Synara vs T3 Code

T3 Code is a free, MIT-licensed control plane for coding agents, with a desktop app, a hosted web app, a CLI and iOS and Android apps. Synara is also free and MIT-licensed, and focuses on the desktop workspace around the agents, with a Kanban board and Inbox, split views, Computer Use, Hubs, Studio and Debug mode.

Key differences from T3 Code

  • Workspace: Synara has a Kanban board and Inbox for tasks, split views that keep two chats side by side, Computer Use for Mac apps (beta), Hubs and Library for work across repositories, Studio for long-running work, and Debug mode. T3 Code's documentation doesn't describe these.
  • Pull requests: both review, comment on and merge pull requests, including stacked PRs. Synara can also send a linked chat to fix failing CI checks.
  • Agents: T3 Code builds in Codex, Claude, Cursor, Grok Build, OpenCode, Pi, Antigravity, fx and Muse Code, and adds Devin, Droid, GitHub Copilot and other agents through the ACP Registry. Synara runs ten runtimes, including Oh My Pi, which T3 Code doesn't list.
  • Mobile and web: T3 Code already ships a hosted web app, a CLI and iOS and Android apps. Synara is a desktop app with a headless server package; Synara Remote and native iPhone and iPad apps are coming soon.
  • Shared ground: both switch providers mid-thread with portable context, keep agents working toward a goal, run scheduled tasks and show a live iOS Simulator next to the agent. T3 Code also supports the Android Emulator.
