Best licensing platforms for macOS and Swift apps

First, the distinction that trips people up: a licensing platform is not a payment platform. Paddle, Lemon Squeezy, and Polar take the money. A licensing platform decides who gets to run your app, on which machines, for how long. Most paid apps need both. This list is the licensing half, for macOS and Swift apps.

Here’s the field, and what each one is actually best at.

The best macOS licensing platforms

1. Keylight — best Apple-native licensing

Built for Apple, not adapted to it. Native Swift SDK with a licensing state machine, offline Ed25519 leases your app verifies locally, and Stripe wired in so a payment mints the license with no webhook code. Feature flags ride in the lease. If you’re shipping a Mac or Swift app and want licensing that drops in instead of a project, this is the one. Apple-native first, and not stopping there. See the vs Keyforge and vs Keygen breakdowns.

2. Keygen — best flexible, language-agnostic API

The name most people know. Keygen is deep, mature, language-agnostic, and self-hostable if you want to own the stack. You bring your own payments and wire the flow yourself — more work, more control. Best when you want primitives, not an opinionated path. Full comparison.

3. Keyforge — best simple indie REST option

Closest in spirit to Keylight: indie-focused, no-backend, offline JWTs, integrates Stripe, Polar, and Lemon Squeezy. It’s a REST API you call from any language, so it’s a good fit when you’re not Apple-first. Full comparison.

4. Cryptlex — best for floating and hardware-bound licensing

A capable cross-platform engine. If you need floating or concurrent seats, hardware-locked licenses, or on-prem deployment, Cryptlex does those out of the box via its LexActivator SDK. Full comparison.

5. LicenseSpring — best for cross-platform and enterprise

Broad and enterprise-ready: multi-language SDKs, node-locked, floating, and consumption models, a free tier to start. The right call for cross-platform products or a licensing program with procurement attached. Full comparison.

Licensing platforms vs payment platforms

Lemon Squeezy and Paddle will hand you a license key, and for a simple product that can be enough. But they’re payment-first — the licensing is a feature, not the product. They don’t do device limits, offline leases, or feature flags the way a dedicated layer does. Most apps end up pairing a payment processor with a real licensing platform. More on what a dedicated licensing API actually does.

How to choose

Quick version:

• Apple app, want it done → Keylight.
• Many languages or self-hosting → Keygen.
• Not Apple-first, want simple REST → Keyforge.
• Floating seats or hardware-locked → Cryptlex.
• Cross-platform or enterprise program → LicenseSpring.

If you’re an indie shipping on the Mac, the honest answer is Keylight — it’s the one built for exactly that.

Where Keylight fits

Plans start at $19/month, with a free tier. Wire Stripe, drop in the Swift SDK, ship.
