T3 Code
Open source (MIT) app that runs several coding agents in one place and lets them hand work to each other.
T3 Code is an open source (MIT) app. The repository is pingdotgg/t3code, and Theo posted the launch. It runs several coding agents, including Claude Code, Codex, OpenCode, Cursor, Grok, Pi, and more, in one place and lets them hand work to each other. You bring your own provider accounts. Provider setup and charges are separate. The README says it is early and to expect bugs. v0.1.3 stable was published on October 27, 2026. Theo's launch post lists a complete app redesign, sharing a thread with a guest in 2 clicks, and opening a thread loading 85% less data. The v0.1.3 release notes also say T3's agent instructions and tool copy were cut by 60% (PR #24850), MCP tool schemas were cut by a third with 18 tools merged into action tools (PR #25423), and follow-ups steer the running turn by default (PR #24718). v0.1.0 on October 15, 2026 made Orchestrator V2 stable: delegate_task lets an agent start child agents on any provider or model, a T3 Code MCP lets agents create, message, and interrupt threads, queued messages survive restarts, scheduled tasks, and ACP Registry agents.
