TL;DR
T3 Code is an open-source app that brings multiple AI coding agents into one workspace, while users keep their existing provider accounts and subscriptions. It can give each task a separate Git branch and let users review and open pull requests from the same interface. The project is young, and its reported user count has not been independently verified.
T3 Tools’ T3 Code brings several AI coding agents into a shared workspace, where developers can run tasks, review code changes and manage Git branches without replacing their existing provider accounts. The free, open-source app is aimed at developers juggling multiple coding tools; its makers say it works across desktop, web and mobile, with the agents running on a machine the user chooses.
T3 Code is not itself an AI model or a replacement for the software harnesses that give coding agents access to files and commands. The project’s FAQ says it uses harnesses users have installed and adds a common interface over them. Its homepage describes it as an “open-source control plane for coding agents.” Listed integrations include Claude Code, Codex, Cursor, Grok Build, OpenCode and Google’s Antigravity. The GitHub installation guide listed 10 providers on November 8, 2026, including Kiro, Pi, Muse Code and fx.
Users sign in through the individual providers, which continue to bill them under their existing plans. T3 Code says it does not resell tokens; that means the app adds no separate token allotment, not that provider limits or charges disappear. Its usage page combines activity across agents, but the documentation says cost figures are API-equivalent estimates, not a user’s actual subscription bill.
A task can be started in a separate worktree, giving its thread a distinct working folder and Git branch. Users can then inspect the changes and use the app’s Git actions to commit, push and open a pull request. The project also says users can switch agents mid-thread. It transfers some conversation context, but its documentation says the original agent’s internal reasoning, tool state and attachments do not carry over.
Infographic 01 · One surface, your own plans
Your subscriptions, one workspace
T3 Code puts the coding agents you already pay for into one interface. It orchestrates them; your provider bills you as before.
It does not resell tokens. You keep paying your AI providers as you do today, and your plan limits stay as they are.

Keeping Multiple Agent Tasks Separate
For developers who use more than one coding agent, a shared interface could reduce the work of switching between apps and tracking which tool changed which files. Separate branches and worktrees may also make it easier to run tasks in parallel, while a common diff view gives users one place to inspect proposed changes before they are committed or sent for review.
The distinction is that T3 Code organizes access; it does not provide the underlying models or waive the rules of the services being connected. Its practical value depends on whether a developer already has multiple agents to coordinate and whether the shared workflow fits their team’s review practices. Someone satisfied with one coding tool in one terminal may have little reason to add another layer.

AI coding products often combine a model with a harness that lets it inspect project files and run commands. T3 Code positions itself outside that pairing: it connects to tools already installed or authorized by the user and presents their work through a common surface. The project says agents run on a chosen machine, such as a laptop, home desktop or server, while other devices can act as remote controls.
The project lists desktop apps for macOS, Windows and Linux, along with a web app, command-line server and mobile apps for iOS and Android. T3 Code is available under the MIT open-source licence and costs nothing to use, according to its FAQ. Its GitHub repository had about 52,000 stars on November 8, 2026. The project’s website also claims more than 500,000 developers use it, but that figure could not be independently checked in the source material.
““The open-source control plane for coding agents.””
— T3 Code homepage
The source material does not provide independent testing of T3 Code’s reliability, security, performance or compatibility across the listed providers. It also does not establish whether every integration supports the same features or behaves identically. The claim that more than 500,000 developers use the app is attributed to its website and has not been independently verified.
Provider terms, authentication requirements and plan limits remain in force. The source says new threads start in full-access mode unless users change the default, but it does not detail the permissions or safeguards available for every provider. Developers should check the project’s current documentation and their providers’ terms before using it on sensitive code. The version identified in the material, 0.1.7, was released November 4, 2026, so features and behavior may change as the project develops.
Check Version and Provider Support
The immediate next step for prospective users is to check the current installation guide for supported providers, operating systems and sign-in instructions. They can then decide whether the shared workflow is useful for their own projects, particularly if they want tasks separated into worktrees or access to agents from more than one device.
Further updates will depend on the project’s development and on changes to the connected coding tools. The source material does not name a scheduled release or announce a specific next milestone. Users should check the project’s GitHub repository and documentation for changes to version, integrations and access settings.
Key Questions
Does T3 Code provide its own AI coding model?
No. T3 Code provides a shared interface for coding agents users already have installed or can connect. The project says it does not supply the models or harnesses themselves.
Do users pay T3 Code for tokens?
The app is described as free and does not resell tokens. Users continue to sign in to and pay their AI providers under their existing plans; those plans’ limits still apply.
Can separate coding tasks use separate Git branches?
Yes. The project says a thread started with a new worktree can receive its own working folder and Git branch. Users can review changes and use the app’s Git actions to commit, push and open a pull request.
Does switching agents preserve the entire conversation?
No. T3 Code says it transfers relevant conversation history, with longer threads condensed to selected turns and activity. The previous agent’s internal reasoning, tool state and attachments do not carry over.
Is T3 Code useful for someone who uses one coding agent?
It may be less useful if a developer is content with one tool in one terminal. The project’s described benefits focus on coordinating multiple agents, running tasks in parallel and accessing work from several devices.
