Detailed Review
Sitebulb launched in 2017 and is developed by Sitebulb Limited, a company with its registered address in Biddenden, Kent and company registration number 12125600. The product is a crawler in which most of the screen space goes to explanation: every issue is a Hint with a priority, a description of why it matters and a pointer to the affected URLs.
Two editions exist. Sitebulb Desktop runs on Windows or Mac and does the crawling from the user's own computer, while Sitebulb Cloud crawls from the vendor's infrastructure for sites too large for a laptop or for teams that need shared access.
Hints instead of raw tables
Pro lists more than 300 Hints and Lite more than 100. Each Hint sorts into a priority bucket, so a report opens on what to fix first rather than on a spreadsheet of URLs.
The vendor's own pricing FAQ says Pro is the popular plan and Lite is meant for people who audit less often or are not SEO specialists.
Size limits you can read
Lite audits up to 10,000 URLs, and Pro defaults to 500,000 URLs per audit, adjustable up to 2 million at the risk of exhausting the machine. The FAQ states plainly that the practical ceiling depends on the computer's specification.
Pro adds advanced configuration, audit comparisons, scheduled audits and customised PDF reports, which is the client-facing side of the product.
Cloud edition and data
Sitebulb Cloud is listed from £95 a month, for two or more users, with no project limits and recurring crawls. According to the privacy notice, Cloud services are hosted in data centers in the UK and the US, and backups for cloud customers go to AWS S3 in London.
The same notice states that account data is stored in a UK data centre and that third parties outside the EU hold a data processing addendum.
Limitations to Consider
The company is British, so the contracting party sits outside the EU, and the privacy notice says Sitebulb Cloud is hosted in both UK and US data centers. Prices on the pricing page load in the browser and could not be read from the page source. Desktop crawl size is bound by your own computer. For continuous monitoring, Audisto is the better fit.
