Orca
Orca is a desktop and mobile agent development environment for running several coding agents, such as Claude Code, Codex or OpenCode, side by side, each in its own isolated git worktree.
A mobile companion app lets a user monitor agents and send follow-ups from a phone, and one prompt can be fanned out across several agents in parallel worktrees so the results can be compared and merged. Built-in terminals render with WebGL and keep scrollback across restarts, a design mode captures a clicked UI element's HTML, CSS and screenshot into a prompt, and GitHub and Linear issues and PRs can be browsed and turned into a worktree without leaving the app.
Agents can also run over SSH on a remote machine with full editing and terminal access, diff comments can be sent back to an agent for revision, and an included CLI lets scripts drive worktree creation and other actions. It tracks per-provider usage and rate limits and supports account switching without re-authenticating.
Available for macOS, Windows, Linux, iOS and Android. TypeScript, MIT.
