TL;DR
T3 Code is a free, open-source app that brings several AI coding agents into one interface, with Git branches and review tools for individual tasks. It uses agents and subscriptions users already have; provider charges and plan limits still apply. The project was at version 0.1.7 on November 4, and some product claims, including its reported user count, have not been independently verified.
T3 Tools Inc. has developed T3 Code, a free, open-source app that lets developers use multiple AI coding agents through one interface instead of switching among separate terminals and apps. The software connects to tools and subscriptions users already have, and provides shared task threads and Git workflows; it does not replace the providers or their billing.
T3 Code’s website and documentation list support for agents including Claude Code, Codex, Cursor, Google Antigravity, OpenCode and Grok Build. Its GitHub install guide listed 10 providers on November 8, 2026, also naming Kiro, Pi, Muse Code and fx. The available integrations may vary by provider and setup.
Users authenticate with the relevant provider on the machine running the agent. T3 Code says it does not resell tokens and is free to use under the MIT open-source licence. That does not mean the underlying services are free: provider subscription limits and charges remain in place. The product also permits separate API-key or OpenRouter configurations, according to its FAQ.
A work thread can use its own Git branch and working directory, allowing tasks to run separately. T3 Code’s interface can show changes for review and support committing, pushing and opening a pull request. The company also describes switching agents within a thread. Its documentation says a handoff may carry over a shortened conversation, while the original agent’s internal reasoning, tool state and attachments do not transfer.
Infographic 01 · One surface, your own plans
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
For developers paying for or using more than one coding agent, the practical promise is less app switching and a common place to inspect work. A shared interface may also make it easier to assign one agent a task and ask another to review it, though the quality of that process depends on the agents and the developer’s checks.
Separate worktrees and branches address a concrete coordination problem: concurrent coding tasks can otherwise affect the same files. Keeping tasks isolated can make changes easier to compare and review before they are committed. T3 Code does not, however, establish that agents will produce compatible or correct code; developers still need to examine diffs and run appropriate tests.
The product’s bring-your-own-subscription model also distinguishes it from a service selling access to a bundled model. Users retain their existing provider relationships and limits, while T3 Code acts as an interface layer. Its usage page presents API-equivalent estimates, according to the documentation, rather than a statement of what users owe under their subscriptions.

A Layer Above Existing Coding Tools
AI coding products commonly combine a model with a harness: software that lets the model inspect files, run commands and make changes. T3 Code’s FAQ says the app is neither a model nor a harness; it uses harnesses users have installed and places a shared interface above them. Its website describes this as a control plane for coding agents.
The project describes access through desktop apps for macOS, Windows and Linux, a web app, a command-line server and mobile apps for iOS and Android. According to its site, the agents run on a machine selected by the user, while other devices can connect remotely. That setup makes the app relevant to developers who want to monitor work away from the computer running the agents, but the source material does not detail security configurations for every deployment.
T3 Code was at version 0.1.7 on November 4, 2026, indicating an early-stage release. The source reported 51,990 GitHub stars on November 8 and said the company’s site claimed more than 500,000 developers use the product. The star count is a dated observation; the claimed user figure was not independently verified in the source report.

Limits, Security and Adoption Claims
The available source material does not establish how well every listed agent works across different operating systems, plans or project setups. It also does not provide independent testing of the quality of agent handoffs, the reliability of pull-request actions or the accuracy of the usage estimates. Those details matter because integrations can behave differently even when they appear in one interface.
Security and access controls are also not fully described in the material provided. New threads reportedly start in full-access mode unless users change the default. Developers should check permissions and provider terms before allowing an agent to run commands or edit files; the source does not specify all safeguards or defaults for each supported harness.
The site’s claim that more than 500,000 developers use T3 Code could not be independently checked in the source report. The project’s early version number also means its feature set and provider support may change. No information was supplied about a release schedule, commercial plans or how long each integration will remain supported.
What Developers Should Check
The immediate next step for interested developers is to consult T3 Code’s current installation guide and verify that their preferred agent, operating system and authentication method are supported. They should also review the permissions for new threads, confirm how their provider handles usage and check whether work runs locally or on a remote machine in their chosen setup.
As the project develops beyond version 0.1.7, users can watch for updates to provider support, security documentation and thread handoff behavior. The source material gives no date for a next release. For now, T3 Code presents itself as an optional coordination layer: useful to test for people juggling several agents, but not a replacement for provider subscriptions or human review of generated code.
Key Questions
Does T3 Code include AI models or tokens?
No. T3 Code says it connects to coding agents and harnesses users already have. Provider subscriptions, usage limits and charges remain separate.
Which coding agents does T3 Code support?
The project lists Claude Code, Codex, Cursor, Google Antigravity, OpenCode and Grok Build, among others. Its GitHub guide listed 10 providers on November 8, 2026; users should check the current guide for changes.
Can different agents work on separate tasks at once?
T3 Code says a thread can have its own Git branch and working directory, which is intended to keep parallel tasks separate. Developers still need to review changes and test the resulting code.
What happens when a user switches agents mid-thread?
According to the documentation, T3 Code can hand conversation context to another agent, sometimes selecting only key messages and activity for longer threads. The previous agent’s internal reasoning, tool state and attachments do not carry over.
Is T3 Code free, and is it ready for every workflow?
The app is described as free and open source under the MIT licence. Its source material identifies it as version 0.1.7 and does not establish that every integration or workflow is reliable for every user, so developers should check current documentation and permissions.
