About Webmaster Bench
Webmaster Bench is a small set of free tools for people who look after websites: developers, SEO specialists, content editors and site owners. Each tool does one job (testing robots.txt rules, validating a sitemap or feed, checking hreflang or structured data, reading HTTP headers or crawler logs) and explains its result.
How it is made
The site is built and maintained by an independent publisher with substantial help from AI (Anthropic's Claude), which writes much of the code and the first drafts of the explanations. Every tool's logic is covered by automated tests built from the worked examples you see on the pages, and every page is tested in a real browser before it is published. The explanations are checked against the primary sources they cite: the IETF RFCs, the sitemaps.org protocol, the RSS and Atom specifications, and Google's Search Central documentation.
That does not make the tools infallible. Search engines change their behaviour, and specifications leave room for interpretation. Where a tool follows one crawler's interpretation (usually Google's), the page says so. If you find a mistake, please tell us at contact@webmasterbench.com; corrections are welcome and are made quickly.
There is no team page and there are no testimonials here, because we would rather not invent them.
Your data
All tools run in your browser. What you paste or open is processed on your device and is not uploaded, stored or logged by us. See the privacy policy for the details, including what our hosting provider and (when shown) advertising partners process.
How the site is paid for
The site is free to use. It is funded by advertising, shown in clearly marked spaces, and by a few paid data tools that we publish on the Apify platform for jobs a browser cannot do, such as checking thousands of live URLs or extracting every URL from a site's sitemaps. Tool pages mention those only where they are relevant, and say plainly that they are ours and paid.
