FerretDB
FerretDB is an open-source, MongoDB-compatible database. It speaks the MongoDB wire protocol, so existing drivers, mongosh and ORMs connect unchanged, and it stores the documents in PostgreSQL through the DocumentDB extension. This template deploys FerretDB 2.7.0 with the matching DocumentDB-enabled Postgres 17, authentication on, a generated password and a volume for the data. Nothing needs filling in.
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.
