It's finally here.

T3 Code is a new free, open-source desktop and web application for managing AI coding agents, built as an alternative to the Codex app. Created by Theo and Julius, it focuses on high-performance parallel agent workflows using worktrees, and wraps official CLI harnesses (Codex CLI, with plans for Claude Code, Cursor, Gemini) rather than building a custom agentic framework. The alpha is available now via a desktop installer or `npx t3` command. Key differentiators include multi-project parallel threads, one-click GitHub PR creation, and no lock-in to a single model provider. The project is early-stage, not yet accepting external PRs, but welcomes issue feedback.
