licensor.directory

A living registry of licenses, permissions, and grants — catalogued with care.

What We Catalog

001

Software Licenses

From permissive to copyleft, every open-source license mapped and cross-referenced.

002

Creative Commons

The full spectrum of creative permissions, from attribution to share-alike.

003

Data & API Licenses

Database rights, API terms, and data governance frameworks documented.

004

Hardware & Design

CERN OHL, Solderpad, and emerging hardware licensing standards.

The Registry Method

Indexed

Every license receives a unique registry mark, cross-referenced by type, permissions, and lineage.

Compared

Side-by-side compatibility matrices reveal which licenses harmonize and which conflict.

Traced

License genealogies mapped — see how BSD begat MIT, how GPL forked into LGPL and AGPL.
