Sitebulb is a UK-built desktop and cloud SEO crawler. Compare 2026 pricing, features, pros and cons for this technical SEO auditing tool.
Sitebulb was founded in 2017 by Gareth Brown and Patrick Hathaway and is based in Biddenden, Kent, United Kingdom. It was built to make technical SEO audits more approachable, pairing raw crawl data with plain-language, prioritized recommendations rather than leaving practitioners to interpret spreadsheets unaided.
The product ships in two forms: Sitebulb Desktop, a native app for Windows and Mac that crawls sites using the user's own machine and bandwidth, and Sitebulb Cloud, a browser-based version that runs crawls on hosted infrastructure for larger sites or teams that need shared access.
Sitebulb remains a small, independently run company with a team of roughly 2 to 10 people, and it has built a strong reputation within the SEO community as a founder-led alternative to larger enterprise crawling platforms.
Sitebulb's audits go beyond raw data by attaching a prioritized 'Hint' to each issue found, explaining what it is, why it matters, and how to fix it, which makes the tool accessible to SEOs who are newer to technical auditing.
The tool renders JavaScript during crawls to reflect what modern search engines actually see, and it generates visualizations such as crawl maps and sunburst diagrams to help users understand site architecture and internal linking at a glance.
Sitebulb supports scheduled recurring audits, integrations with Google Analytics and Google Search Console, white-label PDF reporting for agencies, and API access on higher-tier plans for automating audits into other workflows.
Sitebulb Desktop is sold in two tiers: Lite, starting around $13.50 per month billed annually with a 10,000 URL crawl limit across five projects, and Pro, around $35 per month, which raises the crawl limit to 500,000 URLs.
Sitebulb Cloud is priced separately from the desktop app and scales with crawl volume, starting around $65 per month and reaching approximately $245 per month for the top tier supporting up to 10 million URLs per audit.
A free trial is available, letting prospective customers test crawl and reporting features before committing to either the desktop or cloud subscription tiers.
Sitebulb offers a free trial but requires a paid subscription for ongoing use, split between Desktop and Cloud pricing tiers.
Desktop runs crawls locally on the user's machine, while Cloud runs crawls on hosted infrastructure accessible from a browser, better suited for large sites or teams.
Desktop plans support up to 500,000 URLs per crawl on the Pro tier, while Cloud plans can support audits of up to 10 million URLs.
