cl0q

cl0q is a free, independent search engine. Instead of reselling another search engine's results, it runs its own crawler and its own full-text index, adding thousands of new websites every day with a stated goal of reaching 100 million sites in the index. Searches are used without an account, and the site says it does not store search logs: queries are processed in memory and then discarded, with no cookies, search history, or behavioral ad targeting.

The engine works in three stages. Its own crawlers fetch and parse pages from the open web at most one request per second to any server, cl0q builds a ranked full-text index enriched with DNS and network data, and search returns ranked results in milliseconds. The search page also offers power operators for exact phrases, site and TLD filtering, title and URL matching, and infrastructure lookups such as IP, CNAME, ASN, and hosting organization, which can be combined.

The project is aimed at people who want a search engine that is independent of other providers and that keeps no record of what they search. It also suits people who want to explore the web's infrastructure through network-level pivots. Accounts are optional and passkey-only, and only used for community features.

What sets cl0q apart is its stated plan to go open source. Once the code is published, users will be able to read it and run their own copy. A contributor program in early access lets others run crawler nodes that add pages to the shared index; the crawler node code is published on Codeberg, and nodes are currently set up by hand.
