About Mwmbl
Mwmbl is a non-profit, open-source search engine that aims to replace commercial engines such as Google and Bing with a community-run alternative. It promises no ads, no tracking, and no profit, and it lets the community determine rankings. The code is written in Python and released under the AGPL-3.0 license.
The index is centralized, but the crawling is distributed across servers run by volunteers, who also help curate search results. The README is candid that the index is currently much smaller than those of commercial search engines and invites people to help it grow by contributing crawling capacity.
The main community gathers on Matrix, with a Discord server for non-development discussion. Mwmbl suits privacy-minded users and developers who want to experiment with independent search, and who are willing to accept more limited coverage in exchange for a transparent, non-commercial project.
