I’ve started building a domain-agnostic scientific data archive, inspired by the Protein Data Bank. It handles the deposition, validation, curation, storage, and searching of scientific data, with plugin interfaces for domain-specific components.

The goal is to accelerate AI-for-science efforts by making it easy for scientific organisations to spin-up professional-grade data infrastructure in a matter of days. “PDB-in-a-box”.

An agentic media player, intended as home media server for.. uhh.. seasonal vacation videos with subtitles. I've experimented a lot with different "levels" of AI automation, starting from simple workflows, to more advanced ones, and now soon to fully agentic.

Pretty good practice project! All written in Go with minimal dependencies and an embedded vanillja-js frontend built into the binary (it's so small it's negligable)

I'm building an app that takes a screenshot every hour from some news websites. It's is a small python script running on my raspberry pi 5 and for now I'm saving the images there. I'm planning to build a front-end app to explorer how each website changes over the course of a day, focusing only on the top of the landing page.

Still experimenting with data productivity tooling that doesn't rely on YAML. Been refocused on CLI tooling as a good interface for agentic use recently since Claude Code has gotten so good. Need to do some empirical evaluation on MCP/CLI success rates.

I’ve made AI browser that others do but having full control.

It was my weekend 1-day hackathon yesterday building Electron-based web browser connected with PlayWright MCP and local Codex as LLM backend.

Yes, you need to be ChatGPT Pro+ to use, because Codex has no usage fee unlike API Key.

GPT-5.1-Codex-Max can handle really complex web task without templating DOM. Codex-Mini is fast so you can pick models. It does my job applying task to any of recruiting sites with no interactions. (with persistent data store, which is currently disabled on published version)

I'm working on https://techposts.eu - Hacker News for Europe. Focused on all the interesting and exciting happenings in tech here, from AI to defence to deeptech, and posting the most interesting job openings too. Did you know Europe had two space launch startups? I didn't until I started this project! Feedback very welcome :)

Love to see EU specific. How do you get the jobs posts?

I recently open-sourced my first ever tool! and I'm super excited about it guys

It's an HTTP request replay and comparison tool in Go. You can replay real traffic, compare multiple environments, detect broken endpoints, generate HTML/JSON reports, and analyze latency

It’s currently at v0.4, so I’d love any feedback, suggestions, or ideas for improvements. (Be gentle, I haven’t used Go professionally, however it’s my main language for personal projects )

Here's the landing page too: https://www.replayer.online/

I created this simple stock management system. This was a good experience building an end to end product since I have been a front end developer all my life, building this has been an amazing experience.

Here is the github URL : https://github.com/codingbbq/stockflow

Appreciate any feedback on the application or review on the code..

Thank you

I've built a web app primarily for my Hiking Club but then my plan is to also sell it to others.

https://mojtim.ba/en/

'Vibe coded' this in about a week recently. The app is also available in English and has a demo account available.

I wrote about the building process on my Linkedin (https://www.linkedin.com/feed/update/urn:li:activity:7404469...)
