Development

pnpm install
pnpm dev

pnpm lint, pnpm typecheck, pnpm test, pnpm e2e mirror CI.

Installation

Add the tap and install with Homebrew:

brew tap vtmocanu/tap
brew install --cask vtmocanu/tap/zeo
xattr -dr com.apple.quarantine /Applications/zeo.app

Upgrade: brew upgrade --cask zeo.

Uninstall: brew uninstall --cask zeo; to also remove app data: brew uninstall --cask --zap zeo.

zeo ships as an ad-hoc signed build — no Apple Developer ID signature and no notarization — so macOS Gatekeeper quarantines it and blocks the first launch ("zeo can't be opened because Apple cannot check it for malicious software"). The xattr command above clears the quarantine attribute; run it again after each brew upgrade. Alternatively, right-click zeo.app in Finder and choose Open once.

Apple Silicon (arm64) only.
