Auto-updates and licensing for macOS apps.

Shimmer is a modern alternative to Sparkle that combines automatic updates with built-in license management. One SDK, one dashboard, no more duct-taping multiple services together.

• Auto-updates — Seamless background updates with support for delta patches
• License management — Generate, validate, and revoke licenses from a single dashboard
• Gated releases — Tie updates to license status (e.g., major versions require active license)
• Release channels — Ship to beta testers and stable users separately
• Hosted distribution — CDN-backed hosting for your binaries and appcasts
• Offline validation — Cryptographically signed licenses that work without network calls

dependencies: [
    .package(url: "https://github.com/tuist/shimmer.git", from: "0.1.0")

import Shimmer

// Initialize with your app credentials
let shimmer = Shimmer(appId: "your-app-id", publicKey: "your-public-key")

// Check for updates
shimmer.checkForUpdates()

// Validate a license
let result = await shimmer.validate(licenseKey: "XXXX-XXXX-XXXX-XXXX")

Coming soon.
