Update Scout is a native macOS app that finds and installs updates for the apps you got outside the Mac App Store. Safe, accurate, and private. Sparkle, Homebrew, and vendor sources in one place.Update Scout combines the update metadata already inside your apps with trusted vendor and Homebrew sources — then picks the safest action for each one.- Scans everywhere apps live — /Applications, ~/Applications, and your own custom folders, including apps nested in subfolders.- Five sources, one window — Sparkle appcasts, built-in vendor pages, installed Homebrew Casks, and the full Homebrew Cask catalog — each app is matched to the best available source.- Safe by design — Notarized downloads, checksum and code‑signature verification, macOS authorization only when required, and atomic replacement with rollback. Passwords are never collected by the app.- Accurate, not noisy — Smart version matching understands packaging quirks, so you don't get false “update available” alerts.- Update All in one click — Update every compatible app together — up to three concurrent downloads with live progress, cancellation, and clear per‑app results.- Backups & history — Each replaced app is retained as a restorable backup for as long as you like, and every attempt is recorded in a searchable update history.- Checks on your schedule — Check hourly, every six hours, daily, or weekly. Get a notification when updates arrive, live in the menu bar, and launch at login.- Private and native — A fast SwiftUI app with no Electron, no accounts, and no telemetry. Update Scout talks to vendor feeds — never to us.- Fully localized & accessible — Complete English, German, Spanish, and French interfaces
