Website crawler and technical SEO auditing tool, available on desktop and in the cloud

Sitebulb is a website crawler and technical SEO auditing tool made by Sitebulb Limited, a UK company founded by Patrick Hathaway and Gareth Brown. It launched in 2017 and is used by SEO consultants, agencies and in-house teams who need to audit and explain technical issues on websites of any size.

The tool crawls a site and produces audits covering indexability, internal linking, duplicate content, page speed, structured data and other technical factors, with issues grouped and prioritised so they can be passed to developers and clients. The desktop version runs on Windows or Mac and handles crawls of up to 500,000 URLs by default, which can be raised to two million depending on the machine. Sitebulb Cloud runs in the browser, does not depend on local hardware and is aimed at very large sites and teams that share crawl data, with unlimited projects and automated recurring crawls.

Desktop plans come in Lite (up to 10,000 URLs per audit) and Pro (up to 500,000 URLs per audit, with extra seats available), and a 14 day free trial of Pro needs no credit card. Cloud plans are for two or more users.
