CouchDB
Apache CouchDB is the document database that speaks plain HTTP and JSON, with a built-in web console (Fauxton) and master-master replication. It is the usual backend for offline-first apps that sync with PouchDB, and for anything that wants a database reachable with nothing but curl.
Disclosure: deploy links carry the author's Railway referral code — the author receives a usage kickback when you deploy. The template itself is free to deploy; Railway usage charges apply.
