TL;DR
T3 Code brings supported AI coding agents into one interface and can give each task its own Git branch and working folder. The free, MIT-licensed project uses providers’ existing sign-ins and subscriptions; it does not sell tokens or replace provider limits.
T3 Code, an open-source app for coordinating AI coding agents, brings tools such as Claude Code, Codex and Cursor into one interface, where developers can manage separate tasks, review code changes and use Git actions. A November 8 report says the app is free and uses developers’ existing provider accounts rather than selling access to models, making it relevant to programmers who work across several coding tools.
T3 Code does not provide its own AI model or coding harness, according to its FAQ. Instead, it puts an interface over agents and harnesses users have installed and signed into. The project describes itself as an “open-source control plane for coding agents.” The report says it is available as desktop software for macOS, Windows and Linux, as a web app and command-line server, and through mobile apps for iOS and Android. Agents run on a machine selected by the user; other devices can connect to it remotely.
The report lists Claude Code, Codex, Antigravity, OpenCode, Cursor and Grok among the agents named on the homepage. The project’s GitHub installation guide listed 10 providers on November 8, adding Kiro, Pi, Muse Code and fx. The tools can appear in a shared thread view with a diff panel and Git actions. Users can also switch providers within a thread, though the handoff does not preserve every part of the previous agent’s internal state.
For parallel work, a thread started with the “New worktree” option can receive its own Git branch and working folder. The report says users can review changes and then commit, push and open a pull request from the interface. T3 Code also has a Usage page that combines token-use information; its documentation describes cost figures as API-equivalent estimates, not a record of what a user’s subscription bill will be.

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 Parallel Agents
Developers who use several coding agents can otherwise face separate applications, sign-ins and work histories. T3 Code’s main practical proposition is to bring those workflows together, so users can track which thread is handling a task and compare or review changes without moving between as many interfaces. That organization may be useful when work is split among agents or developers need to connect to a running session from another device.
The Git worktree feature addresses a concrete risk in parallel coding: separate tasks can make changes in separate working folders and branches rather than competing in one checkout. The shared diff and Git actions keep review and pull-request steps near the agent conversation. These features do not establish that agent output is correct; developers still need to inspect changes and decide whether they are suitable to merge.
The pricing model also matters to users evaluating another layer in their development setup. T3 Code itself is described as free, but provider charges and subscription limits remain. The report says the project does not resell tokens, so it does not remove the cost of using the underlying services.

A Layer Over Existing Coding Tools
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 the project is neither a model nor a harness. It is intended to sit above existing tools, using their own sign-in methods. Users therefore need to install and authenticate with the provider or agent they want to run.
The project is distributed under the MIT open-source licence. The source report counted 51,990 GitHub stars on November 8, 2026, while the homepage rounded that figure to “51k+.” The website also claimed more than 500,000 developers use T3 Code; the report said it could not independently verify that user figure. The project was at version 0.1.7 on November 4, a sign that the software was still at an early release stage at the time covered.
Provider access and billing remain separate from T3 Code. Its site says users sign in through each tool’s own account, and its documentation describes optional API-key or OpenRouter configurations. The report also notes that the displayed cost estimates are not equivalent to subscription invoices, which may have different plan terms and usage limits.

Limits of the Early Release
The available report does not independently verify the project website’s claim that more than 500,000 developers use T3 Code. It also does not establish how reliably every listed agent works across operating systems, accounts or different task types. The version cited, 0.1.7, was released November 4, 2026, so features and compatibility may change.
Switching agents within a thread does not carry over all prior information. According to the project documentation summarized in the report, a handoff can include selected conversation content and relevant activity, while the earlier agent’s internal reasoning, tool state and attachments stay behind. The report does not specify how often that loss of context affects results.
Users should also note that new threads reportedly start in full-access mode unless they change the default. The source does not detail the precise permissions involved or assess the security implications for every setup. Provider terms, account limits and billing remain governed by each service, not by T3 Code.
Check Compatibility Before Adoption
Developers considering the app can check the current installation guide for supported providers, sign-in steps and operating-system requirements, then test it on a small task before moving parallel or production work into it. They should review the access setting for new threads and inspect agent-generated diffs before committing or opening pull requests.
The source material does not announce a future release date or a specific upcoming feature. The next developments to watch are changes to provider support, the early-version software and its documentation. Users will also need to confirm that their provider subscriptions and terms permit their intended use; T3 Code does not change those arrangements.
Key Questions
What is T3 Code?
T3 Code is an open-source interface for running and organizing supported coding agents. It does not supply its own model or coding harness, according to its FAQ.
Does T3 Code include AI model access?
No. The report says users sign in with the providers they already use. Provider billing and plan limits continue to apply.
Can T3 Code keep coding tasks separate?
Yes. The report says a thread started with the “New worktree” option can use its own Git branch and working folder, helping separate parallel tasks.
Does switching agents preserve the whole conversation?
Not necessarily. Project documentation says a handoff carries selected conversation content and relevant activity, but not the prior agent’s internal reasoning, tool state or attachments.
Is T3 Code mature software?
The source report cited version 0.1.7 from November 4, 2026. That early version number means users should check current documentation and test compatibility before relying on it for important work.
