CodonTerminal

The cockpit for the AI coding tools you already pay for. Run Claude Code, Codex, Gemini CLI, Copilot CLI, Cursor Agent and more side by side - up to 16 in one window, each on its own model. Queue the work and each task goes to whichever signed-in subscription has room, in its own git worktree; when a plan hits its usage limit, that task moves to the next one. You review the diff and merge. It replaces the tmux / WSL / Windows Terminal juggling act with one clean app.

Before you start

CodonTerminal doesn't bundle an AI of its own - it drives the coding tools installed on your machine, each signed in the way its vendor intends. Any one of these is enough to get started, and each is free to install and runs on the plan you already pay for. Install more than one and the queue spreads the work across them.

  • Claude Code

    The one most people start with. It works on your Claude subscription or on API billing, whichever you prefer, and CodonTerminal picks up the install on its own.

  • OpenAI Codex

    Prefer OpenAI's models, or want a second plan for the queue to use? Install Codex - the desktop app or the CLI, either one - and CodonTerminal finds it on its own. Its models appear in the model menu and run on the ChatGPT plan you already pay for. There's nothing to configure.

Already paying for one of these instead? They work the same way - each is detected on its own and shows its sign-in status in Settings. Gemini CLI, Copilot CLI and Cursor Agent can take queued tasks; Grok Build runs in agent panes only, because it has no non-interactive mode yet. Amp, OpenCode and Aider run in agent panes too.

What it does

  • Run up to 16 agents side by side - Claude Code, Codex, Gemini CLI, Copilot CLI, Cursor Agent, Grok Build and more, each pane on its own model, or a plain shell.
  • Use every plan you pay for: queued tasks start on their own on whichever signed-in subscription has room, in the priority order you set. Pause the queue any time.
  • Limit-aware routing: when a plan hits its usage limit, that account rests until its reset time and the task moves to the next one. A limit doesn't count as a failure.
  • Every task runs in its own git worktree on its own branch, so parallel agents can't clobber each other or your working tree.
  • Review each result as a live log, a summary and a full diff, then Merge, Send back with a note (the next attempt continues on the same branch), or Discard.
  • Add your own API models as overflow - OpenRouter, any OpenAI- or Anthropic-compatible endpoint, or a LiteLLM gateway - used for queued tasks only when you switch on overflow, which stops for the day at a spending cap you set.
  • Codon MCP is built in: Claude Code, Codex, Cursor and other MCP clients share the same task queue, and can claim work and report it done.
  • Watch the queue and live runs from your browser with the Command Center, served by the app on your own machine.
  • Pick a UI element in a live preview with Design Mode and turn it into a task or an agent prompt, with the screenshot attached.
  • See what every agent was asked in Activity, and talk to your agents on Windows: hold Alt to speak to the focused one, or dictate into Compose. Speech is transcribed on your machine.

Runs on

WindowsLinux (.deb)Linux (AppImage)

Disk space

The Windows installer is about 145 MB and the installed application files total about 480 MB. On Linux the .deb is about 85 MB (the AppImage 120 MB) and installs about 290 MB. Voice input (Windows only) downloads a 2.3 GB speech model on first use and runs on your machine.

Windows is current at 2.1.0 and Linux at 2.1.0: the same app on both. On Linux, pick the .deb for Ubuntu, Debian, Mint or Pop!_OS; the AppImage covers most other distributions (on Ubuntu 23.10 and later it needs --no-sandbox, so use the .deb there). No macOS yet: it isn't signed with an Apple Developer ID, and we won't sell a download macOS refuses to open. One purchase covers every download.
