Theo & T3 Team
Open-source GUI for managing AI coding agents with your own API keys.
About T3Code
T3 Code is a free, open-source desktop application that acts as a unified front-end for AI coding agents. It connects to services like OpenAI's Codex and Anthropic's Claude Code using your own API keys (BYOK), providing a graphical interface for interactions that would otherwise happen in a terminal. No subscription fees — you only pay for your own API usage.
Key Features
Unified Agent Interface
Manage multiple AI agents (Codex, Claude Code, and planned support for Cursor, OpenCode, Gemini) from one interface.
Project-Based Threads
Organize conversations by project with persistent thread history that preserves context across provider switches.
Bring Your Own Key (BYOK)
Use your own API keys from OpenAI, Anthropic, or other providers. No proxy, no middleman, no extra subscription fees.
Three-Panel Layout
Left sidebar for repos, middle panel for threads, right panel for chat-style interaction with real-time tool calls.
