Description

FerretDB is an open-source document database that speaks the MongoDB wire protocol and translates queries to PostgreSQL (DocumentDB extension) or SQLite. Existing MongoDB drivers and tools keep working, while data lives in a genuinely open-source storage engine. FerretDB is the recommended FOSS alternative to MongoDB Community Edition (SSPL).
