
- Create a profile focused on your experience level and specific interests within your chosen hobbies. Unlike typical social media, superficial details like looks, education, or career aren’t emphasized.
- Meet people through plans. Plans are like traditional events but can have more flexible time and date. You can choose "sometime this week" or even "whenever." Plans with small groups of 4-5 people are encouraged but you can also choose one-on-ones or larger groups. It should feel like you're just making a post about what you want to do to neighbors who fit your preferences instead of it feeling like you're formally hosting a public event.
Check it out here: https://kindredsocialapp.com. The app is currently available for iOS only.
I’d love to hear your feedback and answer any questions!

10. Show HN: TonboLite – Scale SQLite with S3, Minimize ETL
URL: https://github.com/tonbo-io/tonbolite
Author: ethegwo
Description: Hi! I am Tzu and the team from Tonbo here.
TonboLite: https://github.com/tonbo-io/tonbolite is a SQLite extension based on Tonbo: https://github.com/tonbo-io/tonbo. It enables SQLite to create tables suitable for analytical processing on target platforms like WebAssembly in browser and efficiently write data. The data in the tables is organized as tiered Apache Parquet format files, stored on demand either on local disks (using OPFS as native I/O) or object storage services (such as S3). You can use it by creating virtual tables in regular SQLite.
TonboLite started with the exploration of Tonbo application. The goal of Tonbo is to write data for analytical processing (like log processing, metrics monitoring, or text search) to unlimited remote storage in SQLite or PostgreSQL.
We tried SQLite as it is the most popular transactional database for the edge. One of the most requested improvements for SQLite is better support for append-only writes (e.g., logs, time-series data), which are common in analytical data. Append-only writes present two main challenges for SQLite:
- SQLite3 uses B-Trees as its storage structure. B-Trees perform well for random access but are not optimized for write efficiency in append-only scenarios like log-structured databases.
- Append-only data often involves large write volumes, making it difficult to store extensive historical data in a single-machine environment long-term. However, Tonbo is well-suited to address these two issues:
- Tonbo organizes Parquet files into an LSM Tree, a database structure highly optimized for concurrent append-only writes.
- Tonbo supports gradually writing historical files in the background to horizontally scalable storage services (such as S3).
This project is still in the very early stages. If you are interested in the project's goals and future developments, welcome to join the discussion: https://discord.gg/j27XVFVmJM. We are happy to answer any questions you may have.

URL: https://github.com/fbilhaut/gline-rs
Author: fbilhaut
Description: Hi everyone, wanted to share about gline-rs, an inference engine for GLiNER models written in Rust.
This family of lightweight language models proved to be efficient at zero-shot Named Entity Recognition (NER) and other tasks such as Relation Extraction, while consuming less resources than large generative models (LLMs).
This implementation has been written from the ground up in Rust, and supports both span- and token-oriented variants (for inference only). The goal is to provide a production-grade and user-friendly API in a modern and safe programming language, including a clean and maintainable implementation of the mechanics surrounding these models.
For those interested, it can also help getting a deep understanding of GLiNER's operation.
Thanks for any feedback or interest !

18. Show HN: Persistent GitHub Action Runners – Buildalon
Author: afarchy
Description: We noticed our Unity game builds are much slower on GitHub than locally. Here's why:
- The runner needs to install the game engine and dependencies every time.
- The build artifacts are not cached between runs.
We learned we can register self-hosted runners to build on our own machines. But this doesn't scale - hosting runners on Azure or AWS gets expensive quickly.
So, we built a system to manage runners more intelligently. When there's a job, a runner is quickly made available. When there are no jobs, we can optimize aggressively to save on costs.
Unlike GitHub's runners, these persist₁ from run to run, reducing our build times over 50%.
This strategy works great for us, so we turned it into a service. Welcome to Buildalon!
Getting started:
- Install the Buildalon GitHub App.
- Replace runs-on: windows-latest with buildalon-windows (or buildalon-ubuntu).
- That's it - you get 200 free minutes to try it out.
Thanks in advance for your feedback!
[1] We know consistency is a core principal in DevOps, and stateful runners go against that. But sometimes, we think speed is more important. If needed, we can reset the runner any time.

