T3 Code
An AI-powered coding tool for developers that supports an orchestrator mode for managing and coordinating AI agents in the execution of complex development tasks.
Timeline (last 90 days)
T3 Code is an open-source AI coding assistant maintained by three part-time developers that can manage multiple AI subscriptions and tools.
T3 Code has received 27,000 GitHub stars and has 516 contributors.
T3 Code users need to provide their own compute resources, and there is no official cloud service; computer-use functionality is not yet built in but can be achieved indirectly through tools such as Codex.
Theo claims that T3 Code uses 100 times less data than Codex when switching threads and works smoothly even on poor mobile networks.
The ACP (Agent Client Protocol) registry is the indexing mechanism T3 Code uses to discover and connect third-party agent tools, enabling different agents to be identified, configured, and invoked in a unified way.
Running `npx t3` in the terminal starts the T3 Code service and exposes its capabilities via WebSocket, while also hosting a minimal web app.
All of T3 Code's operations go through a WebSocket server rather than sending commands directly to the terminal or using Electron's RPC calls, which makes remote control simple.
T3 Code's orchestration layer is implemented as a flexible MCP, allowing agents to communicate with each other, manage other threads, and be controlled remotely via external tools (such as an iMessage bot).
T3 Code has built-in support for Codex, Claude, Cursor, Grok, OpenCode, Antigravity, and MuseCode, and is compatible with tools such as AMP, Klein, and Copilot in the ACP registry.
T3 Code is about to reach 550,000 users and 140,000 weekly active users.

50%UnverifiedWhen integrating fx in T3 Code, the models and skills the user already uses in fx are compatible, requiring no reconfiguration.
50%UnverifiedThe integration path is: first install fx and set up a model provider, then download T3 Code and add fx under "Providers > Add provider" in settings.
50%UnverifiedT3 Code is an open-source control plane for coding agents that allows developers to add agents such as fx as providers for coding sessions.
50%UnverifiedT3 Code provides built-in provider support for fx, including two modes: Supervised and Auto.
