1. Show HN: I built an open-source data pipeline tool in Go
URL: https://github.com/bruin-data/bruin
Author: karakanb
Description: Every data pipeline job I had to tackle required quite a few components to set up:
- One tool to ingest data
- Another one to transform it
- If you wanted to run Python, set up an orchestrator
- If you need to check the data, a data quality tool
Let alone this being hard to set up and taking time, it is also pretty high-maintenance. I had to do a lot of infra work, and while this being billable hours for me I didn’t enjoy the work at all. For some parts of it, there were nice solutions like dbt, but in the end for an end-to-end workflow, it didn’t work. That’s why I decided to build an end-to-end solution that could take care of data ingestion, transformation, and Python stuff. Initially, it was just for our own usage, but in the end, we thought this could be a useful tool for everyone.
In its core, Bruin is a data framework that consists of a CLI application written in Golang, and a VS Code extension that supports it with a local UI.
Bruin supports quite a few stuff:
- Data ingestion using ingestr (https://github.com/bruin-data/ingestr)
- Data transformation in SQL & Python, similar to dbt
- Python env management using uv
- Built-in data quality checks
- Secrets management
- Query validation & SQL parsing
- Built-in templates for common scenarios, e.g. Shopify, Notion, Gorgias, BigQuery, etc
This means that you can write end-to-end pipelines within the same framework and get it running with a single command. You can run it on your own computer, on GitHub Actions, or in an EC2 instance somewhere. Using the templates, you can also have ready-to-go pipelines with modeled data for your data warehouse in seconds.
It includes an open-source VS Code extension as well, which allows working with the data pipelines locally, in a more visual way. The resulting changes are all in code, which means everything is version-controlled regardless, it just adds a nice layer.
Bruin can run SQL, Python, and data ingestion workflows, as well as quality checks. For Python stuff, we use the awesome (and it really is awesome!) uv under the hood, install dependencies in an isolated environment, and install and manage the Python versions locally, all in a cross-platform way. Then in order to manage data uploads to the data warehouse, it uses dlt under the hood to upload the data to the destination. It also uses Arrow’s memory-mapped files to easily access the data between the processes before uploading them to the destination.
We went with Golang because of its speed and strong concurrency primitives, but more importantly, I knew Go better than the other languages available to me and I enjoy writing Go, so there’s also that.
We had a small pool of beta testers for quite some time and I am really excited to launch Bruin CLI to the rest of the world and get feedback from you all. I know it is not often to build data tooling in Go but I believe we found ourselves in a nice spot in terms of features, speed, and stability.

I’d love to hear your feedback and learn more about how we can make data pipelines easier and better to work with, looking forward to your thoughts!

2. Show HN: Adventures in OCR
URL: https://blog.medusis.com/38_Adventures+in+OCR.html
Author: bambax
Description: Hello HN!
In a recent "Ask HN: What are you working on?" thread, I mentioned I was working on OCRing a large book:
https://news.ycombinator.com/item?id=41971614
The post generated some interest so I thought I would keep HN posted.
The book is Saint-Simon’s Memoirs -- an invaluable historical account of the French court under Louis XIV, full of wit, sharp observations, and of incredible literary value. I'm OCRing the edition of reference made between 1879-1930, that contains a lot of comments and footnotes: 45 volumes, ~27,000 pages.
Here's a link to a blog post that describes the techniques used so far (the project is still ongoing):
https://blog.medusis.com/38_Adventures+in+OCR.html
But you may also directly access the result here:
https://divers.medusis.net/boislisle/pub
This web app (not optimized for mobile, sorry) solves a tricky problem of preloading images efficiently. In short: preloading the next image isn't enough, since browsers will repaint if an image is moved, or scaled. Or browsers won't paint at all if visibility is hidden or opacity is zero, and will paint only when those values change. On an average, slow machine, this takes visible time. But if an image is simply behind another element, it will be painted, and the removal of the covering element or changing the z-index will not trigger a repaint.
(Preloading is important because it lets one review results fast; if one has to wait 150-200 ms between images it's simply discouraging).
Would love to hear feedback; happy to answer any question!

