description: Database systems available on your serverlet.
---

On our serverlet, you can run several database systems. The following databases are currently pre-installed and supported:

## Supported databases

- [Redis](/docs/serverlet/databases/redis/) — a fast key-value database suited for caching and primary data storage
- [MariaDB](/docs/serverlet/databases/mariadb/) — a relational database system, a fork of MySQL
- [PostgreSQL](/docs/serverlet/databases/postgresql/) — an advanced open-source relational database system
- [MongoDB](/docs/serverlet/databases/mongodb/) — a NoSQL document database

All of these databases are pre-installed and ready to use. See the individual pages for detailed information about each one.

## Other databases

Other software can be deployed as static Linux AMD64 binaries with the necessary libraries — see [Runit](/docs/serverlet/runit/) for how to add your own software to a serverlet.
