Profile

I made Buildermark to see exactly how much of my code is generated by my coding agents vs what I was writing by hand. For this project, it ended up being 364 agent conversations writing 94% of the code. Browse all of those here: https://demo.buildermark.dev/It matches edits by your coding agents (scans history in `~/.claude`, '`/.codex', etc.) with git commit diffs. It does formatting-agnostic matching to be robust against auto-formatting and reorganizing code. It's open source and local only, not even any analytics.Everything is automatic... just run the app, open the localhost:55022 frontend, and choose the project to import.It supports Claude Code, Codex, Gemini, and Cursor, so far.

Within the show hn launch space, the company focuses on its core offering rather than a broad product line.
