oh-my-just-open

A small macOS default-app manager for files and URLs.

oh-my-just-open is a native macOS utility for choosing the default app for URL schemes and file types. It is built in SwiftUI, distributed through Homebrew, and designed for developers and Mac power users who want direct control over what opens what.

Install with Homebrew

Homebrew is the supported install and update path.

brew tap blas0/omjo
brew install --cask oh-my-just-open

URL scheme routing

Choose what handles links such as http, mailto, xcode, and other schemes without digging through app-specific settings.

File type control

Review file extensions and content types, then assign the app that should open each one by default.

Homebrew updates

Installs and updates are handled through a self-hosted Homebrew cask, so upgrades fit into the same workflow as the rest of your Mac tooling.
