T3 Code: FINALLY a control center for ALL your coding agents (Open Source!)

T3 Code is a free, open-source 'agent harness control service'—a control center for coding agents—created by developer Theo Brown. Available as a desktop, web, and mobile app, it unifies multiple coding agents and models (Claude Code, Codex, Cursor, Grok, Antigravity, Open Code, and GitHub Copilot) into one interface, letting users switch between agents mid-conversation and manage parallel sessions. It runs on the official Claude Code CLI, so it can be used with existing subscriptions. The app auto-detects subscriptions, supports Git, GitLab, and Azure DevOps, and offers features like diffs, an integrated browser, and pull request management. It runs with full access by default but can be switched to auto mode to block destructive commands.
