Open, enterprise-grade licensing & distribution

Keygen is a Fair Source software licensing and distribution API, built for developers, by developers. Self-host or try Keygen Cloud today.

Free during development, no upfront commitment

Developer-first

We've designed Keygen's software licensing and distribution API to be easy to use for developers of all skill sets. Use our official SDKs or grab your favorite HTTP client.

keygen.LicenseKey = "C1B6DE-39A6E3-DE1529-8559A0-4AF593-V3"
// Validate the license
license, err := keygen.Validate(fingerprint)
if err == keygen.ErrLicenseExpired {
  panic("license is expired!")
}
if err == keygen.ErrLicenseNotActivated {
  // Activate the license
  machine, _ := license.Activate(fingerprint)
  fmt.Printf(
    "activated machine %s for license %s!\n",
    machine.ID,
    license.ID,
  )
}

Cloud-native

Keygen was born in the cloud. Cloud is in our team's DNA. With Keygen Cloud, we'll handle all the hard stuff while your team focuses on product, not critical infrastructure.

Focus

Let your team focus on product, not in-house licensing and distribution. Save time by using Keygen Cloud as a ready-to-go licensing solution.

Maintenance

Skip the expensive up-front and ongoing costs of an in-house or self-hosted licensing solution. Save your business development time and money with Keygen Cloud.

Scale

Effortlessly go from hundreds of users, to thousands, to hundreds of thousands and beyond. We'll handle the infrastructure so your team can focus on product.

Security

We strive to ensure that data stored within Keygen Cloud is as secure as possible. TLS, HA, continuous backups, data encryption at-rest, in-transit, and at-work.

Enterprise-grade
