T3 Code puts your local coding agents behind one console, reachable from phone, web and desktop
Synopsis
T3 Code released an agent harness control surface that drives coding agents already installed on a user's machine from one iOS, Android, web and Electron desktop interface. It does not train a model or replace those agents: users must first install and authenticate at least one supported provider, such as Codex, Claude, Cursor, Grok Build, OpenCode, Antigravity or fx, and T3 Code then controls it. The project describes itself as very early, warns of bugs, and is mostly not accepting contributions.
Interpretation
Local coding agents gain a single operating entry point: T3 Code positions itself as an agent harness control surface that connects agents already configured on the user's computer to mobile, web and desktop interfaces. Users previously relied on existing options such as the Codex desktop app, Conductor, Claude Desktop and Cursor Glass; T3 Code's stated aim is to beat those on performance, remote readiness and openness. The checkable comparison is the support list: T3 Code states it can control Claude Code, Codex, Cursor, Grok Build, OpenCode, Google Antigravity and fx, provided each is installed and logged in on the machine.
The control surface is separated from the agents themselves: T3 Code runs a server on the machine, and the interfaces operate the existing local agents through that server, so the agents are not swapped out. Installation is split by platform: the install script is followed by running t3 to start the server and open the local web app, t3 service install keeps it running in the background, and the desktop app comes from GitHub Releases or package registries. Providers must be authenticated first, for example Codex requires installing the Codex CLI and running codex login, Claude requires Claude Code and claude auth login, and Antigravity is enabled in Settings and signed in with Google without a CLI.
Perspective
The demonstrated scope is controlling a supported agent through T3 Code's mobile, web or desktop interface after installing and authenticating at least one provider on the user's own machine; the project describes itself as very early and warns of bugs.
The project calls itself very early, warns that bugs are expected, and is mostly not accepting contributions, with only small fixes possibly considered; documentation lives in the repository's docs/ with no docs site yet.
