T3 Code is a free, open-source app that brings several AI coding agents into one workspace and lets developers manage task branches and review changes in the same interface. It uses users’ existing provider accounts, so their subscriptions and plan limits still apply. The project was at version 0.1.7 on November 4, 2026, and some product claims, including its reported user count, have not been independently verified.
T3 Code, an open-source app from T3 Tools Inc., brings multiple AI coding agents—including Claude Code, Codex, Cursor and Google’s Antigravity—into one interface for managing coding tasks and reviewing changes. The app is free and uses the accounts developers already have with each provider, whose subscription fees and usage limits still apply.
T3 Code presents itself as a shared interface for coding agents rather than a new model or agent harness. Its FAQ says the app uses harnesses installed by the user and provides a common surface for interacting with them. The project’s homepage describes it as “the open-source control plane for coding agents.” Its code is available under the MIT licence.
The project’s homepage lists Claude Code, Codex, Antigravity, OpenCode, Cursor and Grok among supported agents. A GitHub install guide listed 10 providers on November 8, also naming Kiro, Pi, Muse Code and fx. The specific sign-in steps vary by provider, and developers need to configure the tools on the machine where the agents will run.
Work can be organized into threads, with a separate Git branch and working folder for a task, according to the source material. Users can inspect a diff and then commit, push and open a pull request through the interface. T3 Code also offers desktop, web, command-line server and mobile access; the agents run on a selected machine, while other devices can connect remotely. The project was at version 0.1.7 on November 4, 2026.
One workspace for coding agents T3 Code connects your tools
T3 Code brings multiple AI coding agents into one interface for tasks and code review. It organizes existing tools; provider accounts, fees and limits still apply.
A shared workspace
The interface coordinates agents developers already use; it is not a new model or harness.
Use existing accounts
Connect tools such as Claude Code, Codex, Cursor and Antigravity through their own sign-in steps.
Keep tasks separate
Threads can use separate Git branches and working folders to help manage parallel work.
Inspect changes
Review a diff, then commit, push and open a pull request through the interface.
How work moves
Set up the provider tool on the machine where the agent will run.
Work in its own branch and folder, then inspect the changes.
Commit and push approved work or open a pull request.
What the workspace changes
Its value depends on how many tools and devices a developer already uses.
- Manage several agents in one interface
- Review parallel tasks with separate branches
- Connect remotely from desktop, web, command line or mobile
- Provider subscriptions and plan limits
- Different sign-in steps and provider terms
- Agent runs on a selected machine
Early release, open questions
The supplied material does not include independent reliability tests or comparisons.
One Workspace for Agent Reviews
Developers who use several coding agents can face separate apps, terminals and histories. T3 Code’s shared thread and diff view is intended to make it easier to manage parallel tasks and compare work without switching between as many interfaces. Separate branches can also help keep agent changes organized for review.
The product’s practical value depends on a developer’s workflow. Someone who uses several agents or needs to check work remotely may find a common interface useful. A developer who is satisfied with one tool in one terminal may have less reason to add another layer. The source describes features and intended benefits, but does not provide independent performance comparisons or evidence that the app improves coding outcomes.
Using the app does not consolidate provider billing or remove provider restrictions. Users continue to authenticate with their existing accounts, and plan limits remain in force. T3 Code’s usage page combines token data, but its documentation says cost figures are API-equivalent estimates, not a statement of the user’s actual subscription bill.

How T3 Code Fits Existing Tools
AI coding products often combine a model with a harness: software that lets the model inspect files and run commands. T3 Code’s FAQ says it is neither a model nor a harness. Instead, it puts an interface over harnesses developers already use. That distinction means its stated purpose is to coordinate access, task threads and review rather than replace a provider’s coding system.
The project says users can authenticate through each tool’s own login, or add a separate provider instance using API keys or OpenRouter. Its materials say it does not resell tokens and does not impose its own quota caps. Those statements describe T3 Code’s billing arrangement; they do not remove the terms, costs or limits set by the underlying providers.
As of November 8, the project’s GitHub repository showed 51,990 stars, while its homepage rounded the figure to “51k+.” The site also reported more than 500,000 developers using the product, a figure the source material says could not be independently checked. Star counts and company-reported user totals indicate attention, but do not by themselves establish adoption or product reliability.

Early Release, Open Questions
The available source material does not establish how reliably each listed provider works across operating systems, how remote connections are secured, or how the app handles failures and conflicting edits during parallel tasks. It also does not include independent testing of the workflow or comparative measurements against using the providers directly.
T3 Code was at version 0.1.7 on November 4, making it an early release. The reported total of more than 500,000 developers comes from the project’s own site and was not independently verified in the supplied material. Provider terms, authentication behavior and plan limits may also differ, so users should check the rules for each service they connect.
Provider Support and Product Maturity
Developers considering T3 Code can consult its current installation guide to confirm provider support and sign-in requirements, then try it with a task they can review before relying on it for broader work. The project’s next practical milestones are likely to be changes in provider support, app stability and documentation as releases continue. The source material gives no specific release schedule or confirmed roadmap, so the timing of further updates is unclear.
Key Questions
What is T3 Code?
T3 Code is a free, open-source interface for using and managing multiple AI coding agents. It is not presented as a new model or a replacement for the agents’ own harnesses.
Does T3 Code include AI subscriptions?
No. Users sign in through their existing provider accounts, and provider fees and plan limits still apply. The project says it does not resell tokens.
Which coding agents does it support?
The homepage names Claude Code, Codex, Antigravity, OpenCode, Cursor and Grok. The GitHub install guide listed 10 providers on November 8, 2026, including Kiro, Pi, Muse Code and fx; support can change over time.
Can developers review and submit code changes in the app?
According to the source material, each task can use its own Git branch and working folder. Users can review a diff, then commit, push and open a pull request through the interface.
Is T3 Code ready for every development workflow?
The project was at version 0.1.7 on November 4, 2026. The supplied material does not include independent reliability testing, so developers should check current provider support and evaluate the app against their own workflow.
