FerretDB The MongoDB Drop-In Replacement Is Production Ready

 FerretDB moves your application workloads from MongoDB to PostgreSQL. Why is that big a deal?

FerretDB, previously MangoDB (yes, Mango, this is not a typo!) is:

a stateless proxy, which converts MongoDB protocol queries to SQL, using PostgreSQL as a database engine.
It is compatible with MongoDB drivers, and should work as a drop-in replacement to MongoDB in many cases.
