Commercial License
For proprietary applications and private codebases
Open Source License (AGPL-3.0)
Custom Fields is licensed under the GNU Affero General Public License v3.0, a strong copyleft license designed for network software.What is AGPL-3.0?
The AGPL-3.0 is similar to the GPL-3.0 but includes an additional provision: if you run modified versions of the software on a network server, you must provide the source code to users of that server.Important: AGPL-3.0 requires your entire application using Custom Fields to be open source, including when used as a network service (SaaS, web applications, APIs).

The AGPL-3.0’s key difference from GPL is Section 13: if users interact with your software over a network (web app, API, SaaS), you must provide them with the complete source code. This closes the “ASP loophole” where SaaS providers could use GPL software without sharing modifications.
