Orca (GitHub Repo)
Orca is an open-source orchestrator that lets developers run multiple AI coding agents simultaneously in isolated Git worktrees for side-by-side comparison.
Deep dive
- Supports parallel execution of 30+ AI agents like Claude Code, Codex, and OpenCode.
- Uses isolated Git worktrees for each agent to allow side-by-side result comparison.
- Includes a mobile companion app for monitoring and steering agents remotely.
- Features a 'Design Mode' that captures UI elements (HTML/CSS) to provide visual context to agents.
- Offers integrated code review and terminal splitting capabilities.
Decoder
- Git Worktree: A feature of Git that allows you to have multiple branches checked out in different directories simultaneously, which Orca uses to isolate agent environments.

Features
Mobile Companion
Monitor and steer your agents from your phone — get notified when an agent finishes and send follow-ups from anywhere.
iOS App Store · TestFlight · Android APK · Docs →
Parallel Worktrees
Fan one prompt across five agents, each in its own isolated git worktree — compare the results and merge the winner.
Terminal Splits
Ghostty-class terminals with WebGL rendering, infinite splits, and scrollback that survives restarts.
Design Mode
Click any UI element in a real Chromium window to send its HTML, CSS, and a cropped screenshot straight into your agent's prompt.
GitHub & Linear, Native
Browse PRs, issues, and project boards in-app — open a worktree from any task and review without a context switch.
SSH Worktrees
Run agents on a beefy remote box with full file editing, git, and terminals — auto-reconnect and port forwarding included.
Annotate AI Diffs
Drop comments on any diff line and ship them back to the agent — review, edit, and commit without leaving Orca.
Drag Files to Agents
VS Code's editor with autosave everywhere — drag files or images straight into an agent prompt.
Orca CLI
Agents drive Orca too — script every workflow with orca worktree create, snapshot, click, and fill.
Also in the box:
- Quick open — Search across worktrees, files, agents, commands, and repo context without leaving your flow.
- Account switcher & usage tracking — See Claude and Codex usage and rate-limit resets, and hot-swap accounts without re-logging in.
- Rich repo previews — Preview Markdown, images, PDFs, and repo docs in the workspace.
- Computer Use — Let agents operate desktop apps and visible UI when a workflow needs real interaction.
- Notifications and unread state — Know when an agent finishes or needs attention, then mark threads unread to come back later.
- And many, many more — we ship daily, so this list is perpetually behind. The changelog is the real feature list.
Supported Agents
Works with any CLI agent — if it runs in a terminal, it runs in Orca.