20. Show HN: I've been posting a sound I made everyday day for the last year
URL: https://www.listenfaster.com/main/1min/
Author: listenfaster
Description: Hi - I'm part composer, part engineer and big fan of reading blogs where people learn out loud or with the garage door up by sharing their notebooks or journals. I've been doing this in Moleskines for years (going back to the 80s) but made it a new year's in 2024 resolution to post SOMETHING everyday, so long as I created the sound. I have a big archive of demos and seeds of ideas, so I figured it wouldn't hurt to do something with those in the process.
Being so steeped in programming for the last 30 years, a healty chunk of this material is made via coding with Csound, TidalCycles, some raw crude apps I've written from scratch, so I thought it would be of interest to the HN world.
Admittedly it's pretty self-indulgent, with a lot of names and references you won't get unless you know me, and the pics are often something from my camera roll that day if there's not a scan of music notation to share.
I think it's a very indieweb approach to take, though I wasn't aware of there being an indieweb movement until... 2022 probably. Thanks for reading and listening - let me know what you think.
Here's the ASK HN Part:
Here are a few blogs where someone is doing this learning out loud. Any others come to mind?

So far, it has helped me browse websites, send quick messages to Slack (or Slack useful information to myself directly), and do trip planning.
I'm curious to see if people would find it useful and what they would use it for. Currently, I'm soft-launching it to 100 test users to collect feedback. I only have a few MCP tools added so far, but I'm hoping to add more. Would love to know what tools you’d like to see next.

25. Show HN: End-to-end encrypted, peer-to-peer VPN tunnels for hackers
URL: https://reliquary.se
Author: jvink
Description: Hello HN,
I would like to announce the soft availability of The Reliquary [0]: A "VPN" service for hackers.
Note that VPN is in air quotes here because it is not a traditional consumer VPN your strange uncle uses to watch questionable online content.
With Reliquary you can setup end-to-end encrypted, peer-to-peer tunnels between your devices no matter where they are located.
The Reliquary was started after I built sanctum [1] to make it a bit easier to setup networks and tunnels between me and my hacker friends.
I ended up building a simple management API around sanctum and its cathedral mode that allows you to define networks and join devices into these networks, all the while keeping the shared secrets sanctum builds its security on completely in your hands while still providing meaningful ways of doing key rotations.
On your client devices you use some shell scripts reliquary provides to manage sanctum configurations, there's zero magic.
A cathedral in sanctum acts as a discovery point (think STUN) for your devices and can relay (but not read/alter) encrypted traffic when needed. They also facilitate key rollover by acting as a distribution point for your shared secrets (which are wrapped with per-device KEKs).
If your devices are behind reasonable NAT, they will move towards a peer-to-peer connection, leaving the cathedral behind.
Keep in mind that The Reliquary is directly aimed at the hacker crowd as one should be familiar with certain topics to be able to feel comfortable with it (you need to handle your own key management, network setup, etc).
A starting guide can be found at [2] for those who are interested.
I built this to be useful to me and my hacker friends, I hope some of you might find it equally useful - I am happy to answer some questions but I dislike writing on public forums (digital agoraphobia?)
You can get in touch with me via joris@sanctorum.se
Take care,

26. Show HN: Query Fast - Lightweight data analytics with AI
URL: https://www.query-fast.com/
Author: sverg
Description: Hi everyone!
I’m a software engineer with a passion for building products. After struggling to find a lightweight analytics solution for my own projects—one that wouldn’t require constant SQL tinkering—I decided to create Query Fast.
What is Query Fast?
- A lightweight data analytics tool aimed at individuals and teams who want to be data-driven without having to write SQL.
- An AI agent (powered by GPT-4o and Claude 3.5 Sonnet) that’s aware of your database and its schema, so you can simply ask questions in a chat interface.
- Integrated query runner in chat
- Automatic data visualization and data tables for quick insights.
- Drag-and-drop dashboards for building custom views.
- Compatibility with Postgres, Redshift, BigQuery, MongoDB, Snowflake, and more coming.
I found myself jumping between ChatGPT and SQL query tools for every new insight I needed, which felt too cumbersome. Query Fast aims to bridge that gap by letting you chat with your database, visualize results, and build dashboards — all in one place.
Check out https://query-fast.com/ for a quick test run. I’d love to know what you think, especially any features you’d want to see next or areas that might need improvement.