4. Show HN: We built Premagic – a tool that turns event attendees into marketers
Author: mevinbabuc
Description: At every event, tons of photos are taken, but they rarely get used well. As organizers, you post a handful on social media while the best moments are scattered across attendee phones. And if you’re hoping for engagement or visibility? It’s a grind.
We built Premagic, an event tool that flips this problem.
Here’s what we do:
Instant Photo Sharing: We use AI to auto-select the best event photos and share them in real time with attendees. They get photos they love. You get organic visibility when they share (and they do).
Branded Advocacy Posters: Personalized “I’m attending” or “I’m speaking” posters are generated automatically—no designer needed. Attendees become your event’s marketing army.
AI Avatar Check-Ins: We turn event check-ins into an experience. Attendees can generate personalized, branded avatars on the spot—fun, shareable, and sponsor-friendly.
We’ve tested this at over 2,000 events and seen a 3x increase in organic social reach for organizers. Event marketers and sponsors love it because it amplifies visibility without paid ads.
We’re event tech folks trying to make photos and moments work harder—organically.
Would love your feedback!

10. Show HN: Anthropic's MCP Server Directory
URL: https://glama.ai/mcp/servers
Author: punkpeye
Description: I started this project because I believe MCP has the potential to transform how AI models interact with external resources, but the ecosystem is still very fragmented. There's no central place to discover and compare all the server implementations available, which makes adoption and experimentation harder for developers.
I initially built the GitHub repo awesome-mcp-servers (https://github.com/punkpeye/awesome-mcp-servers/), and it's been amazing to see the community contribute to it. Now, I'm taking it further with a directory that automates many tasks—introspecting servers to determine the tools, resources, and prompts they provide, inferring required configurations, and checking dependencies for vulnerabilities. These features are designed to make it easier for people to trust and use these servers in production environments.
While an open-source protocol is fantastic for innovation, I also think we need a centralized channel for addressing critical issues like security vulnerabilities, dependency management, and user support. My hope is that this directory not only grows with help from contributions, but also becomes a trusted resource for anyone entering the MCP space. If you're working on MCP servers or are interested in the project, I'd love to hear your thoughts!

14. Show HN: Repocheck – a CLI tool to get an overview of your local Git repos
URL: https://github.com/bevane/repocheck
Author: skybar1
Description: I built a CLI tool that lists out all the local git repos within a directory in an easy to read table format including relevant information such as last modified date and the status of branches in the repo, along with whether it is synced with remote or not.
It also includes a bunch of flags to get exactly what you want in the format you want.
I got this idea as I was trying organize the large amount of local git repos I had. I also found it particularly useful when traveling since I use a different device. In these cases, it is really helpful to know which local git repos I forgot to push commits or have fallen behind the remote version.
Hope you find it really useful, let me know if you like it and also if you have any feedback for it!

15. Show HN: I Built a Groth16 ZK-Proof Verifier from Scratch Using Rust
URL: https://github.com/Dyslex7c/groth16-zkSNARK
Author: furfural
Description: I've always been fascinated by cryptographic principles, so I decided to dive deep into zero-knowledge proofs and implement a Groth16 proof verifier entirely in Rust. This project validates cryptographic proofs and demonstrates how succinct, verifiable computations can be achieved.
Using Rust's powerful libraries like arkworks, I implemented pairing checks, public input commitments, and proof validation logic while ensuring the code remains modular and efficient.
I handled the complexities of affine group operations, scalar multiplications, and optimized public input verification to make this a practical ZK verifier.
Let me know what you think! Happy to answer questions about the design, challenges, or ZK cryptography in general.

19. Show HN: Fun Elo-based leaderboard for games
URL: https://www.shmelo.io/demo
Author: itsikap
Description: Hi HN,
I built a leaderboard app to track rankings for my Catan group. It’s based on the Elo ranking system—the same system used in chess.
Everyone starts with 1100 points, and your score changes based on game results. Beating a stronger player earns you more points.
Turns out, the "elo" system isn’t just for chess. It works for any competitive game. We’re now using it for a variety of board games, and even for padel, and tennis.
Recently, I decided to open it up to the public.
You can give it a try — it’s free.

25. Show HN: A CLI Tool to Streamline Your Job Hunt as a Software Engineer
URL: https://github.com/angelplusultra/job-shell
Author: angelplusultra
Description: I built a CLI tool designed to streamline job hunting for software engineers. You can manage your job search more effectively by populating your professional connections and tracking companies of interest. Once set up, you can deploy it to a server to continuously scrape new job postings and share them directly to a Discord channel via free webhooks. This makes it easy to stay updated on relevant opportunities in real-time.
Why I made this?:
LinkedIn sucks, their email blasts are often spammy and filled with irrelevant listings. On top of that, if you’re relying solely on mainstream platforms like LinkedIn or Indeed, it’s nearly impossible to be first in line for a newly posted opportunity. It scrapes company job boards directly, ensuring you’re notified of opportunities the moment they go public.
Still making improvements everyday but you can give it a try using Homebrew (macOs) or install via Cargo (windows, linux). Appreciate any feedback!

