License Information

License Information

After the trial period you will need a valid license. LakeXpress resolves the license in the following order:

1. LAKEXPRESS_LICENSE environment variable — set this for CI/CD or containerized deployments
2. --license TEXT CLI argument — pass the license content directly
3. --license_file PATH CLI argument — point to a license file
4. Default file locations:
   • ~/.lakexpress/license.lic (Linux/Mac)
   • %APPDATA%/LakeXpress/license.lic (Windows)
   • ./license.lic (current directory)
5. Trial mode — automatic 30-day trial if no license is found

See the CLI Reference for details.
