Be advised that the firm behind it ("sqliteai") had a nasty history of using non-open source licenses, e.g. Elastic License. I advise against using anything by them for this reason even if this project currently has an open license.
what an embarrassment
We used an Elastic license for some projects to protect our work from being used in SASS without a prior agreement. WASTE is and will always be available with a very permissive license.
I really don't understand why some people prefer to spread hate instead of just asking for clarification first.
