About FerretDB
FerretDB is an open-source MongoDB-compatible database engine built on PostgreSQL. It enables developers to run MongoDB workloads using PostgreSQL as the backend, letting them use MongoDB drivers, tools, UIs, and the same query language without rewriting applications.
Key Features
When migrating MongoDB workloads, FerretDB translates MongoDB wire protocol requests into PostgreSQL queries, so teams can keep their existing drivers and tooling while tapping PostgreSQL’s backend features:
MongoDB Driver Compatibility
FerretDB accepts MongoDB wire protocol requests and maps them to PostgreSQL queries, letting apps connect without code changes.
PostgreSQL Backend
All data and queries run on PostgreSQL, benefiting from its storage, ACID transactions, and ecosystem.
Tool and UI Compatibility
Use the same MongoDB-native tools, drivers, and UIs with FerretDB.
Open-Source and Self-Hosted
Fully open-source with community governance and flexible deployment options.
Summary
Best for engineering teams migrating MongoDB workloads, platform teams evaluating PostgreSQL-backed data stores, and operations groups aiming to preserve existing tooling during transition.
