# FerretDB
:::info
- If you setup Komodo using **Postgres** or **Sqlite** options prior to [**Komodo v1.18.0**](https://github.com/moghtech/komodo/releases/tag/v1.18.0), you are using **FerretDB v1**.
- Komodo now uses **FerretDB v2**. For existing users, [**upgrading requires a migration**](https://github.com/moghtech/komodo/blob/main/bin/util/docs/copy-database.md#ferretdb-v2-update-guide).
:::
[**FerretDB**](https://www.ferretdb.com) is a MongoDB-compatible database backed by [Postgres + DocumentDB extension](https://github.com/microsoft/documentdb).
It is a solid option with performance comparable to MongoDB, and can also be run on some systems which [do not support MongoDB](https://github.com/moghtech/komodo/issues/59).
