Open-source startups by category.
The 25 product categories in the directory, largest first. The category comes from Jev, TypeSafe’s classifier, which reads a repository’s own name, description and homepage and picks the one category that fits best — so this is a judgment about each project, not a tag its maintainers chose. Projects the classifier could not place in any category are left out rather than filed under a guess.
