2. Show HN: A terminal tool for Logseq journal entries
URL: https://github.com/jrswab/lsq
Author: jrswab
Description: Creator here. I built lsq to solve a simple but annoying workflow problem: having to leave the terminal just to make quick notes in Logseq.
Technical details:
- Written in Go using Bubble Tea for the TUI
- Reads Logseq's config.edn for format preferences
- Supports both external editor ($EDITOR) and TUI modes
- Handles both Markdown and Org formats
Core design decisions:
- Zero-config default installation (uses standard ~/Logseq path)
- Single command to open today's journal (just 'lsq')
- TUI mode for Logseq-specific features (TODO/priority cycling)
The project started as a simple editor launcher but evolved to include a TUI when I realized certain Logseq features couldn't be easily replicated in a standard text editor.
Code and installation instructions are in the repo. Feedback and contributions welcome.

URL: https://docs.screenpi.pe/docs/plugins
Author: louis030195
Description: hey folks!
creator here. built this because i was tired of dumb context-unaware AI.
i used to build RAG with gpt-1 back in the day, it was so hard to tame it!
screenpipe records everything happening on your desktop (screens, voice, keyboard, mouse) 24/7, processes it through OCR/STT, and serves it through a clean API. think of it as a memory bank for AI agents.
tech stack:
- rust + (tauri app or pure CLI based) for the core (fast af)
- typescript + bun for TS plugins
- works on macos/win/linux
- fully local & open source
brew install screenpipe to try it out. would love your feedback!

Author: niggo2k
Description: Hey HN, I'm a student and I creating websites in my free time.
So I noticed I was repeatedly setting up the same infrastructure for these projects and I want to help people to avoid the first headaches of starting a new project. This repetitive setup was eating into valuable time that could be spent on actual business building.
Built by a solo founder, for solo founders. Stop wasting time on infrastructure and focus on what matters: building your business.
I hope this boilerplate will be as helpful to you as it is for me. Would love your feedback pls :)

Author: worotyns
Description: Hey everyone!
I’ve developed a few tools that I wanted to share with the community:
https://clipush.deno.dev A simple way to send web push notifications using cURL, making the process much easier to integrate into your workflow. (An experiment for personal usage.)
https://request-bin.deno.dev A tool that acts as a real-time HTTP request debugger with SSE logging to track and analyze requests efficiently. (Created after requestb.in introduced limits on free accounts. Personally used for testing webhooks.)
https://lock-states.deno.dev A service to manage lock states across distributed systems, helping to ensure consistency in shared resources. (Personally used in my CI/CD pipelines to handle asynchronous tasks and wait until they are done.)
The UI on these services is quite limited, but they're just simple tools ;-) Let me know if you find them useful!

9. Show HN: Preswald – AI Data Engineer in VSCode for Local Testing, Metrics
URL: https://www.preswald.com/
Author: amrutha_
Description: Hey HN, We're rolling out Preswald: an AI data engineer that lives inside VSCode. The goal is to make setting up and managing your startup metrics stupid simple—all from your editor, without adding SaaS tools, dashboards, or extra steps.
Why?
Most early-stage teams cobble together metrics using SQL, Python scripts, manual exports, and spreadsheets. We built Preswald to simplify that whole mess and keep it close to where engineers are comfortable: in their codebase.
What Preswald Does:
Local Testing: Write your SQL or transformation scripts directly in VSCode and test them locally before deploying. Preswald provides real-time validation and sample output previews to cut down the cycle of query-run-fix-repeat.
Code Completion and Suggestions: Preswald autocompletes data transformations in SQL, helps with joins, checks your references, and prompts for missing details. It understands common patterns like churn and activation rates—no need to reinvent the wheel or dig through notebooks.
Lightweight Analytics in VSCode: Get metrics like retention or churn set up in minutes, without exporting to another environment. Preswald can show sample metrics outputs as you work—helping you spot mistakes before they compound into bad analysis.
Automation, Versioned in Code: Define your pipeline in pipeline.yml and deploy directly with preswald deploy pipeline.yml. No complex cron jobs, no broken scripts—Preswald automates ingestion, transformation, and delivery in a clean workflow. If something breaks, Preswald tells you what happened and suggests fixes.
How it Works:
Built on SQL Parsing and AST Analysis: Preswald analyzes your queries using abstract syntax trees to identify patterns and inefficiencies. It helps prevent redundant calculations or inconsistent joins and gives you suggestions to fix them. Real-Time Feedback: As you type in VSCode, Preswald generates inline comments, suggesting better SQL snippets, missing joins, or potential optimizations. We want to reduce the manual back-and-forth between writing queries and discovering runtime errors.
Who It’s For:
- If you’re a founder or part of a small team, Preswald can be your missing data engineer—saving you time that would otherwise be spent manually maintaining metrics.
- If you’re a data engineer, this keeps your analytics in one place, gives you better version control, and helps automate testing and verification locally, all while reducing the tool overhead.
Why VSCode?
Everyone’s already in VSCode, so we figured, why create yet another dashboard? Preswald tries to bring the data engineering workflow into the same place you write the rest of your code, treating metrics setup like part of the codebase rather than a separate, duct-taped mess.
We’re launching in private beta right now. If this sounds like something you could use, you can sign up for early access here: preswald.com
We’d love your thoughts or feedback.

