The open source workspace for your coding agents. Zeron runs Claude Code, Codex, OpenCode, Cursor, Antigravity, and more on your machines.

Used by developers from

Cursor Unsloth The Context Company

Runs what you already use

Zeron is not a new harness. It drives Claude Code, Codex, Cursor, Grok, Hermes and Pi — the same sessions and tools you use each day, in one fast native window on every device.

Three screens, one session

Sessions live on your machines, every device you own can pilot them. Start Claude Code at your desk, watch it from your phone, approve the diff from the couch. Nothing to hand off, nothing to re-open.

“Oh man, this is the best UI I’ve ever tried! For real. It feels really smooth. Typing, reading, everything. Really fast. Right now it’s my main UI for coding.”
