Foliox License is a software license key system: generate keys, lock each to one device (HWID), set expiry, revoke instantly and verify over a signed API. Free plan, SDKs for Python, Node.js, Go and Rust.
I built Foliox License because I wanted a simpler way for developers to add proper licensing to their software without building the entire licensing infrastructure themselves.
The idea started with a simple problem: how do you issue a license, make sure it's tied to the intended machine, verify it securely, and still have the ability to revoke it if a key gets leaked?
Foliox currently handles HWID-based device locking, license expiration, instant revocation, and Ed25519-signed verification responses. I've also built SDKs for Python, Node.js, Go, and Rust so developers can integrate it into their existing projects.
I'm still improving the platform, so I'd especially love feedback on the API design, security model, SDK experience, and anything that feels confusing or missing.
If you're building desktop software, SaaS tools, paid scripts, or developer products that need licensing, I'd love to hear how you're currently handling it.