I track my budget, but I hate writing down how much I spent daily/weekly/monthly. So I built an AI parser for all of my banking SMS and Apple Pay taps
- GPT 4o-mini generates JSON with amount, merchant name, category, type (purchase, ATM, transfer), etc
- In dashboard, I can view/group/filter/search my expenses
- It also secure - no need to grant access to bank account. Just forward SMS/Apple Pay pushes via native iOS app
- It's free while in "beta"
I plan to add weekly/monthly reports, goals tracking, etc. Do you find it useful?
PS.: I'll be happy to give life-time premium in exchange for valuable feedback
P.P.: my US friends said that SMS notifications are not popular - so I added Apple Pay taps

Author: m_busel
Description: hi everyone!
when I was in college, I used to read one PG essay per day to learn about startups.
at the time, I wished there was a way to keep track of my progress.
years later, and after doing YC, I’m still re-reading his essays - so over the holidays I built an app to help keep my own progress.
it lets you mark essays as done, bookmark favorites, and sort by reading time.
built with [bolt.new](http://bolt.new) (zero affiliation) so the whole thing took a couple of hours.
and uses the bolt defaults of a supabase backend and hosted on netlify.
it’s a pretty limited app but hopefully helpful for some and planning to always be free.

39. Show HN: Cardstock- Free TCG Proxy Manager for Magic, Yugioh, & Pokemon
URL: https://cardstock.denta.co
Author: adenta
Description: Trading cards are awesome, but paying $30 for some cardboard isn’t. I’ve upscaled 60,000 cards from the entire catalog of Yugioh, Magic, Pokemon, & a newer game, https://elestrals.com. I've made it easy to build a decklist, download it, and then print at home. Modern inkjet printers got really good when nobody was looking. While it’s clear they’re not real cards, the upscaling makes them look great for casual play (these are not tournament legal). It’s totally free, give it a try!
Supplies: https://cardstock.denta.co/kb/supplies Printer Settings: https://cardstock.denta.co/kb/settings Instructions: https://cardstock.denta.co/kb/instructions
Overview: I built Cardstock because I had some scripts to do this lying around, and wanted to explore the new Rails 8 magic. Kamal 2 (kamal-deploy.org/) is a game changer, SQLite in production is fine, and the database backed solid family of gems work like a charm.
Compute I am renting a box on https://hetzner.com located in VA for $15/mo. This box has 8 gigs of ram and 2 vCPU's. This is such a deal compared to compute prices on https://render.com.
Kamal 2 This thing is amazing. Kamal gives me everything I could want (easy console access, easy shell access, a way to manage secrets, a way to see my logs, and letsencrypt support for DNS), all without a PaaS tax. The best part is the accessories feature: https://kamal-deploy.org/docs/commands/accessory/. I am running my main app with two accessories: Meilisearch(https://meilisearch.com) and OpenObserve (https://openobserve.ai). Instead of paying Algolia to host search infrastructure and sentry to host monitoring infrastructure, I’m hosting my own OSS without any fanfare.
Upscaling: To upscale the trading cards (a mandatory part of this build, scans are never high enough DPI). I am using this (https://replicate.com/nightmareai/real-esrgan) model. For upscaling every card, I've used under a hundred bucks of compute. This model was picked on a whim, but worked well enough that I didn’t compare other models.
I used SQLite combined with Litestream (litestream.io) for my database. While I considered Postgres, I hesitated due to uncertainties around handling backups on self-hosted infrastructure. This was my first time using SQLite in production, and it was functional but with some minor annoyances. Here’s what I encountered:
- No Default UUID Primary Key Type I had to set primary keys as strings and assign IDs manually from the application record. It’s an annoying workaround but manageable.
- No Native Array Columns Because SQLite doesn’t support array columns, I had to use its native JSON column type, which just felt icky. If I were working with something like embeddings, this would be especially annoying, because you couldn’t enforce all the records to have the same number of dimensions.
- Cryptic Errors At one point, a migration failed silently, leaving a cryptic error in schema.rb. The issue was resolved by rolling back the migration and redoing it, but it was once again, annoying.
- Litestream Defaults
Litestream deletes snapshots after 24 hours by default, which is far too short. When I tried to recover some data, I found it had already been deleted. Adjusting these defaults fixed the problem.
Solid Queue/Cache/Cable The solid family of gems are all backed by the database and were a pleasure to work with. Goal was to prevent needing to reach for redis, so you have one less thing to worry about. You end up with a little more latency, which is a totally reasonable tradeoff.
Conclusions We are moving into a post platform as a service world. Instead of buying a bespoke render.com or heroku, you just buy commodity compute and use Kamal to manage. It's like, pretty much all there, excited to see how this space matures.

