PermitCore

PermitCore helps independent developers, SaaS founders, software vendors, agencies, and product teams add licensing without building and maintaining a separate licensing backend. It provides encrypted license keys, device limits, expiration and revocation, offline and floating licensing, subscriptions, usage-based and perpetual licenses, customer and reseller portals, Stripe automation, a REST API, and SDKs for .NET, Node.js, Python, Java, C++, and PHP. A permanent free plan supports indie developers at the start, while every paid plan includes a three-month free trial. PermitCore charges no commission on software sales and is designed as developer infrastructure rather than another marketplace between vendors and their customers.
