LicenseGate

LicenseGate is a SaaS platform for managing license keys, built for indie developers and small software teams. You can create, validate and manage license keys without having to build your own infrastructure.

Whether you sell a browser plugin, a desktop app or a SaaS product: LicenseGate provides you with a ready made API and SDKs to integrate licenses into your software.

The platform handles the entire logic: key generation, activation limits, expiration dates and usage statistics.

You create an account on LicenseGate and set up a new product. For each product you can generate license keys, either individually or in batches.

Each license key has configurable properties: activation limit (how many devices), expiration date, feature flags and notes. Through the dashboard you can see all licenses, their status and activation history.

In your software you integrate validation via the REST API or the JavaScript SDK. With just a few lines of code you check on each launch whether the entered license key is valid and which features are unlocked.

LicenseGate is suitable for various software products.

Browser extension developers use LicenseGate to unlock premium features. The user buys a license, enters the key in the extension and gets access to advanced features.

Desktop app developers integrate LicenseGate via the REST API. On each launch, the app checks the license key and enables or disables features accordingly.

SaaS developers use LicenseGate for self hosted software or on premise solutions where API based license checking is needed.

WordPress plugin and theme developers can use LicenseGate to deliver updates only to paying customers.

LicenseGate is built with Next.js 15 and TypeScript. The backend uses Supabase for database and authentication. Payments are processed through Stripe. Emails for license notifications are sent through Resend.

A JavaScript/TypeScript SDK is available for integration. License validation is done through a REST API with API key authentication.

LicenseGate stores only the data necessary for license management: email addresses, license keys and activation information. All data is stored GDPR compliant on European servers.

Payment data is processed exclusively by Stripe.
