Sell your software with licenses that just work

Atlas issues license keys, limits how many devices can use them, and lets your app check them in one call. Start with the quick start, or jump to what you need.

How it works

Issue

Create a license by hand, from your checkout, or automatically from a storefront.

Activate

Your customer enters the key and your app activates their device.

Check

On each launch your app validates the license and unlocks the features it includes.