Built with React, Next.js, Framer animations, Electron, and Rust for processing. Initially, it was fully browser based using Rust WASM, but even that was slow and made user onboarding difficult. After converting it to a Mac app, processing became 160x faster. All processing happens locally on your Mac for privacy & security - only encrypted story data leaves your device.

URL: https://apps.apple.com/me/app/aehr/id6451382928
Author: as_osipov
Description: I made this app for myself, but it's probably worth sharing.
When I tried to find a nice app that I could use to check air quality multiple times a day, I was shocked. All of them looked boring with traffic-light coding and overcrowded with unnecessary data. On top of that, they either contained ads or required payment.
I didn't want to use any of those apps every day, so I thought, "Well, how hard could it be?" and accepted the challenge. I expected to finish development in a month, but since I'm a designer and don't normally program apps, I had to learn Swift on the go. This required a month more than I expected.
In my designs, I'm usually way too focused on efficiency. Since this was my personal project, I wanted to experiment, so I didn't use standard controls or color coding.
Inspired by avant-garde style, I used forms and movement to convey air quality, as well as an asymmetrical layout and overflowing visualizations. I enjoy using the app, and I hope you will, too.

40. Show HN: ChatKeeper – Sync Your ChatGPT Conversations to Local Markdown Files
URL: https://martiansoftware.com/chatkeeper/
Author: martylamb
Description: Hi HN,
I wrote a tool to scratch my own itch and decided to make it available to others.
It's called ChatKeeper[0], and it syncs your ChatGPT export files to local Markdown files. This allows for easy and permanent local storage, searchability, and integration with note-taking applications like Obsidian (which I use). If you sync again after continuing conversations, ChatKeeper will find your conversation files — even if you've moved or renamed them — and update them in place, so you can reorganize them to your heart's content.
Many of my conversations have some lasting value, e.g. for reference or as part of a larger project. I've been around long enough to be distrustful of the long-term availability of anything online, so I want backups, and the best backups are useful ones (e.g. rather than the blob of json in a zip file that ChatGPT exports). And I often found myself wanting to access and reference them within Obsidian where I track lots of projects and thoughts. ChatKeeper has been incredibly helpful for my own workflow.
ChatKeeper is free to try with no registration needed (free version limited to 30 conversations to give you a sense of its results and its usefulness for you). The full version follows a shareware-like model at a modest one-time price, which includes all updates for a year and will continue to run without limitations forever. The world needs fewer subscriptions.
As for technical background, ChatKeeper is written in pure Java and compiled to native code using GraalVM's native-image tool. I build it for Linux, Windows, and macOS x86_64 on my Fedora 40 Linux desktop, and for macOS arm64 using an on-demand M1 instance from Scaleway. Downloads are stored in Cloudflare R2, purchases are handled through Paddle, and license generation happens on a webhook callback from Paddle to a service I built using Javalin running on fly.io. It's an unusual enough setup that I'm thinking about writing a blog post about it if I can make it interesting.
Ongoing updates will be needed as long as ChatGPT keeps adding new features - and they've been on a tear this month with their "12 days of OpenAI"[1]. Their export format is not documented (as far as I have been able to find), so every new feature results in a mostly fun reverse engineering puzzle. Canvas and search are two new features that I just added support for.
I hope ChatKeeper is useful to you, too, and I'd love to hear your thoughts on it, including how you might use it or any suggestions for improvement. I've been writing Java code since the late 90s including some open source tools that have had some impact, but this is my first "indie" product.
Please check it out at <https://martiansoftware.com/chatkeeper>!
Thanks!

41. Show HN: Search engine that helps Shopify stores sell more
URL: https://merchant.searchagora.com/
Author: pencildiver
Description: Hi HN! Agora is a search engine for e-commerce products. We've indexed 4 million products sold on 8,100 Shopify and WooCommerce stores and made them easy to purchase with a single cart transaction. Think of a decentralized Amazon.
I originally launched Agora as a side project here on HN to find a pair of red shoes for my wife last Christmas. I quickly realized that some of the best products on the internet are sold by small online stores that struggle to get the same visibility as large retailers. I started Agora on a mission to solve this problem. If you sell the best pair of red shoes in the world, customers should be able to find it.
We recently built a merchant dashboard that helps Shopify and WooCommerce merchants sell more on our search engine. Agora Merchants connects to your existing e-commerce store without any painful setup required and helps you track your store's performance on Agora. We don't take a commission of sales, orders are routed to your existing point of sale system, and inventory is automatically uploaded and refreshed. We do this with a combination of crawlers and AI agents.
So how is this different than Amazon? Both Amazon and Agora give network effects to stores (i.e. if you're searching for red shoes from one store, you may also want to buy a red dress sold by a different store). The key difference with Agora is that you continue selling on your existing e-commerce store, without having to manage inventory and payouts on another platform. This creates a magical experience for our merchants that saves them hundreds of hours. We believe in a future where merchants can sell however they want, we just bring them more customers.
I'd love your feedback!

43. Show HN: Build Internal Tools in Minutes Using Plain English Requirements
URL: https://genatron.ai
Author: tommy_axle
Description: We built a way to go from requirements to a fully working admin panel/internal tool -type application within minutes. As a user you provide the various entities and their relationship plus any reports or dashboard widgets and it will generate it for you.
The problem with existing no code tools is that you still need to spend a lot of time building after figuring out what is needed (a problem of its own). Being able to focus on what is needed means you can build faster than designing, dragging, dropping, configuring.
What can you describe? Everything from tables, field types, relationships between tables and columns/fields, role-based access restrictions (RBAC), reports, dashboard metrics, bar/line/pie charts, lists.
This is made possible by fine-tuning Llama 3.1 to convert requirements into specs and code. Applications evolve over time and this means that the model has to be predictable between versions to ensure that the data/schema migrations can be generated cleanly, as well as provide any errors and warnings related to the requirements or data loss.
For non-developers this can be a huge time-saver since you don't have to use any additional developer resources. For developers it can be a great way to get 80+% of the way for complex apps (it's like super-scaffolding). Generated apps can be fully evaluated before purchase. A full git repo containing the back-end, front-end, migrations, etc. is the output of the entire process.
Currently the generated code base is TypeScript, JavaScript, React, Next.js but the capability is there to generate different stacks because of the approach taken to not go directly to code when fine-tuning.
Brought to you by the team at Red Axle (https://redaxle.com)
Check out the video at https://youtu.be/rPppwB4jPlQ for a smaller app.
We look forward to your thoughts. Does building apps this way make sense for the super savvy HN crowd?

47. Show HN: Mapdown creates a sitemap for your Markdown files
URL: https://github.com/codazoda/mapdown
Author: codazoda
Description: I have a handful of websites built, automatically, from Markdown files. I don't always link to those on the site but I do want them to show up in search engines. So, I built Mapdown to generate the sitemap.xml file for me.
I built this and wrote the documentation in a few hours but I think it's fairly complete. Still, I haven't spent a lot of time tuning it. I've already started to use it on my own sites.

50. Show HN: Built something to tell my designer my thoughts clearly
URL: https://app.getcreatr.xyz/sign-up
Author: kartik0204
Description: I always used to have disagreements with my designer because he wasn’t clear about what I wanted him to build. Then, when he built something, I would ask him to redesign it. He would tell me that if I had been clearer from the start, he wouldn’t have had to scrap his previous version. Let me know if this helps you as well ?

54. Show HN: CheckoutLink – Turn your Instagram posts into a Storefront
Author: guzfernandez
Description: Why I built CheckoutLink: As a small business owner and creator, I noticed how challenging it can be to sell directly on Instagram without a website. Many sellers like me rely on DMs or clunky solutions, which can make managing sales and payments a headache. I wanted to simplify the process by turning my Instagram into a fully functioning storefront, quickly and effortlessly.
What CheckoutLink does: Turn Instagram posts into shoppable links—sell directly through DMs or bio links. Manage products, buyers, sales and payments from one simple dashboard. Sync your PayPal or Stripe account to get paid instantly. Quick setup with no coding or website required.
I'd love to hear your thoughts, feedback or any suggestions you have to make CheckoutLink even better. Feel free to ask me anything! Thank you so much for your support and I hope CheckoutLink can help you grow your business as well!

55. Show HN: WindChime a Family Task Manager
URL: https://www.windchime.app
Author: sillypuddy
Description: WindChime is a productivity app for families. It allows you to send todos to each other and share relevant family contacts. For example: the pediatrician, the plumber, or the address of your kids friends for dropoff and pickup.
Running a family takes coordination to figure out who is doing what and when. WindChime is an app built to make that a little easier.
It automatically sends notifications when you make a task request, and you'll get a notification when the task is complete so you don't have to follow-up to find out if something is done.
Current contact and todo apps create information silos necessitating messaging contacts and task requests back and forth. WindChime reduces the friction of coordination by making the information available across everyone's phones (parents, childcare, kids).
Built by two dads who want great apps for their family life.
