TL;DR
T3 Code brings multiple AI coding agents into a shared interface, using the providers’ existing subscriptions rather than reselling model tokens. Its workflow includes separate branches for tasks and tools for reviewing changes and opening pull requests, but users remain subject to provider limits and should check the project’s permissions and setup.
T3 Tools’ T3 Code is an open-source app for running multiple AI coding agents through one interface, with separate Git branches for tasks and review tools intended to carry work through to a pull request. The project is aimed at developers juggling agents such as Claude Code, Codex, Cursor and Antigravity; it does not provide a new model or replace the subscriptions users have with those providers.
According to the project’s website and documentation, T3 Code works as a shared control surface for coding agents that users have installed and authenticated with their providers. The project says it supports Claude Code, Codex, Cursor, Grok Build, OpenCode and Google’s Antigravity. Its GitHub install guide listed 10 providers on November 8, 2026, including Kiro, Pi, Muse Code and fx. The named agents and availability may vary by guide or version.
The app is described as free and open source under the MIT licence. Users sign in through each provider’s own method, and those companies continue to bill them under their existing plans. T3 Code says it does not resell tokens or impose its own quota caps; provider plan limits and terms still apply. The project also offers a usage view, but its documentation describes cost figures as API-equivalent estimates, not a statement of what users owe under a subscription.
Each task can be given its own Git branch and working folder through a new-worktree option, allowing tasks to run separately. Users can inspect the resulting diff and use the app’s Git actions to commit, push and open a pull request. T3 Code also says users can switch agents within a thread, though the handoff does not preserve everything: its documentation says internal reasoning, tool state and attachments from the previous agent stay behind.

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.

One Interface for Parallel Coding Work
T3 Code’s pitch addresses a practical problem for developers who use multiple coding assistants: separate apps and terminals can make it harder to track which tool changed which files or to compare outputs. A shared thread view and branch-per-task workflow could make parallel work easier to inspect and reduce the need to move manually between interfaces.
The app does not remove the cost or limits of using several providers. Instead, it offers a common layer for tools developers already use. That distinction matters for teams weighing whether another app will simplify their workflow: the main potential benefit is coordination and review, not access to cheaper tokens or a new coding model. Its usefulness will depend on how well the supported agents integrate with a developer’s setup and how much trust they place in the app’s access to their projects.

How T3 Code Fits Existing Tools
AI coding products often bundle a model with software that gives it access to files, commands and other development tools. T3 Code describes itself as neither a model nor an agent harness; it sits above installed tools and presents them through one interface. The project calls that role an “open-source control plane for coding agents.”
The described setup spans a desktop app for macOS, Windows and Linux, a web interface, a command-line server and mobile apps for iOS and Android. The agents run on a machine selected by the user, such as a laptop or server, while other devices can connect to it. The source material reports 51,990 GitHub stars on November 8, 2026; the project also claims more than 500,000 developers use it, a figure the source says it could not independently verify.

Limits, Permissions and Project Maturity
The source material describes T3 Code as a young project: it identifies version 0.1.7, released or listed November 4, 2026. It does not provide independent testing of the app’s reliability, security, or performance across all listed agents and operating systems. The project’s claim of more than 500,000 developers is also not independently verified in the supplied material.
Users should not interpret “no quota caps” as unlimited access: provider terms, rate limits and plan allowances still apply. The material also says new threads begin in full-access mode unless users change the default. It does not detail the permission model, data handling, or how every provider’s authentication and access behave in practice. Those points should be checked in current documentation before connecting the app to sensitive code or using it in a team workflow.
Agent handoffs have limits as well. T3 Code says a new provider can receive selected conversation context, but not the previous agent’s private reasoning, tool state or attachments. It is not clear from the source material how consistently this works across long conversations or each supported provider.
Check Current Support Before Installing
Developers considering the app can check T3 Code’s current release notes, provider installation guide and security documentation before installing it. Provider support and setup instructions may change as the project develops, so the guide for the version being used is more useful than assuming every listed agent works in the same way.
For a first test, users can try a non-sensitive repository, verify which permissions are enabled, and review a branch’s diff before committing or opening a pull request. The source material does not announce a specific upcoming release or roadmap date; future changes and support updates remain unannounced.
Key Questions
Does T3 Code include its own AI model?
No. T3 Code presents itself as an interface for coding agents users already have installed, rather than a model provider or agent harness.
Do users need to pay for T3 Code?
The project says the app is free and open source under the MIT licence. Users still pay for their existing AI provider plans, which retain their own terms and limits.
Which coding agents does it support?
The project names Claude Code, Codex, Cursor, Grok Build, OpenCode and Antigravity. Its GitHub install guide listed 10 providers on November 8, 2026, including Kiro, Pi, Muse Code and fx; check the current guide for supported versions and setup details.
How does T3 Code handle separate coding tasks?
Its new-worktree option can give a thread its own Git branch and working folder. Users can inspect changes and use Git actions to commit, push and open a pull request.
Does switching agents preserve the whole conversation?
Not necessarily. T3 Code’s documentation says a handoff can carry selected conversation context, but the previous agent’s internal reasoning, tool state and attachments do not transfer.
