arpitbhayani's px0, a remote-first ultra-light IDE, released v0.17 and says users are migrating from Zed.
Key specs:
- Cold start <1ms, resident memory 20MB (VS Code: 1,440MB on the same tree)
- Fuzzy-finds across the Linux kernel's 95,710 files in 6ms; 280 languages tokenized natively
- Zero runtime deps — no Electron, no Node; runs in the browser, built for instant code navigation and review
- v0.1.7 makes git diff mode the default; GitHub integration is coming so you can view, review and edit PR diffs
- Works with Claude Code, Gemini CLI, Codex, Aider and more: hand edits to a coding agent and px0 reloads what moved
One-liner: run px0 . to open your git diff instantly in the browser — browsing/reviewing in px0, coding delegated to agents.
