Awesome list of open-source startup alternatives to well-known SaaS products

It is actually a list of startups "strongly basing their product on an open-source repo", that were founded in the last 10 years, that are present on GitHub and that have at least 100 stars (because whatever is not on GitHub does not exist, and social features are so important, I suppose?).

That's quite different (to me, at least) than "open source alternatives to popular services".

Title should read:
