Our top 1 Exa alternatives
SearXNG is a metasearch engine written in Python. Instead of crawling and indexing the web itself, it queries other search services and databases, merges what they return, and presents a single result set through its own interface. The project describes itself plainly: users are neither tracked nor profiled. It is licensed under the GNU Affero General Public License (AGPL-3.0), and its documentation lives at docs.searxng.org.
