What does Keyzy do?

Keyzy is a cloud-based license management service built for software vendors who need to generate, deliver, and validate product licenses without running their own infrastructure. Instead of building a licensing system from scratch, you sign up, define your product and SKUs, and start distributing serial numbers — either manually, through a WooCommerce store, or via a REST API. The platform handles the rest: activation, validation, and copy protection.

What makes Keyzy stand out is its focus on simplicity and offline support. The C++ static library lets you embed licensing directly into your binary, with semi-online and fully offline activation modes — useful for desktop software that can't always reach the internet. The dashboard groups products, licenses, activations, and dealers in one place, and the WooCommerce plugin automates license delivery when a sale happens. Pricing starts at free for up to 20 licenses, with paid plans scaling to thousands.

Keyzy is best suited for small to medium-sized software companies and independent developers who want a straightforward licensing solution without the overhead of self-hosting. It's especially useful if you sell through WooCommerce, need offline activation for a C++ application, or distribute through resellers and want a single dashboard to manage everything.
