T3 Code is a control layer for locally installed coding agents, with apps for mobile, web, and desktop so you can manage them remotely.
T3 Code describes itself as an "agent harness control surface": a tool for controlling coding agents that already run on your machine. It offers a mobile app, a web app, and an Electron-based desktop app, and it is designed to work with subscriptions and local setups for Claude Code, Codex, Cursor, Grok Build, OpenCode, and Google Antigravity. The README also emphasizes that the project is intended to be open and forkable.
The project aims to give people a better way to use coding agents, especially when they want remote access and a polished control experience. The README says the authors were not satisfied with existing options and wanted something performant, remote-ready, and fully open, with enough openness that others could fork it if the project drifts in the wrong direction.
At a high level, T3 Code connects to agent tools that are already installed and authenticated on your computer, then lets you control them through its own interfaces. The README says it can work with several supported providers once they are set up locally, and it also documents remote access, background service mode, source control integrations, permission modes, and MCP-based connections to outside agents. The exact internal implementation is not described in the README provided here.
It is gaining attention because it sits at the intersection of AI coding agents, remote control, and multi-platform access, which is a timely combination for developer tooling. The README highlights support for multiple popular agent ecosystems, mobile and web control, background-service operation, and a strong open-source/forkable stance, all of which are likely to resonate with people following the current agent tooling wave. The repository also shows substantial recent star growth in the metadata provided.
The README itself names Codex desktop app, Conductor, Claude Desktop, and Cursor Glass as inspirations or comparable references. It also points to direct vendor tools and CLIs such as Claude Code, Codex CLI, Cursor CLI, Grok Build CLI, OpenCode, and Google Antigravity, though T3 Code presents itself as the control layer over those tools rather than a replacement for them.
