PermitCore helps indie developers and software teams add secure license keys, device activation limits, expiration and revocation, offline and floating licensing, entitlements, customer and reseller portals, payments, and webhooks without building and maintaining a separate licensing system. Developers can integrate through a REST API and SDKs for .NET, Node.js, Python, Java, C++, and PHP. A free plan is available for developers getting started, alongside a three-month free trial for paid features.
