FastGPT Open Source License Overview
The FastGPT project is distributed under the terms of the Apache License 2.0, with two specific additional conditions applied to all deployments. All remaining rights and restrictions are governed by the full text of the Apache License 2.0. The product’s interaction design is protected by design patents, and all copyrights are held by Sealos © 2023.
Permitted and Restricted Commercial Uses
Commercial use of FastGPT is explicitly allowed, including use cases such as operating as a backend-as-a-service for third-party applications or as an enterprise app development platform. However, a separate commercial license is required if either of two specific conditions are satisfied. First, operating a multi-tenant SaaS service similar to fastgpt.io using the fastgpt.io source code without explicit written authorization from FastGPT. Second, removing or modifying the logo or copyright information displayed within the FastGPT console. No commercial license is needed for commercial deployments that do not meet either of these two criteria.
Step-by-Step Commercial License Eligibility Check
Follow this structured workflow to determine if a commercial license is required for your FastGPT deployment:
- Classify your intended use of the FastGPT source code.
- If your use is non-commercial, no additional license is needed beyond the standard Apache License 2.0 terms.
- If your use is commercial, verify whether either of the following applies:
- You are operating a multi-tenant SaaS service modeled after fastgpt.io using the official fastgpt.io source code
- You intend to remove or alter the logo or copyright information present in the FastGPT console interface
- If neither condition is met, standard Apache License 2.0 terms apply to your commercial deployment.
- If either condition is satisfied, a commercial license is required before proceeding with deployment.
Contributor License Terms
As a contributor to the FastGPT project, your submitted code is licensed for specific additional uses beyond the base Apache License 2.0 terms. Maintainers retain the right to adjust the open source license for the project to either more restrictive or more permissive terms at their discretion. Additionally, contributed code may be used for commercial purposes, including deployment as part of FastGPT’s official cloud service.
