Coda is an "agent harness control surface". It enables control of the agents on your machine from a web, desktop, or mobile client.
Works with your subscriptions on Claude Code, Codex, Cursor, Grok Build, OpenCode, and Google Antigravity. If they're set up on your computer, Coda can control them.
Note
Coda is a fork of T3 Code. It is not published to any package registry — you run it from this checkout. It keeps its own identity everywhere it touches your machine, so it can run side by side with an installed T3 Code:
| T3 Code | Coda | |
|---|---|---|
| Data directory | ~/.t3 |
~/.coda |
| Environment variables | T3CODE_* |
CODA_* |
| Desktop bundle ID | com.t3tools.t3code |
com.coda.app |
| Deep-link scheme | t3code:// |
coda:// |
| Checkpoint git refs | refs/t3/checkpoints |
refs/coda/checkpoints |
| Worktree branch prefix | t3code/ |
coda/ |
| CLI binary | t3 |
coda |
Warning
Coda currently supports Codex, Claude, Cursor, Grok Build, OpenCode, and Antigravity. Install and authenticate at least one provider before use:
- Codex: install Codex CLI and run
codex login - Claude: install Claude Code and run
claude auth login - Cursor: install Cursor CLI and run
agent login - Grok Build: install Grok Build CLI and run
grok login - OpenCode: install OpenCode and run
opencode auth login - Antigravity: enable it in Settings, then use Install Antigravity and Sign in with Google. No CLI is required.
Install the toolchain and dependencies (see Install vp below), then:
vp i # install dependencies
vp run dev # server + web app, hot-reloading
vp run dev:desktop # Electron shell instead of the browserThe [dev-runner] line printed at startup tells you the real ports and data directory. The web app
requires pairing — open the pairing URL it prints, not the bare origin.
