LicenseForge — License Key Generator & Validator

Build your own software licensing system in minutes. LicenseForge generates professional license keys with built-in tier encoding (free/basic/pro/enterprise), expiry dates, feature flags, and HMAC cryptographic validation. Keys look like XXXX-XXXX-XXXX-XXXX — clean and professional.

Batch generate hundreds of keys for distribution. Validate keys with one command. Revoke compromised keys from a JSON database. Every key is self-contained — the tier, expiry, and features are encoded directly in the key itself.

Single Python file. Zero dependencies. Python 3.8+. Your licensing infrastructure in 10KB.
