It depends.
At least one of these (`Server Side Public License 1.0`) is a source-available license, not OSI-approved open source. Combination terms depend on the specific clauses of the source-available license — review the upstream's FAQ and consult a lawyer before redistributing or running as a service.
| License | Family | Patent grant |
|---|---|---|
| Beerware License (Beerware) | permissive | No (implicit at most) |
| Server Side Public License 1.0 (SSPL-1.0) | source-available | No (implicit at most) |
Beerware License: Joke license: 'if we meet someday, you can buy me a beer.' Not legally rigorous.
Server Side Public License 1.0: MongoDB's source-available license; targets SaaS providers with strong copyleft over the entire service stack.
If you found this page because you're trying to figure out whether shipping a particular dependency is safe, the answer above is a starting point — not a substitute for reading the actual licenses or talking to a lawyer when stakes are high.
