Prefect Community

Hi, someone know if there is a way of installing just the core of Prefect Orion, without the REST API, UI, CLI, just the python API? Thanks in advance.

what are you trying to do? can you explain your use case?

by default when you run:
```pip install -U "prefect&gt;=2.0b"```
it will install just the Python client and CLI with the _option_ to start a self-hosted API Server using:
```prefect orion start```
API Server is optional and you can totally only use the Python client with the ephemeral API if you choose so

We want to use just the Python API (flows, tasks, task runners), and run the flows from local always. I understand that the API Server is optional, but the packages are installed anyway if we use it or not

if you prefer to build something custom, you can clone the repository and extend it as you choose, it's an OSS package - the code is here <https://github.com/PrefectHQ/prefect/tree/orion>

I don’t think you can decouple them because calling a flow hits the API and write to the DB by default
