PublicWWW is a search engine for webpage source code. It lets users search for alphanumeric snippets, signatures, or keywords across HTML, JavaScript, CSS, plain text, and HTTP response headers. It is not a traditional code repository search tool; instead, it indexes the source code of real website pages. The page states an index size of 518,931,502 webpages.
Its main value lies in “source-level internet search.” Users can look up shared Google Analytics IDs, AdSense accounts, WordPress themes, nginx versions, ad network scripts, frontend library references, or specific images/badges, making it useful for discovering related websites, identifying tech stacks, or assessing the exposure of third-party components. The query syntax mentions support for RegEx, ccTLD, and more. Results include snippets, can be sorted by website popularity, support up to 1,000,000 results per request, and can be downloaded as CSV.
PublicWWW provides an API for developers who want to integrate its data. Its terms clearly state that automated data access is only allowed via the API, and prohibit crawling or accessing the website, servers, or databases in non-natural ways. In terms of ecosystem coverage, it spans categories such as ad networks, marketing tools, analytics counters, server technologies, frontend frameworks, embedded components, CMS, and JS/CSS/IMG files. The About page also lists multiple security research and media articles, showing that its data has been used in research on supply chain attacks, cryptomining, Web skimming, and more. Documentation includes examples and use cases, but the crawled content did not show a complete API parameter reference, rate limits, or pricing table.
The pricing model combines free registration with paid subscriptions. Results from the Top 1,000,000 websites are shown for free; after registration, users can view results from the Top 3,000,000 websites; additional results require a paid plan. Different subscription plans come with different limits. The terms state that there is no refund policy, which may be unfriendly for teams that are sensitive to trial-and-error costs.
Its strengths are its distinctive search target, coverage of source code and HTTP headers, and support for API/CSV exports. It is suitable for security researchers, growth marketers, SEO teams, affiliate marketers, website tech stack analysis, and developer research. Downsides include opaque pricing details, closed-source operation with no self-hosting information, strict restrictions on automated access, and support that appears to be mainly email-based.
The crawled content does not provide information about Mainland China access, payment methods, or localization, so this remains unknown. If access or payment is restricted, alternatives such as GitHub Code Search, Sourcegraph, BuiltWith, Wappalyzer, Censys, and Shodan may be worth considering depending on the task.
