SSPL 1.0
Server Side Public License (SSPL) 1.0
Source-available / restrictedSPDX:
SSPL-1.0ScanCode: Source-availableIn one sentence
The source is published, but the license restricts what you may do with it. This is not open source, and the restriction is usually aimed squarely at commercial use.
Using SSPL-1.0 code
You can
- Read the source, and generally use it internally or for development and testing
- Modify it for uses the license actually permits
You must
- Read the specific restriction before you build on it — competing-service clauses (SSPL), change dates (BUSL), and non-commercial limits all behave differently
- Check your company's policy: most treat these as blocked by default
You cannot
- Assume OSI-style freedoms — offering it as a service, or shipping it commercially, is what these licenses exist to prevent
- Treat it as interchangeable with the permissive license the project may have used previously
This is not legal advice. Your obligations depend on how you use the code and your jurisdiction. Consult counsel for production risk.
