Licenses

License Zero publishes and stewards a few kinds of licenses and license-related agreements, all of which are written to be as short and easy to read as possible.

Public Licenses

The kind of thing you see in LICENSE files. Public licenses give everyone permission to use your software, as long as they follow specific conditions. License Zero supports two public licenses:

Parity Public License
requires others to release software they build with your work
Prosperity Public License
limits commercial use of your software to a trial period

Private Licenses

License Zero's main function is to sell private licenses on developers' behalf, as their licensing agent.

Private License
gives a specific person permission to use commercially and build closed source, with limited rights to sublicense others

Relicensing

License Zero developers can offer to relicense their work onto permissive open source terms for a one-time fee.

Relicense Agreement
a form contract for sponsored relicensing of software onto permissive terms

Quotes

Sometimes License Zero developers will find it easier to sell exceptions to their public license, or close a relicensing deal, by sending the company a quote and taking payment by check or bank transfer:

quote a price for relicensing your work on permissive terms