10. Show HN: First Contact – Simple Contact Us Forms
URL: https://first-contact.net/
Author: hi_hi
Description: I built https://first-contact.net/ primarily as a learning exercise for learning React and NextJS, running on Cloudflare. A secondary goal was to address a slight gap I saw (to be honest, I didn't look super hard, and have since found something very similar, which I'll get to) in enabling users to get in contact as painlessly as possible.
How it works:
- Sign up for an account, where you provide a project name (this is used for the forms public url)
- Grab the html snippet from the How To page, which is a link to your public form.
- Customise your forms header colour scheme and home link to resemble your own website or brand (this is super limited at the moment)
- Embed the html snippet on your own website.
You can then manage any messages received from your dashboard.
Give the form a go without any signup, either directly from the homepage https://first-contact.net/ Or from the contact form that is created when you sign up for an account (here's one I made earlier) https://first-contact.net/first-contact/contact-us
The idea came about when I created https://listofdisks.com. I wanted a simple way for people to contact me from the site. I thought about the usual social channels, but I don't really do socials and didn't want to create new accounts. I also didn't want to force others to need accounts just to send me lovely and thoughtful messages. I could have created a one off contact form for the site, but that seemed like too much work for the handful of people who would visit the site, and probably don't want to send any messages about hard drives, or life in general. This idea seemed like a fun way of learning some new technologies, and might be useful to other people in the same situation as me. A Google form was probably the closest to meeting my needs from a functional point of view, but they offered no branding customisations.
I would be remiss of me not to mention the fine folks at https://goodenough.us/, especially Cade who was generous enough to reply back to my random message :-) They built https://letterbird.co/ which I only discovered a couple of weeks ago, but it was exactly the kind of thing I was looking for before building First Contact. So yeah, I should have looked harder. I didn't go the email route though, so there's that differentiator. :-)
For those interested in the tech. It's NextJs deploying to Cloudflare, pages and workers, using Wrangler. Persistence is done with Cloudflare D1 SQLite. Authentication is handled by Supabase. Frontend is Shadcn and Tailwind. I'm not particularly attached to any of these things, but will say having backend and frontend and apis all in one spot with NextJs is nice, once you overcome its...idiosyncrasies. I'd probably try a different auth provider next time though, but Supabase is easy to get up and running and is nicely documented.
Hopefully other one man bands and startups find this useful.

16. Show HN: Jinbase – Multi-model transactional embedded database
URL: https://github.com/pyrustic/jinbase
Author: alexrustic
Description: Hi HN ! Alex here. I'm excited to show you Jinbase (https://github.com/pyrustic/jinbase), my multi-model transactional embedded database.
Almost a year ago, I introduced Paradict [1], my take on multi-format streaming serialization. Given its readability, the Paradict text format appears de facto as an interesting data format for config files. But using Paradict to manage config files would end up cluttering its programming interface and making it confusing for users who still have choices of alternative libraries (TOML, INI File, etc.) dedicated to config files. So I used Paradict as a dependency for KvF (Key-value file format) [2], a new project of mine that focuses on config files with sections.
With its compact binary format, I thought Paradict would be an efficient dependency for a new project that would rely on I/O functions (such as Open, Read, Write, Seek, Tell and Close) to implement a minimalistic yet reliable persistence solution. But that was before I learned that "files are hard" [3]. SQLite with its transactions, BLOB data type and incremental I/O for BLOBs seemed like the right giant to stand on for my new project.
Jinbase started small as a key-value store and ended up as a multi-model embedded database that pushes the boundaries of what we usually do with SQLite. The first transition to the second data model (the depot) happened when I realized that the key-value store was not well suited for cases where a unique identifier is supposed to be automatically generated for each new record, saving the user the burden of providing an identifier that could accidentally be subject to a collision and thus overwrite an existing record. After that, I implemented a search capability that accepts UID ranges for the depot store, timespans (records are automatically timestamped) for both the depot and key-value stores and GLOB patterns and number ranges for string and integer keys in the key-value store.
The queue and stack data models emerged as solutions for use cases where records must be consumed in a specific order. A typical record would be retrieved and deleted from the database in a single transaction unit.
Since SQLite is used as the storage engine, Jinbase supports the relational model de facto. For convenience, all tables related to Jinbase internals are prefixed with "jinbase_", making Jinbase a useful tool for opening legacy SQLite files to add new data models that will safely coexist with the ad hoc relational model.
All four main data models (key-value, depot, queue, stack) support Paradict-compatible data types, such as dictionaries, strings, binary data, integers, datetimes, etc. Under the hood, when the user initiates a write operation, Jinbase serializes (except for binary data), chunks, and stores the data iteratively. A record can be accessed not only in bulk, but also with two levels of partial access granularity: the byte-level and the field-level.
While SQLite's incremental I/O for BLOBs is designed to target an individual BLOB column in a row, Jinbase extends this so that for each record, incremental reads cover all chunks as if they were a single unified BLOB. For dictionary records only, Jinbase automatically creates and maintains a lightweight index consisting of pointers to root fields, which then allows extracting from an arbitrary record the contents of a field automatically deserialized before being returned.
The most obvious use cases for Jinbase are storing user preferences, persisting session data before exit, order-based processing of data streams, exposing data for other processes, upgrading legacy SQLite files with new data models and bespoke data persistence solutions.
Jinbase is written in Python, is available on PyPI and you can play with the examples on the README.
Let me know what you think about this project.

