What is cl0q?
cl0q is a free and fully open-source search engine.<br>Instead of running on one company's servers, cl0q is powered by a distributed network of crawlers<br>that together index thousands of new websites every day .
Use it right here on cl0q.com, or self-host the whole stack in minutes with Docker — the same<br>code, running on your own machine with your own private index. No lock-in, no fees, no black box: you can read<br>and run every line.
How the engine works
cl0q turns the open web into searchable results in three stages — and your query never gets stored along the way.
How cl0q works<br>A community network of crawlers fetches and parses pages from the open web, cl0q builds a ranked full-text index, and your search returns results in milliseconds without ever being logged.

Searches are processed in memory — never logged
1Crawl<br>A network of community-run crawlers continuously fetches and parses pages from across the web, pulling titles, descriptions, links and metadata.
2Index<br>Those pages are normalized, enriched with DNS & network data, and stored in a full-text index ranked for relevance.
3Search<br>You type a query and get ranked results in milliseconds — handled in memory and immediately discarded.
We don't log your searches
Privacy is the default, not an upsell. cl0q has no user accounts, no tracking cookies, and no search history .<br>We rely on our network of crawlers to gather the index ahead of time, so answering your query never requires storing it.
Queries are processed in memory and then discarded — never written to a database.
No profiles, no behavioral ad targeting, no cross-site tracking.
The code is open source, so these claims are auditable.

Join the crawler network
cl0q's index is only as strong as the network behind it. We rely on a community of crawlers —<br>run by people like you — to discover and refresh the thousands of sites we index each day. The more crawlers,<br>the broader and fresher the search.
Want to help keep the open web searchable? Run a crawler and contribute pages to the shared index. Come say hi and get set up:
