Barnacles is a Mac app. Open this page on your Mac to download it.

macOS asks you to confirm it the first time. Here's how

Or install from Terminal:

$ curl -fsSL https://raw.githubusercontent.com/eloigil/barnacles/main/install.sh | bash

The Barnacles window, listing four Orca instances: Client site, Code review, Experiments and Work

One Orca wasn't enough.

Orca lets only one instance run per profile. Barnacles gives each instance its own profile, so they never block each other, and your normal Orca keeps running as usual.

Separate instances

Each barnacle has its own projects, workspaces and terminal sessions.

Your settings, copied

New barnacles start with your Orca's theme, fonts, agents and preferences.

A new window, fast

Right-click Barnacles in the Dock and choose New Orca Window, or press ⇧⌘N.

In Spotlight and the Dock

Every barnacle gets a launcher with a colored badge. Search “Orca Work” to open it.

Opening it the first time

Barnacles isn't notarized by Apple yet, so macOS asks you to confirm it the first time. You only do this once. (The Terminal install above skips this step.)

  1. Open Barnacles.dmg and drag Barnacles into Applications.
  2. Open Barnacles. macOS says it can't verify the developer. Click Done.
  3. Open System Settings → Privacy & Security, scroll down and click Open Anyway next to Barnacles, then confirm.

You need Orca installed. Barnacles never touches your code or repositories; deleting a barnacle moves only its Orca data to the Trash.