25. Show HN: Electrobillion, a city builder game where you build the power grid
URL: https://evrimzone.itch.io/electrobillion-alpha
Author: evrimoztamur
Description: Hi everybody!
After four months of hard work, I'm finally launching the demo for my little game.
It's called electrobillion, and it's a city builder where instead of building the city, you build its power grid. As the city consumes more power, it sprawls out further, and demands ever-increasing amounts of electricity!
It was born out of the confusion I had one day when I turned the lights on, and realised I had no clue how electricity made it to my house. I started digging around, and soon figured out that it was a lot more complex than I could have ever imagined it to be.
In turn, I set my sights on building a game such that others also get a rough idea of how the electricity comes from various sources to our various sinks.
My goal with this game is to be educational. So far, I've worked on a rather superficial level of complexity. Electricity flows without much struggle, prices are fixed, and costs of various elements such as fuel or energy storage are not really accounted for. However, my ultimate goal is to strike a good balance between education, fun, and realism.
...
Like my last couple games (Maginet and Critter Showdown, both available on itch as well https://evrimzone.itch.io/), this one is also built in Rust. This time, I got a little fancier and included WebGL to improve the rendering performance of the much larger amount of sprites. Besides that, it's essentially pure HTML5, including all of the UI running inside the Canvas.
Don't hesitate to ask if you have any questions here, and check out the source code of my previous big release, Maginet (which is an online multiplayer chess-like puzzle game): https://github.com/evrimoztamur/maginet
...
I'm going to take a short week-long break from development before going for another sprint where I:
- Push players into a constant battle against the forces of nature and their own pollution.
- Design a larger simulation of the economic factors hindering your path to profits: Government policies, fluctuating market prices for fuel and resources, chaotic weather events.
- Include real-life mechanics such as marginal pricing systems, grid congestion, and long-term storage.
So watch out for more updates, and let me know how you liked it so far!

Hi, HN!
I am very new to web development, and am learning javascript, react and next.js this year. Here is my first app, after weeks of dev! Would love some feedback on it!
The page lets knitters save recipes they already own, or pin ones they find on the internet. Kind of like a mix of dropbox and pinterest. Once stored, the user can do some progress tracking and do a smart search for their recipes, based on progress, clothing type, etc.
The page is in Norwegian, but hopefully easy to maneuver as an english-speaker, as I have tried to follow basic web dev principles (like CTA, etc.)
Thanks guys!

URL: https://github.com/teamcoltra/gorandomcaps
Author: TravisPeacock
Description: I was building a program that needed to allow a user to set a hotkey but the program lives in the taskbar so there's no UI. I decided what I would do is enable the caplock key when they click "Set Hotkey" and then they can disable the caplock key (or set it to its initial state, rather) to indicate they have finished.
That project is still going but I got sidetracked by the idea that I could just build a program to randomly enable the caplock key every once in a while.
This isn't a program designed to calculate child malnutrition or do anything to stop genocide etc but I was able to do it in a few hours and learn some new tricks.
I hope this isn't too stupid for HN.

