Keygen is a comprehensive Fair Source software licensing and distribution API designed for developers. It provides robust solutions for adding license key validation, device activation, and entitlements to any software product, alongside securely delivering software artifacts and offering automatic updates to licensed users.

Targeting software businesses of all sizes, from F1000s and AI startups to SMBs and independent developers, Keygen supports a wide array of applications including desktop programs (Mac, Windows, Electron, Tauri), mobile apps (iOS, Android), container images, WordPress plugins, and various language packages (Python, PHP, Node, RubyGems).

Key Features

• Software Licensing API: Implement license key validation, device activation, and entitlement management.
• Software Distribution API: Securely deliver artifacts and provide automatic updates to users.
• No-code Licensing Automation: Integrate with tools like Stripe and Postmark via Zapier for streamlined workflows.
• Flexible Deployment: Choose between Keygen Cloud or self-host the free Community Edition (CE) or Enterprise Edition (EE).
• Offline Licensing: Utilize Keygen Relay for secure node-locked licenses in air-gapped environments.
• Developer-first Tools: Official SDKs, CLI, and comprehensive documentation for easy integration.

Use Cases

Keygen significantly reduces the development time and complexity associated with building in-house licensing solutions. For instance, a software company can integrate Keygen to manage subscriptions and activations for their desktop application, ensuring only licensed users can access features and receive updates. This frees up engineering teams to focus on core product development rather than critical infrastructure.

Beyond licensing, Keygen facilitates secure software distribution. Developers can use its API to push new versions of their applications or plugins, which are then automatically delivered to licensed users, ensuring a seamless update experience. This is particularly beneficial for maintaining security patches and new feature rollouts across a large user base.

The no-code automation capabilities allow businesses to connect Keygen with their existing payment and communication platforms. For example, when a customer purchases a license via Stripe, Keygen can automatically generate and issue a license key, and Postmark can send a transactional email, all without requiring custom code.

Pricing Information

Keygen operates on a freemium model. It is free to use during development with no upfront commitment. The Community Edition (CE) is also free to self-host for both personal and commercial projects, making enterprise-grade licensing accessible to everyone. Keygen Cloud and the Enterprise Edition (EE) offer additional features and managed services for businesses requiring advanced capabilities.

User Experience and Support

Designed with developers in mind, Keygen offers a "developer-first" experience with easy-to-use APIs, official SDKs, and a CLI. Extensive documentation, an API Reference, and a Changelog are available to guide users. Community support is provided via GitHub and Discord, and users can also chat 1-1 with a Keygen engineer via Slack for direct assistance.
