Homebrew (macOS)

Orca is also published as a Homebrew cask, auto-bumped on every stable release:

brew install --cask orca

brew upgrade --cask orca picks up new stable builds. The cask tracks the stable channel — for RC builds, use the GitHub Releases links above or the in-app Check for Updates flow described under Updates.

First launch

On first launch Orca will:

• Ask for access to your home directory so it can add repos.
• Offer to import ~/.claude, ~/.codex, and Ghostty terminal settings if present.
• Drop you on an empty landing screen where you add your first repo.

Updates

Orca auto-updates by default, tracking the stable channel. Stable releases are vetted; RC (release candidate) builds ship new features first, often daily.

There is no in-app opt-in for the RC channel. To pull an RC build, either:

• Hold Shift while clicking Check for Updates (Settings → General → Updates, or the app / Help menu). That single check will include prereleases.
• Or download any build directly from the GitHub Releases page.

Platform notes

macOS

Signed and notarized. On first launch, macOS may still ask you to confirm — that's normal for Electron-based apps.

Windows

The default shell can be set to PowerShell or CMD under Settings → Terminal. Most users want PowerShell.

Linux

AppImage and .deb builds are available. See the Releases page for details.
