How much does Orca cost?

Orca is free. Stably publishes it under the MIT license, so the desktop app, the mobile companion apps and the full source are available at no charge. The only cost is whatever model subscription or API key the coding agent you run inside Orca already uses, since Orca does not resell inference.

Which coding agents can Orca run?

Orca works with any CLI coding agent and ships preconfigured for Claude Code, Codex, OpenCode, Cursor, Gemini, GitHub Copilot, Cline, Goose, Devin, Amp and others. Custom CLI agents can be added by hand, so a team picking Orca is not locked into one vendor's agent or one model provider.

Can I run Orca on Windows or Linux?

Orca runs on macOS for both Apple Silicon and Intel, on Windows as an .exe, and on Linux as an AppImage. Stably also publishes a Homebrew cask for macOS and an AUR package for Arch Linux. Companion apps on iOS and Android let you watch and steer a run from a phone.

Can Orca run agents on a remote machine?

Orca supports SSH-based remote worktrees, so an agent's work can execute on an external machine or a VPS while you drive it from the desktop app. Version 1.4.180 also fixed remote task agent support and native chat history restoration, both of which affect long-running remote sessions.

What is it?

Orca 1.4.180 adds stacked pull requests, so a chain of dependent GitHub PRs can be mapped and merged without leaving the app. The release also brings manual artifact sharing from the HTML and Markdown views, an artifacts management interface, live attention badges on recent chats, and a runtime toggle for agent status hooks. Stably ships Orca as an open-source desktop app under the MIT license.

How does it work?

Each task runs inside its own isolated git worktree, so parallel agents never fight over the same branch or checkout. Around every worktree the app wraps a WebGL terminal, a VS Code-based file editor, and a native Chromium window for inspecting the UI an agent just changed. GitHub and Linear browsing are built in, and any CLI coding agent can be plugged into Orca alongside the presets.

Why does it matter?

Running several coding agents at once normally means juggling terminals, branches and checkouts by hand, and reviewing their output one branch at a time. The worktree-per-task model plus the new stacked-PR support let one person land a chain of agent-written changes in order from a single window. Remote worktrees over SSH and the phone companions mean a run started on a laptop can be checked from anywhere.
