Problem
Many applications rely on MongoDB as a document database, but users may encounter vendor lock-in and licensing restrictions that limit flexibility and control. Migrating away from MongoDB can be a complex and costly undertaking.
Solution
FerretDB is an open-source, MongoDB-compatible database that uses PostgreSQL or SQLite as a backend, allowing users to leverage existing MongoDB drivers, tools, and UIs without being tied to MongoDB's proprietary ecosystem. By acting as a proxy between MongoDB drivers and a SQL database, FerretDB enables developers to use familiar MongoDB syntax while benefiting from the robustness and flexibility of open-source relational databases. This approach allows for seamless integration with existing PostgreSQL infrastructure and avoids the need for extensive code modifications during migration.
Target Audience
FerretDB targets developers and organizations currently using MongoDB who seek an open-source alternative to avoid vendor lock-in or those looking to integrate document-oriented data with existing PostgreSQL infrastructure.
