License Zero

= "Tired of seeing your open code end up in closed systems, with no contribution or support flowing back? License Zero puts the teeth back in copyleft, requiring community members to give back to Open Source or support those who do".

Description

"Noncommercial users of noncommercial projects, and Open Source users of reciprocal projects, don’t need any special permission to use License Zero software. For them, License Zero code works like Open Source under two-clause BSD, MIT, or a similarly permissive license.

Customers who want permission for commercial or non-Open Source uses can identify, price, and buy licenses for all License Zero dependencies of their Node.js projects, in one checkout transaction, using a free command-line tool."
