Licentivo is a hosted software licensing API, dashboard and set of SDKs for desktop software. It covers license checks, device binding, floating (concurrent) seats with lease timeouts, offline activation through request and response files, perpetual, time-limited and trial license types, feature IDs with monthly usage limits, and upgrade eligibility.
Official SDKs cover Go, Java, C, C++, C#, Python, JavaScript, Rust and Ruby, and the C# guide mentions WinForms. Buyers get a customer portal to view licenses and release devices. The site has documentation, a changelog, a console sign-up and a live demo that needs no sign-in. Plan prices are shown on its pricing page without signing in.
Licentivo was built to bring software licensing rules and integration into one workflow, so developers can add activation, device limits, offline access and feature permissions to their own desktop apps, with SDK examples to help the first setup.