44. Show HN: LiveUI – Instant Mobile UI Updates, Streamlined Design Systems
Author: crispinluis
Description: Hi HN,
We’ve been working on LiveUI, a tool to address some common frustrations we’ve encountered in mobile UI development.
One thing we’ve noticed is how often designers and developers end up doing the same work twice. Designers create detailed design systems, but developers then have to reimplement those designs in code. This isn’t just inefficient — it can also lead to communication issues, inconsistencies, and delays.
Here’s a quick summary of the problems we’re trying to solve:
1. Mobile UI updates lag behind web.
2. UI updates must go through app stores, adding delays.
3. Design systems are hard to keep consistent across platforms.
4. Designers and developers struggle to stay in sync, leading to miscommunication and duplicated effort.
5. Developers often become bottlenecks for implementing UI.
What LiveUI Does:
• Instant UI updates: Roll out changes directly to users without app store delays.
• Unified design systems: Changes propagate automatically across the app, so developers don’t need to reimplement what designers create.
• Visual editor: Makes it easier for designers or other team members to directly contribute to the UI.
• (Coming soon) A/B testing: Test and optimize different UI variants or let our AI do it for you.
Our goal is to reduce friction between designers and developers so they can focus on creating great experiences rather than worrying about rework or miscommunication.
Here’s a link to our latest demo https://youtu.be/deeXNnzhZpQ and here you can sign up for free https://live-ui.io.
We’d love to hear your thoughts:
• How do you currently handle design-to-development workflows?
• Have you experienced similar issues with maintaining consistent design systems or rolling out UI updates?
Thanks for taking a look!

46. Show HN: I built an extension to contact Airbnb hosts direcly
URL: https://www.getaway.direct/
Author: fliellerjulian
Description: Hey HN,
Over the years, I’ve found myself frustrated with the extra fees Airbnb. While they provide a lot of convenience, the service fees often stack up to a point where they overshadow any potential savings. I started wondering if there was a way to connect directly with property hosts and skip the middleman entirely.
That curiosity led me to build getaway.direct, a free Chrome extension that helps travelers save money. It works like this:
1. You browse listings on Airbnb.
2. The extension scans for direct booking links, host websites, or social media profiles where you can reach out to the host directly.
3. It shows those results instantly, so you can compare prices, avoid service fees, and book smarter.
The main idea is to provide transparency. A lot of hosts already have their own websites but rely on platforms like Airbnb for visibility. This tool helps surface those direct options, which can often save you 10-20% per booking.
I’d love to hear your thoughts:
Would something like this be helpful to you?
Also, I’m curious to get feedback on ways to improve the tool—whether it’s adding more integrations, improving usability, or something else entirely.
Thanks for reading! Let me know what you think.

49. Show HN: SpeechPro – Perfect Your Presentation with AI in Seconds
Author: bernking
Description: Hi HN,
I’m Bernardo, co-founder of SpeechPro, and I’m excited to introduce a platform we’ve built to help people master one of the most valuable skills in the world—public speaking.
The Story Behind SpeechPro
SpeechPro was born out of my frustration during university when getting meaningful feedback on presentations felt impossible. Teachers were vague, peers were hesitant to critique, and practicing alone wasn’t enough. We realized this was a universal challenge, so we built SpeechPro to provide actionable, AI-driven insights that help speakers of all levels improve.
The Problem
Public speaking is tough, and finding effective tools to practice is even tougher.
- Feedback is often subjective or shallow.
- Practicing alone doesn’t identify improvement areas.
- Trial-and-error methods waste time for professionals.
How SpeechPro Solves This
SpeechPro provides clear, personalized feedback in a few simple steps: - Upload or Record: Drag and drop your audio file or record directly on the platform.
- Get Feedback: Our AI analyzes tone, clarity, pacing, and delivery. You can even get feedback on content if needed.
- Tailor the Experience: Set goals like target duration, audience context, or focus areas.
- Track Progress: Use detailed metrics to monitor improvement over time.
Why SpeechPro?
- Practical for Everyone: Students, professionals, and content creators can all benefit.
- Actionable Insights: Get specific feedback you can use immediately.
- See Your Progress: Analytics make your growth measurable.
We’d Love Your Feedback
Does SpeechPro address your biggest pain points with public speaking? Are there features you’d love to see?SpeechPro is free to try, and early adopters can access exclusive discounts on premium plans with advanced features.
We’re excited to share this with the HN community and hear your thoughts. If public speaking has ever been a challenge—or if you’re looking to level up—SpeechPro is here to help!

