# Self-hosted engine

The **self-hosted engine** (`assignment-user-matcher`) is the open-source (MIT) Redis-backed matching engine that powers Fivexer. It is the right choice when you want to run routing entirely on your own infrastructure.

For the hosted platform and SDKs, see:

- [Quickstart](/docs/quickstart)
- [SDKs](/docs/sdks)
- [API reference](/docs/api)

The engine documentation on this site is being reorganized. In the meantime, the source README and examples live in the [assignment-user-matcher repository](https://github.com/ViljarVoidula/assignment-user-matcher).
