Privacy Preserving Web Search With Minimal Tracking

via “privacy-preserving query parameter stripping”

Privacy-respecting metasearch — 70+ engines, no tracking, self-hosted, JSON API for AI agents.

Unique: Implements privacy filtering at the network layer (network.py) before requests leave the SearXNG instance, rather than post-processing results. This prevents tracking parameters from ever reaching external search engines, and uses a configurable blocklist of known tracking parameters that can be extended per deployment.

vs others: Unlike browser extensions that strip parameters client-side (vulnerable to server-side tracking), SearXNG strips parameters server-side before requests leave the instance, providing consistent privacy guarantees across all users regardless of client configuration.
