Licensing as a service

“Licensing as a service” is the same idea that turned servers into cloud and payments into Stripe, applied to licensing. You don’t build the licensing backend; you call one. For most app developers, that’s the right trade — licensing is critical, but it isn’t the product.

What is licensing as a service

Licensing as a service (LaaS) is hosted licensing infrastructure delivered as an API and an SDK. The hard parts — issuing keys on purchase, signing entitlements, tracking device activations, verifying licenses offline, revoking on refund — run as a service. You integrate the SDK and call the API; the provider runs the backend, the uptime, and the cryptography.

It’s the licensing equivalent of using a managed database instead of running your own. The capability without the operations.

Why LaaS instead of rolling your own

Building licensing yourself starts easy and stays expensive. Generating and checking a key is a weekend; the rest is a backend you own forever — offline verification that can’t be spoofed, device-limit enforcement, refunds and revocation, trials, key rotation, and keeping it all running while customers’ apps depend on it.

LaaS turns that into an integration. You get the API and SDK, the signing keys are managed, and the uptime is the provider’s problem. You spend your time on the app instead of the license management plumbing. The full case is in dedicated licensing API.

Hosted vs self-hosted

There’s a spectrum. Self-hosting — an open-source engine you run yourself, like Keygen can be — gives maximum control and full ops responsibility: your servers, your uptime, your security patches. Fully hosted LaaS removes the ops entirely; you don’t run anything. The choice is control versus time. Most teams shipping an app, not a licensing platform, want the time.

Keylight as a licensing service

Keylight is licensing as a service for desktop and AI-native apps. Keys mint on payment. The native Swift SDK activates and verifies them, offline, on launch. Device activations are tracked and enforced. Entitlements ride in an Ed25519-signed lease, readable offline. You don’t run a server, manage signing keys, or maintain a licensing backend — you drop in the SDK and connect your payment provider.

That’s the whole pitch of the model: the licensing layer, as a service, so you ship the app.

Plans start at $19/month, with a free tier. The licensing backend, hosted — drop in the SDK.
