User buys your app
Customer purchases through your existing flow.
LicenseSeat issues a key
We generate a unique license key and send it to your customer.
Your app verifies it
Validate the key with our SDK in just a few lines of code.
import LicenseSeat from '@licenseseat/js';
// 1. Initialize the SDK
const sdk = new LicenseSeat({ apiKey: 'your-api-key' });
// 2. Activate a license
await sdk.activate('XXXX-XXXX-XXXX-XXXX');
// 3. Check entitlements
if (sdk.hasEntitlement('pro')) {
// Enable pro features
}Works with Unity, Unreal Engine, Godot, macOS, Windows, Electron, and more. Docs
Stop losing sales to piracy
Pirates are stealing up to 20% of your launch revenue. Most indie games, small tools and apps get cracked in the first week. LicenseSeat adds friction and control—without hurting honest users.
- Prevent key sharing & license abuse
- Enforce per-device or per-seat limits
- Revoke stolen or abused keys instantly
- Offline activation supported
"But I can just roll my own licensing server!"
Sure, go ahead! But soon you'll realize building it right is harder than it looks. You'll spend weeks on secure cryptography, edge cases, and maintenance—time not spent improving your product for users.
Integrate with your existing payment processor
We connect and integrate with your own payment system (Gumroad, Stripe, PayPal, Paddle, custom, etc) to automate license issuance upon purchase, automatically delivered to your users via email. No markup, 0% revenue share—we take no cut of what you make.
