FastAPI Cloud is the primary sponsor and funding provider for the *FastAPI and friends* open source projects. ✨

## Deploy to other cloud providers { #deploy-to-other-cloud-providers }

FastAPI is open source and based on standards. You can deploy FastAPI apps to any cloud provider you choose.

    for item in items:
        yield item
```

## Server-Sent Events (SSE)

To stream Server-Sent Events, use `response_class=EventSourceResponse` and `yield` items from the endpoint.

Plain objects are automatically JSON-serialized as `data:` fields, declare the return type so the serialization is done by Pydantic:

```python
from collections.abc import AsyncIterable

from fastapi import FastAPI

                return false;
            }
            CombinationItem that = (CombinationItem) o;
            return Objects.equals(stringPart, that.stringPart) && Objects.equals(digitPart, that.digitPart);
        }

        @Override
        public int hashCode() {
            return Objects.hash(stringPart, digitPart);
        }

        @Override
        public String toString() {
