T3 Code

T3 Code is a minimal web GUI for coding agents. Currently Codex-first, with Claude Code support coming soon.

Notable features

• Codex-first local coding workflow with a web UI and desktop app.
• Orchestrate task and thread management for longer-running agent work.
• Local Error Inbox for collecting actionable MCP, provider, websocket, and browser diagnostics and promoting them into Orchestrate tasks.

How to use

Warning

You need to have Codex CLI installed and authorized for T3 Code to work.
