Best Swimm Alternatives
Looking for a Swimm alternative? Swimm is docs that live next to your code and flag themselves as stale in CI when the code moves on without them. That's a good fit for plenty of teams, but not everyone — here are 6 real documentation tools worth comparing it against, each with an honest take on what it does differently. ReadMe is the one people mention most: if your product is an API, this turns your OpenAPI spec into docs devs can actually test requests against. Mintlify is another solid option — point it at a GitHub repo and get a polished, AI-searchable docs site without touching a CSS file. None of these are ranked by who pays the most to be listed first; they're ordered the same way the rest of this directory is, sponsors aside.
