T3 Tools’ T3 Code is a free, open-source app that brings coding agents such as Claude Code, Codex and Cursor into one interface. It uses the providers’ existing sign-ins and subscriptions, while offering task-specific Git branches and remote access. The project is at version 0.1.7, and its documentation says new threads start with full access unless users change the setting.
T3 Tools’ T3 Code brings multiple AI coding agents, including Claude Code, Codex and Cursor, into a single workspace, letting developers manage tasks and review code changes across tools. The free, open-source app uses users’ existing provider accounts and subscriptions; it does not sell a bundled model or replace the providers’ billing and plan limits.
T3 Code is designed to sit above the software that already runs each coding agent. Its FAQ describes it as neither a model nor an agent harness, but an interface for using harnesses developers have installed. The project calls it an “open-source control plane for coding agents.” Its homepage lists Claude Code, Codex, Antigravity, OpenCode, Cursor and Grok Build; the installation guide listed 10 providers on November 8, including Kiro, Pi, Muse Code and fx.
The project says developers authenticate with each provider on the machine running the agents. That can mean using a provider’s command-line login or signing in through T3 Code’s settings. The app says it does not resell tokens, and its own price is $0. Users continue to pay their providers, whose subscription terms and usage limits remain in force. T3 Code also supports separate provider instances using API keys or OpenRouter, according to its FAQ.
Each thread can have a dedicated Git branch and working folder. From the interface, users can review a diff and then commit, push and open a pull request. T3 Code supports desktop systems, a web app, a command-line server and mobile apps. The project says agents run on a chosen machine, such as a laptop, home desktop or server, while other devices can connect remotely. Its usage page combines activity across agents, but documentation says cost figures are API-equivalent estimates, not a statement of what a user owes under a subscription.
T3 Code brings agents together in one workspace
The free, open-source app connects coding agents through your existing provider accounts. Separate subscriptions, limits and permissions still apply.
One interface, existing agents
T3 Code coordinates installed tools; it does not supply a new model or replace provider accounts.
Bring agents together
Use Claude Code, Codex, Cursor and other supported agents in one workspace.
Keep provider billing
Sign in with existing accounts. Provider prices, quotas and plan terms remain in force.
Keep parallel tasks organized
Each thread can have its own branch and working folder.
Run an agent on a chosen machine and keep its work in a dedicated folder.
Inspect the diff, then use Git controls to commit, push or open a pull request.
Connect from other devices
The agent runs on a selected machine; other devices can connect remotely.
Check access before starting
The documented default gives new threads full access unless users change the setting.
- Review thread access mode and agent permissions.
- Confirm provider login and plan rules.
- Inspect changes before shipping; a shared interface does not verify code.
- Treat combined usage figures as API-equivalent estimates, not subscription invoices.
One Workspace for Agent Tasks
For developers who use more than one coding agent, a shared interface may reduce the work of switching between separate apps, logins and change-review processes. T3 Code’s per-thread branches and working folders are intended to keep parallel tasks apart, while its common diff and Git controls give users one place to inspect changes before shipping them.
The setup also makes it possible to use different agents on the same project, including asking one to review work produced by another. That may help teams compare outputs, though the app’s interface alone does not establish that one agent’s changes are correct or safe. Developers still need to inspect diffs and follow their usual review process.
The practical value depends on how someone works. The project’s own guide says it is aimed at people using two or more agents, running tasks in parallel or working across several devices. Someone content with one agent in one terminal may gain less. T3 Code adds a coordinating layer, while provider charges, quotas and terms remain separate.

How T3 Code Fits In
AI coding products often combine a model with a harness: software that gives the model access to files, commands and other tools. T3 Code’s stated approach is to use the harnesses already installed and provide a common interface over them. In practical terms, it is meant to coordinate existing tools rather than provide a new model of its own.
The project is young. Its version was 0.1.7 on November 4, 2026, and the article’s source material reports 51,990 GitHub stars as of November 8. T3 Code’s site also claims more than 500,000 developers use it, a figure the source material says was not independently verified. The project is licensed under MIT, according to its materials.
The source material also notes a security-related default: new threads start in full-access mode unless the user changes the setting. That matters because coding agents may be able to interact with project files and run commands through their harnesses. Users should check the access mode and provider-specific controls before starting work.

Limits of the Early Release
The available source material does not establish how reliably T3 Code handles every supported provider, operating system or remote setup, or how its features will change after version 0.1.7. The number of providers in the installation guide may also change as the project develops.
The project’s claim that more than 500,000 developers use the app was not independently verified in the source material. It also does not provide evidence that using a shared interface improves coding accuracy or productivity. Its combined usage estimates are not subscription invoices, and the source material does not specify how closely those estimates match each user’s actual plan costs.
Users should also confirm the permissions agents receive in a given thread. The reported default is full access, but the source material does not describe all available controls or the exact behavior of every agent’s harness. Provider-specific terms, authentication requirements and plan limits continue to govern use.
What Users Should Check
Developers considering T3 Code can check the current installation guide for supported agents and setup steps, then confirm each provider’s login and plan rules. Since the project was at version 0.1.7 on November 8, users should consult its current documentation for changes to provider support and security settings.
Before starting a thread, users should review its access mode and decide which machine will run the agent. They can then test the workflow on a task whose changes are easy to inspect, review the resulting diff, and confirm that branch and pull request actions fit their team’s process. No later release or specific milestone is identified in the source material.
Key Questions
Does T3 Code include Claude Code or Codex subscriptions?
No. T3 Code provides an interface for agents such as Claude Code and Codex. Users sign in through their existing provider accounts, and providers continue to set the billing and usage limits.
Does T3 Code charge users?
The project says the app is free to use and licensed under MIT. Users may still pay their AI providers or pay separately for API usage, depending on how they configure the tools.
Can tasks be kept separate in Git?
According to the project materials, each thread can have its own Git branch and working folder. Users can review changes and use the interface to commit, push and open a pull request.
Can I use T3 Code from a phone or another computer?
The project lists desktop, web, command-line server and mobile options. Agents run on a chosen machine, while other devices can connect remotely, according to its description.
What should users know about permissions?
The source material says new threads start in full-access mode unless users change the default. Check the current settings and the agent’s permissions before running a task.