42. Show HN: Rebuilt my "CodePen for server tech"
URL: https://tech-playground.com
Author: mkamner
Description: Hey all,
a long-ish time ago I built a basic site and API to run a couple of web servers and template engines with a user-specified configuration and get the output directly into the browser.
While I liked the minimal solution (some static HTML with a simple JSON API), I wanted to build out some more features, like saved snippets and, crucially, rate limiting for anonymous users. So I built a small Django app to handle all of that.
Somewhat accidentally this also lead to me building a custom "function as a service" backend thingy that allows for multiple, limited and timed, processes inside each execution.
So now it can do all that, while at the same time allowing me to add more tools in minutes, instead of one big messy script in ye olden ways.
Anything you would like to see a playground for?

44. Show HN: Created YouTube Shorts Downloader with just 2 v0 prompts
URL: https://youtube-shorts-downloader.com
Author: ahmednabi
Description: Last week I was testing to see how quickly I can create simple apps with v0 and bolt. I created a full-stack app with 5 prompts. This week I pushed it even further with a very detailed description of what exactly I wanted to do including screenshots from the previous app and created a simple YouTube downloader with just 2 prompts.
With the first prompt, v0 was able to scaffold the basic NextJS app, install the necessary libraries for YouTube downloading (I didn't even know ytdl existed for node), and build a fully working backend api and frontend client.
In the second prompt, I uploaded a screenshot of my previous app to make it look like that and it got it right, right away.
Fully functioning app with just 2 prompts. AI is unreal.

45. Show HN: GetHtml() open source web scraping waterfall fetcher
URL: https://github.com/andytyler/gethtml
Author: andyjtyler
Description: I’m open-sourcing a project that’s been in my web scraping toolkit for a while: Waterfall Fetch.
After building custom scraping infrastructure for startups again... and again... and again, I decided to do something potentially career-damaging. I’m making a generic version of my go-to solution available for everyone.
How does it work? Waterfall Fetch performs stealth/proxied fetches in sequence. If one fetch fails, it automatically moves to the next, more robust strategy—until it successfully retrieves HTML. Think of it as a resilient solution for web scraping.
Features:
- Supports custom fetch strategies (and proxies).
- Allows you to execute JavaScript on pages.
- Works with a simple getHtml() function.
- Fully documented.
And yes, it’s live now on NPM.
npm i waterfall-fetchIt even has a nice little docs site to help you get started.

46. Show HN: DB Stress Testing Tool
URL: https://github.com/freakynit/db-stress-bench
Author: freakynit
Description: 1. Simple, easily customizable and powerful database load testing tool.
2. Provides real-time in-browser aggregate stats.
3. Supports MySQL, Postgres, SQLite, and DuckDB.
4. Adding support for a new database requires a simple 3-method interface implementation.
5. Supports query templates allowing you to use a configured csv file to replace template variables at runtime (example: select * from Customers where customer_name = '${customer_name}')
6. Other usual stuff. A bit inspired from Apache Benchmark.

47. Show HN: Chrome extension to filter Google results to pre-2023 (pre-AI content)
URL: https://chromewebstore.google.com/detail/pre-ai-search-filter-goog/claajpcgaehlepegbiibddifpnlokckb
Author: olievans
Description: Built this to add a persistent toggle for filtering Google results to pre-2023. Yes, you can use date parameters manually, but having a one-click toggle has proven surprisingly useful for technical research.
Implementation details:
- Modifies search URL parameters for date filtering
- No analytics/tracking
- Lightweight, just handles date toggling
- No background processes
Been using it for my own development work. Posted on r/programming where other developers found it useful for filtering out AI-generated technical documentation and finding original solutions.
Happy to answer any technical questions about the implementation.

