Built on the goated T3 Code by T3 Tools.

V12Code is a minimal web GUI for coding agents (currently Codex, Claude, Cursor, and OpenCode, more coming soon).

V12Code brings the best coding-agent workflows into one fast, open-source app:

• Cursor-like chat drafts: Start a chat, switch away, and come back without losing what you wrote.
• Message queuing: Send follow-up messages while an agent is working and keep the next instructions ready to go.
• Codex-like tasks: Follow agent work as clear tasks instead of digging through a wall of output.
• Annotations and tasks: Select text from a response, turn it into a tracked task, and send it back to the agent with its original context.
• Richer tool-call details: See commands, file changes, results, and failures in useful, readable cards.
• Chat pinning: Keep important chats at the top of the sidebar so they stay easy to find.

npx v12code@latest

Tip: Use npx v12code@latest --help for the full CLI reference.

Install the latest version of the desktop app from GitHub Releases, or from your favorite package registry:

winget install V12Code.V12Code
