Licenses

This page divides the licenses that have been reviewed by the Launchpad staff into open and proprietary groups. Licenses that comply with Legal/ProjectLicensing are considered to be open, and the projects that use them are free to use Launchpad. Licenses that do not comply are considered to be proprietary. Projects with proprietary licenses can purchase a commercial subscription or change to an open license.

Open

OSI-approved / FSF-approved
Licenses already approved as free-software / open-source licenses by the Free Software Foundation and the Open Source Initiative are automatically open enough for Launchpad. Any license on one list is usually on the other. If a project wants to use a license approved by one organization but not the other, we'll consider it on a case-by-case basis (but it's incredibly rare that that would come up).