51. Show HN: CaddyFile Generator
URL: #
Author: pmx
Description: I wanted a tool to make managing my CaddyFiles easier so I created CaddyGen. It has presets for several server tools you may want to reverse proxy, allows you to set up custom hosts, has options for several options, etc. You can import your existing CaddyFile and manage with the tool.
It doesn't send anything to any servers, its all stored locally on your browser. If you don't trust it still, you can grab the source or use docker and self host it.
Made this with bolt.new because I wanted to evaluate the tool (i like it). I'd never have made this as quickly by hand.

What sets Max Deduct apart:
- Manage multiple businesses/gigs at a time
- Calculate depreciation on assets
- AI auto categorizes your transactions
I launched in December, I'm curious if there's interest in me continuing development.
Would love to hear what y'all need in bookkeeping!

56. Show HN: Prognoze – Leveraged Prediction Markets
URL: https://www.prognoze.xyz/
Author: pitahat
Description: Hey HN!
I built and launched Prognoze, a sustainable onchain prediction market platform that allows users to trade event markets with up to 10x leverage.
Leverage in prediction markets is made possible by a new-generation innovative virtual Automatic Market Market (vAMM) model purposely built for prediction markets. This model creates a synthetic leveraged trading experience without the need for liquidity providers.
Like Uniswap and other spot crypto markets, traders can trade an event market contract directly without needing counterparties, market makers, liquidity providers, or order books. The model ensures onchain liquidity based on constant product curves, as pioneered by Uniswap's AMM model.
Unlike perpetual futures trading platforms, market prices on Prognoze are path-independent and not anchored to any external sources of information, ensuring the stability and sustainability of the markets.
The lifecycle of a prediction market on Prognoze is split into two distinct trading stages. These stages use different profit-and-loss (PnL) calculation methods to ensure the sustainability of the markets and profitability for the traders.
Open Trading Stage: Traders buy Yes or No shares with leverage, and each trade impacts the YES and NO share prices. PnL is directly linked to the YES or NO share price, and traders can realize the position's profit or loss on demand.
Resolution Stage: After the market's outcome is accepted, trading ends. Winning traders divide the losing side's total collateral, while the losing traders lose the entire collateral of their positions in the market. To supplement traders' profits at this stage, the fees accumulated in the Reward Pool are shared with the winning traders.

57. Show HN: I built a 93 page eBook and landing page in 36 hours
URL: https://interviewadmin.com/ebook
Author: chw9e
Description: In just 36 hours, I created a landing page, a 93 page ebook, & everything needed to collect user contact info and email out the ebook automatically on submission.
I used Lovable, Figma, GPT o1, brandmark.io, Unsplash, Netlify, Supabase, and Resend.
Most of the 36 hours was designing the pdf files in figma and some back and forth with o1 as it was creating the content. If there were an agent that could use figma it would speed that up a lot.
Lovable blew my mind. So fast to get things up and running. The Supabase integration is great, and I was shocked at how easy it was to add a key for Resend. Really slick work by the lovable team on all those fronts.
The hardest part I ran into was getting a supabase edge function to work correctly. It gets triggered whenever a new row is added to the db to send out the email with the pdf in it, and getting the db and the function connected took a couple tries but lovable eventually got it.
There's also a non-ebook landing page here, in case you're interested in learning more about InterviewAdmin the product. https://interviewadmin.com

58. Show HN: Autopod, Automate Your Reading List to Podcasts
URL: https://github.com/falmanna/autopod
Author: abol3z
Description: Hi HN,
I've been reading so much content lately around LLMs for my work and research, so I built a simple tool to turn my "read later" links into podcasts to keep up with the super fast changes happening in the industry. It uses n8n, OpenAI, and Raindrop.io to pull content, generate scripts via AI, convert them to audio, and save the result to Google Drive. Now I can catch up on articles and papers while on the go.
It's cost-effective (~$0.20 or less for 20 minutes podcast) and fully customizable—you can tweak prompts, adjust lengths, or swap components. It is optimized for cost, so the voice quality isn’t perfect yet as is, but it can easily improve by swapping the TTS model with a better one.
The workflow is open source, and the setup is straightforward. Check it out and let me know your feedback or ideas for improvements!
