SuperDevSpace vs T3 Code
T3 Code is an open-source (MIT) "agent harness control surface" with desktop, web and mobile apps that works with your subscriptions on Claude Code, Codex, Cursor and others. SuperDevSpace also runs on the CLI you already pay for, and organises the agents into a team: a manager that plans and workers in their own git worktrees.
| Aspect | SuperDevSpace | T3 Code |
|---|---|---|
| What it is | A desktop app: a manager agent plans, worker agents build in parallel | An "agent harness control surface" |
| Apps | Desktop for macOS, Windows, and Linux; a phone companion is in invitation-only beta | Electron desktop app, a local web app, iOS and Android apps |
| Agents | Claude Code (full), OpenAI Codex, Gemini CLI, Aider, Qwen Code, Cursor CLI, and OpenCode (experimental) | Claude Code, Codex, Cursor, Grok Build, OpenCode, Google Antigravity |
| Planning layer | A manager agent opens a sprint, writes briefs and hires workers | Not described in its README |
| Model access | Your own CLI subscription; we resell no tokens | Your own subscriptions on the supported agents |
| Licence and price | Commercial subscription, 14-day free trial | Open source, MIT; its README says it sells nothing |
| Maturity | Version 0.9.30, signed and notarised on macOS | Its README: "very very early in this project. Expect bugs." |
