Open-source certificate from GitHub activity
I built this as a small side project to learn and experiment, and I ended up with this! I used a subdomain from my personal portfolio, and everything else runs on free tiers. The project uses Nuxt, SVG, Cloudflare Workers, D1 (SQL), KV, Terraform, and some agentic coding with OpenAI Codex and Claude Code. What started as a joke among friends turned into a fun excuse to build something end to end, from zero to production, and to explore a few things I’d never touched before. I’d really appreciate any feedback or suggestions.

In plain words
This tool generates certificates based on GitHub activity, created as a learning project to explore full-stack development. Built with Nuxt, Cloudflare Workers, and D1 database, it runs entirely on free tiers from a personal portfolio subdomain. The project demonstrates end-to-end implementation using modern development tools including agentic coding assistance, designed for developers who want to visualize their GitHub contributions in certificate form.

I made a CMS that uses Git to store your data2022 · outstatic.com · ▲203I'm excited to finally launch Outstatic, an open source static website CMS that doesn't require a complicated setup or signing up to a third-party service! You can access the documentation here: Outstatic Documentation. I invite you to start by deploying our example blog to Vercel and giving it a try. I think you'll be pleasantly surprised at how easy and fun it is to use Outstatic. Please, let me know what you think. This is the first public version of the project and all feedback is welcome. If you dig the project feel free to leave a star on Github. I appreciate your support!

Git for AI AgentsMay 2026 · github.com · ▲129hi guys. been working on something i think is fundamentally missing in today's workflow with ai agents. vcs. i find myself struggling with questions that agents can't answer like "why did you do it?", "when did u delete this folder? why?", etc. or trying to /rewind (after a /compact...) or basically `bisect` to find when and why something was done by the agent in the current / previous session. just like git did for code, i think we are the same core capabilities with ai agents so... i developed an open source solution for that (currently supporting claude code) would love to…
Cptn.io – open-source integration platform2023 · cptn.io · ▲139Hi, I am Krishna Thota. I am building an open source integration and data platform(https://cptn.io). The product is MIT licensed and the repo is at https://github.com/cptn-io/el-cptn. I have started on my startup journey an year ago and launched a monitoring platform called DevRaven. Unfortunately the product did not takeoff as expected. That story is for another day. But during the course of building the product, I have built several integrations leveraging MQs and Cloud Functions. While building and deploying Cloud Functions for happy paths is easy, I had to…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