52. Show HN: Voice to Text, but User Friendly
URL: https://sona.wtf
Author: floriankiem
Description: We started having issues getting our notes done after having conversations with many other builders in 2023 Therefore, my friend and I started building Sona Insight, an AI-powered transcription app (iOS).
I know every "indie-hacker" is doing something similar now (which I want to speak about later in this post), but our app has some features (e.g. creation of summary templates, own AI backend built on top of OpenAI's whisper, and a unique architecture) that make it unique. Everything is auto-saved to your account and synced to the cloud (so when we release our web app you can see and edit everything on your desktop).
As we built this for ourselves the goal never was to make a gigantic thing out of it as we worked on it in the evenings. But the app gets used successfully and we have a lot of subscribers compared to the marketing effort we invested till now.
What I want to leave for discussion here, with the context given, is why on earth are that many people building something so similar? When we started posting about it on X, we only saw apps from 2018 that had another approach, however, in October and November of this year it felt like every second post was about an app built similarly. Looking into it they always seemed to only do one API call to OpenAI or Deepgram directly, but some of them didn't even work right.

54. Show HN: Managed Redux Toolkit: Autogenerate Your RTK Definitions
URL: https://celestialdb.github.io/
Author: KritiKay
Description: Redux Toolkit (RTK) provides a lot of primitives to build performant frontend applications. Celestial generates RTK code for your backend (with additional features), exposing an intuitive hook-based API. So you can have all the benefits of RTK without having to familiarise yourself with the underlying framework.
Essentially, we write the backend wiring code for your frontend. You get simple-to-use hooks, which implement advanced backend sync & state management patterns. You also get a fast, snappy application out-of-the box.
You can also think about it like this: Celestial generates a unified state layer that contains your server state and any other state that you decide to store. It exposes hooks to interact with the state, while constantly keeping client state in sync with the backend. Your UI simply plugs into the state layer using a hook-based API to manage data flow for your web app.
UI development can broadly be categorised as (1) interacting with the backend to fetch data and push updates, and (2) writing and styling the UI. The vision is to automate (1) end-to-end, allowing devs to focus on (2). Like how Firebase/Supabase (when they began) abstracted away the implementation of chat.
An analogy can be found in the data world: before the data analyst can build a data dashboard, the data needs to be supplied to the dashboarding tool from various sources. This data fetching is generic enough to be abstracted away. The analyst simply writes SQL on their dashboarding tool to build their dashboard, without worrying about bringing the data in. They assume that the data will be present in a predefined structure and will update at a regular cadence.
In the frontend domain, sophisticated tools for data fetching and updating the backend exist. For ex. RTK, RTK Query, TanStack Query, SWR. But a developer still has to tie everything together themself. IMO, this can be automated, more so because of generative AI.
The idea is to abstract away all details of backend-interaction so the frontend developer can manipulate the data & develop the UI as if the data rests in in-memory data structures on the frontend itself. I am assuming that taking away the burden of backend interaction (and all its various nuances) would make life easy/save time for some devs and would empower other devs by giving them tools to do more. Please feel free to validate or invalidate this assumption :)
All comments & feedback welcomed. Feedback is the fuel that drives my work!

55. Show HN: Py-gen-ML – a library to generate robust ML code from a schema
URL: https://jostosh.github.io/py-gen-ml/
Author: jalapenjos
Description: py-gen-ml (https://jostosh.github.io/py-gen-ml) is a Python library that aims to simplify the process of configuring machine learning projects. It uses Protobuf schemas to define configurations and then automatically generates code based on those schemas. This includes code for Pydantic base models, patch configurations, sweep configurations, command-line interfaces, and entry points.
One of the key benefits of using py-gen-ml is that it reduces the amount of manual work that is required when making changes to configuration schemas and/or values. Atomic code generation guarantees consistency across Pydantic base models, YAML parsing, CLI parsing, sweeps and any other code that is generated.
Another benefit of py-gen-ml is that it offers strong typing. This means that the code that is generated is guaranteed to be correctly typed and easier to understand for you, your team, your IDE, and your type checker.
Similar to other config frameworks like Hydra, py-gen-ml supports flexible YAML configurations with advanced referencing and variable support within YAML files. In addition, generated JSON schemas can be used to validate YAMLs as you type.
py-gen-ml can be installed using pip:
> pip install py-gen-ml
There is a quick start guide available to help users get started with py-gen-ml. There is also additional documentation that covers topics such as the command-line interface, parameter sweeps, generated factories, and a Cifar 10 example project.
In short: using py-gen-ml can help you to manage complex ML projects more efficiently, streamline experiment running and hyperparameter tuning, and reduce the impact of configuration changes on your workflow.
The project is still at an early stage, but ready for feedback!
