arpit_bhayani · x · 2026-09-24
px0, an open-source "IDE for humans and AI" focused on fast code review, has shipped v0.1.9. Running px0 <github-pr-url> opens any GitHub PR directly: scoped merge-base diffs, inline comments, reply threads, and commit/push fixes in place.
Key facts:
- Cold start <1ms, 20-30MB memory (10% of VS Code), no Electron/Node deps, browser-based single tab
- Indexes the 95,710-file Linux kernel in 370ms with 6ms fuzzy find
- Connects natively to 8 local coding harnesses (Claude Code, Gemini CLI, Cursor, Aider, etc.), turning agent edits + human review into a zero-latency loop
- Open source, 1k+ GitHub stars
Author arpitbhayani says once you use it to review across repos, you won't go back to other editors.
