Herein you will find some hints and suggestions about typical architectures of SearXNG infrastructures.

uWSGI Setup¶

We start with a reference setup for public SearXNG instances which can be build up and maintained by the scripts from our DevOps tooling box.

The reference installation activates server.limiter, server.image_proxy and ui.static_use_hash (/etc/searxng/settings.yml)
