T3 Code

T3 Code is a minimal web GUI for coding agents (currently Codex and Claude, more coming soon).

How to use

Warning

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

npx t3

You can also just install the desktop app. It's cooler.

Install the desktop app from the Releases page

Some notes

We are very very early in this project. Expect bugs.

We are not accepting contributions yet.

Git conflict setup

This repo includes a local Git setup command to reduce noisy merge conflicts, especially around bun.lock.

bun run git:setup-merge-tools

That command configures this checkout to:

• use diff3 conflict markers
• enable rerere
• treat bun.lock as generated and prefer the incoming version during merges
• enable mergiraf for all files if it is installed on your PATH

After resolving dependency manifest conflicts, regenerate the lockfile with:

bun run lockfile:refresh
