+# Benutzerdefinierte Responseklassen – File, HTML, Redirect, Streaming, usw.
+
+Es gibt mehrere benutzerdefinierte Responseklassen, von denen Sie eine Instanz erstellen und diese direkt von Ihren *Pfadoperationen* zurückgeben können.
+
+Lesen Sie mehr darüber in der [FastAPI-Dokumentation zu benutzerdefinierten Responses – HTML, Stream, Datei, andere](../advanced/custom-response.md).
+
+Sie können diese direkt von `fastapi.responses` importieren:
+
+```python
+from fastapi.responses import (
+    FileResponse,
+    HTMLResponse,
+    JSONResponse,
+    ORJSONResponse,
+    PlainTextResponse,
+    RedirectResponse,
+    Response,
+    StreamingResponse,
+    UJSONResponse,
+)
+```
+
+## FastAPI-Responses
+
+Es gibt einige benutzerdefinierte FastAPI-Responseklassen, welche Sie verwenden können, um die JSON-Performanz zu optimieren.
