The Dify project uses a combination of the Apache License 2.0, MIT License, and an additional agreement to protect against direct competition with Dify Cloud services.
The Dify project is licensed under the Apache License 2.0, with the following additional conditions:
As a contributor, you should agree that your contributed code:
a. Might be subject to a more permissive open source license in the future.
b. Can be used for commercial purposes, such as Dify's cloud business.
1. Dify is permitted to be used for commercialization, such as using Dify as a "backend-as-a-service" for your other applications, or delivering it to enterprises as an application development platform. However, when the following conditions are met, you must contact the producer to obtain a commercial license:
a. Multi-tenant SaaS service: Unless explicitly authorized by Dify in writing, you may not use the Dify.AI source code to operate a multi-tenant SaaS service that is similar to the Dify.AI service edition.
b. LOGO and copyright information: In the process of using Dify, you may not remove or modify the LOGO or copyright information in the Dify console.
The following components are open source under the MIT license, allowing you to build and develop applications based on them:
- WebApp elements, e.g., web/app/components/share
- Derived WebApp Template projects
Please contact business@dify.ai by email to inquire about licensing matters.
The remaining parts of the project are open source under the Apache License 2.0.
2. As a contributor, you should agree that your contributed code:
With the Apache License 2.0, MIT License, and this supplementary agreement, anyone can freely use, modify, and distribute Dify, provided that:
a. The producer can adjust the open-source agreement to be more strict or relaxed.
b. Can be used for commercial purposes, such as Dify's cloud business.
- If you use Dify solely as a backend service for other applications, no authorization is needed for commercial or closed source purposes.
- If you wish to use Dify for commercial and closed source SaaS services similar to Dify Cloud, please contact us for authorization.
