Closest first, by how much each site’s offer resembles Codewars’s. Trackers are counted the same way as above. Highlighted technologies are ones Codewars uses too. Votes and comments come from visitors and don’t change the order.

04 · History

No changes yet. Each new crawl is compared with the last one, and what Codewars adds, drops or rewrites shows up here.

05 · Details

How we measure

Alternatives are matched by what sites actually offer, from their homepages, Wikidata and a summary by Claude, in any language. Trackers and the rest of the stack come from the homepage’s code and DNS records.
