1Code – Open-source Cursor-like UI for Claude Code▲75
Hi, we're Sergey and Serafim. We've been building dev tools at 21st.dev and recently open-sourced 1Code (https://1code.dev), a local UI for Claude Code. Here's a video of the product: https://www.youtube.com/watch?v=Sgk9Z-nAjC0 Claude Code has been our go-to for 4 months. When Opus 4.5 dropped, parallel agents stopped needing so much babysitting. We started trusting it with more: building features end to end, adding tests, refactors. Stuff you'd normally hand off to a developer. We started running 3-4 at once. Then the CLI became annoying: too many terminals, hard to…

Codestat.dev – Stats from 2M open-source repositories▲63
Hi HN! This is a little site I put together while learning the Elm language as part of a hackathon at my work, I thought you might enjoy it. Be sure to click the `(source)` buttons next to the graphs: you can edit them interactively & write your own queries against the entire data set. The syntax isn't well documented yet, but you can probably get the general idea pretty quickly based on the examples there. If you like it, have questions, etc. let me know! If folks think this is cool, maybe I can get it turned into a legit project. :)

I wrote a beginner SRE book, and it's free today▲31
Hello! I wrote an introductory SRE Book: Site Reliability Engineering Tidbits and it's free today! These are short fun chapters about SRE, monitoring, debugging, observability, and resiliency. This book aims to provide hands on examples of implementing a number of concepts described in Google's SRE books. It also describes how i've seen SRE concepts impact some of the organizations I've worked in. A couple chapters are hands on debugging exercises going through the process of debugging applications based on data. I'm excited because every chapter describes something that I've done in paying…
