T3 Code

T3 Code is an open-source control plane from Theo / Ping Labs (GitHub: pingdotgg/t3code) for the coding agents you already pay for, rather than another token reseller. The site at https://t3.codes calls it “The open-source control plane for coding agents.” The homepage says it orchestrates Claude Code, Codex, Antigravity, OpenCode, Cursor, and Grok from one surface; the radar excerpt also listed Grok Build and fx. The product is explicitly bring-your-own-subscription: T3 Code does not resell tokens. You plug in the credentials you already have, and the site says you can switch models mid-thread.

It ships desktop builds (macOS Apple Silicon and Intel, Windows, Linux .deb and AppImage), a mobile option, and a terminal installer. On macOS or Linux: curl -fsSL https://t3.codes/install.sh | sh. On Windows: irm https://t3.codes/install.ps1 | iex. You can also try npx t3@latest without installing. After install, run t3. The project is meant to be forked: gh repo fork pingdotgg/t3code --clone.

Highlights:

• Site https://t3.codes , downloads at https://t3.codes/download , source at https://github.com/pingdotgg/t3code ;
• Free and open source; official copy says no keys resold and no extra quota caps from T3 itself;
• Each agent thread writes to its own branch; one button commits, pushes, and opens a GitHub PR with a generated title, body, and changelog, with inline diff review plus draft, stacked, and amended PRs;
• Radar recorded about 53.9k GitHub stars on the weekly trending list in this window; the marketing page says it is “Tolerated by over 500,000 devs.”

Why it matters

Many developers already pay for Claude Code, Codex, Cursor, or another harness and just want one surface that is not locked to a single vendor. T3 Code is that layer: open source, forkable, and billed through the subscriptions you already have. The site also highlights remote connections (including reaching a remote VM without Tailscale) and continuing work from a browser or phone, plus a one-button path from an agent thread to a GitHub PR so you spend less time switching branches and writing commit copy in the terminal.

It showed up on GitHub’s weekly trending list in this scan window, which is a useful attention signal. If you want to drive several coding agents without buying tokens from yet another middle layer, that is a shorter path than learning a proprietary orchestrator.

Limits

T3 Code orchestrates agents and plans you already have; it does not sell model inference. Whether a given harness works depends on current integrations and on your own account. Treat the homepage list as the supported set, and double-check names that appeared only in the radar excerpt (such as Grok Build and fx) against the repo and download page. Desktop apps, install scripts, and self-hosted builds run on your machines, so security and update cadence follow upstream releases. Star counts and the “500,000 devs” line are a scan-time observation or marketing copy, not a benchmark score.

1. Open https://t3.codes or https://t3.codes/download and grab a desktop build, or install from a terminal with curl -fsSL https://t3.codes/install.sh | sh (Windows: irm https://t3.codes/install.ps1 | iex). To try it once, run npx t3@latest;
2. After install, run t3 and connect the Claude Code, Codex, Cursor, Grok, OpenCode, or Antigravity credentials you already have—T3 Code does not resell tokens;
3. Let each agent thread work on its own branch, then use the built-in button to review the diff and open a GitHub PR;
4. To restyle the UI or add your own agent, fork https://github.com/pingdotgg/t3code and follow the repo’s build instructions. Read any curl | sh script before running it, and confirm it comes from t3.codes.
