TL;DR
T3 Code is an open-source workspace for using AI coding agents such as Claude Code, Codex, Cursor and others through one interface. It uses users’ existing provider accounts rather than selling tokens, and offers separate Git workspaces for tasks. The project was at version 0.1.7 on Nov. 4, 2026; its adoption and some product claims have not been independently verified.
T3 Code, an open-source project from T3 Tools Inc., brings several AI coding agents into one workspace, where developers can manage tasks, review code changes and carry out Git operations. The app is designed to work with users’ existing agent accounts rather than sell access to a new model, an approach aimed at developers who use multiple coding services and want a shared place to coordinate them.
The project’s website describes T3 Code as a control plane for coding agents. According to its documentation, the software uses agent tools and harnesses that users already have installed; it provides a common interface rather than its own coding model. The source lists support for services including Claude Code, Codex, Cursor, Grok Build, OpenCode and Google Antigravity. A GitHub installation guide listed 10 providers on Nov. 8, 2026, including Kiro, Pi, Muse Code and fx.
T3 Code is described as free and licensed under MIT. Its site says it does not resell tokens: users authenticate with their provider accounts, and provider billing and plan limits continue to apply. The project also allows separate provider instances using API keys, according to its FAQ. A usage page brings together estimates across agents, but the documentation cautions that its cost figures are API-equivalent estimates, not a statement of what subscribers are billed.
The project says users can give each thread its own Git branch and working folder, allowing tasks to run separately. From the same interface, users can inspect changes and commit, push or open a pull request. T3 Code also supports switching providers within a thread. Its documentation says short conversations can transfer intact; longer conversations may be condensed, and the new agent does not inherit the prior agent’s internal reasoning, tool state or attachments.

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 Workspace for Multiple Agents
For developers who pay for or otherwise use several coding agents, a shared interface could reduce the work involved in moving between separate apps, terminals and histories. A common diff view and Git workflow may also make it easier to compare agents’ output and keep parallel tasks from changing the same working folder. Those are product goals described by the project, not independently measured productivity gains.
The subscription model is also relevant: T3 Code says it adds no token resale or separate usage plan. That may make it easier to try alongside existing tools, but it does not remove provider costs or account restrictions. The value will depend on how well the supported agents work through the shared interface and whether users are comfortable with its permissions and workflow.

How T3 Code Fits the Agent Stack
AI coding products commonly combine a model with a harness: software that gives the model access to files, commands and other tools. T3 Code’s FAQ says it supplies neither of those pieces. Instead, it places an interface over harnesses users have installed and authenticated. That distinction matters because T3 Code depends on the behavior and availability of the underlying services; it is not a replacement model or a promise of free access to them.
The source describes desktop versions for macOS, Windows and Linux, as well as a web app, command-line server and mobile apps for iOS and Android. Agents run on a machine selected by the user, such as a laptop, home desktop or server; other devices can act as remote controls. The project’s GitHub repository had about 51,990 stars on Nov. 8, 2026, according to the source. The site also claims more than 500,000 developers use the product, a figure the source says it could not independently verify.

Early Release, Open Questions
T3 Code was at version 0.1.7 on Nov. 4, 2026, making the cited release an early version. The source does not provide independent testing of the supported integrations, reliability, security practices or claims about how much time the workspace saves. The reported figure of more than 500,000 developers is a company claim that the source says it could not verify.
Users should also distinguish T3 Code’s own features from each provider’s terms and capabilities. The source says existing plan limits remain in force, but does not establish that every provider permits every described workflow or account type. It also reports that new threads begin in full-access mode unless users change the default. The practical scope of that access, and how settings differ across platforms and agents, should be checked in the current documentation before use.
Context transfer between agents has limits: the documentation says internal reasoning, tool state and attachments do not move to the new provider. The source does not say how every agent handles every conversation or whether all integrations have identical behavior.
What Developers Should Check
The next step for interested developers is to consult T3 Code’s current installation and security documentation, confirm that their preferred agents are supported, and review provider terms before connecting accounts. They can then test the workspace on a low-risk task, check the permissions used by new threads and verify the resulting diff before committing or opening a pull request.
The project’s documentation and release history will show whether it adds providers, changes default access settings or addresses early-version limitations. The source does not identify a scheduled release or a specific upcoming milestone, so the timing of further updates is unclear.
Key Questions
What is T3 Code?
T3 Code is an open-source workspace that puts supported AI coding agents behind one interface. According to its FAQ, it uses existing agent harnesses rather than providing its own model.
Does T3 Code include AI model access?
No. The project says users sign in with their existing provider accounts or configure separate API-key providers. Provider billing and usage limits still apply.
Which coding agents does it support?
The source lists Claude Code, Codex, Cursor, Grok Build, OpenCode and Google Antigravity, among others. A GitHub installation guide listed 10 providers on Nov. 8, 2026; support can change, so users should check the current guide.
Can T3 Code run tasks in parallel?
The project says a thread can use its own Git branch and working folder, which is intended to separate tasks. Users should still review changes before merging or opening a pull request.
Is T3 Code ready for every development workflow?
The cited release was version 0.1.7, and the source does not provide independent reliability or security testing. Developers should review current documentation, provider terms and access settings before using it on sensitive projects.
