Dual License Model • Open source under AGPL-3.0 • Commercial licenses for private code • Transparent pricing
Overview
Custom Fields uses a dual licensing model designed to support both open source projects and commercial applications. This approach ensures the project remains sustainable while providing flexibility for different use cases.Open Source (AGPL-3.0)
For open source projects and those willing to share code
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).
Key AGPL-3.0 Obligations
When using Custom Fields under AGPL-3.0, you must:- Share Source Code: Make your entire application’s source code available under AGPL-3.0
- Include License: Preserve all copyright and license notices
- State Changes: Document any modifications you make
- Network Disclosure: Provide source code even for network/SaaS usage
- No Additional Restrictions: Cannot add terms that restrict others’ AGPL rights
