cl0q — free & open-source search

A search engine powered by a community network of crawlers indexing thousands of sites a day — and we never log what you search.

What is cl0q?

cl0q is a free and fully open-source search engine. Instead of running on one company's servers, cl0q is powered by a distributed network of crawlers 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 code, running on your own machine with your own private index. No lock-in, no fees, no black box: you can read 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 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. crawl index search The open web billions of pages Crawler network community-run cl0q index full-text, ranked Your results in milliseconds 🔒 Searches are processed in memory — never logged
1

Crawl

A network of community-run crawlers continuously fetches and parses pages from across the web, pulling titles, descriptions, links and metadata.

2

Index

Those pages are normalized, enriched with DNS & network data, and stored in a full-text index ranked for relevance.

3

Search

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. 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 — run by people like you — to discover and refresh the thousands of sites we index each day. The more crawlers, 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:
