Orca, from Stably AI, is a multi-agent orchestrator: it runs coding agents in parallel terminals, each in a git worktree, and can fan one prompt out to several of them. Its tasks come from GitHub and Linear. Cydonia runs agents over ACP, and keeps the tasks and what agents write about them in the project itself.

When to pick Orca
- You want one prompt fanned out to several agents, keeping the best result.
- Your tasks live in GitHub or Linear, and you want worktrees opened from them.
- You want to follow runs from a phone, or run worktrees over SSH.
- You want to point an agent at an element of a running web page, through its embedded Chromium.
When to pick Cydonia
- You want the tasks, and what agents find, kept in the project directory beside the code.
- You want agents to read and write those boards and articles themselves, through Cydonia's MCP tools.
- You want agents to talk to Cydonia over ACP rather than through a terminal.
