SEO Tools
Sitebulb is a website crawler and SEO auditing tool, available as a desktop app and in the cloud, that turns raw crawl data into easy visuals and prioritized recommendations across 300+ SEO issues. Its 'Hints' system ranks findings by impact, and it ships with JavaScript crawling on all plans, Google Analytics, Search Console, and Google Sheets integrations, Crawl Maps for architecture visualization, duplicate content detection, and scheduled audits with customized PDF reports on the Pro plan. For technical SEO work it competes less with full suites and more with the audit modules inside Ahrefs and Semrush.
Sitebulb is priced well below suite-level audits. Desktop Lite is $18/mo for 1 user with 10,000 URLs per audit, and Pro is $42/mo with 500,000 URLs per audit and extra users from £7/mo, with 15% off yearly billing; Sitebulb Cloud team plans start from £95/month. A free trial is available. Against Ahrefs (Site Audit included from Starter at $29/mo, with crawl credits scaling 100K-500K by plan) and Semrush (audits included in the SEO plan at $117.33/mo billed annually), Sitebulb is the cheapest dedicated crawler, though it does not bring keyword research, rank tracking, or backlink databases.

How does Sitebulb compare to Ahrefs and Semrush?
For pure crawling, Sitebulb is dramatically cheaper: Lite is $18/mo and Pro $42/mo (500,000 URLs per audit), versus Ahrefs Starter at $29/mo (with Site Audit crawl credits) and Semrush's SEO plan at $117.33/mo billed annually, which includes a site audit module. If your only need is technical auditing, Sitebulb's 300+ issue checks, JS crawling, and Hints prioritization deliver the same class of output for a fraction of the suite price.
The trade-off is scope. Ahrefs and Semrush bundle auditing with keyword research, rank tracking, backlink analysis, and (in Semrush's case) AI visibility and content tools, so a team buying either suite gets Sitebulb-level auditing as one module. Sitebulb is also more specialized than generic crawlers in its visual reporting and Crawl Maps, and its free trial makes it easy to test before choosing.
Who should use Sitebulb?
Sitebulb is a fit for technical SEO specialists and agencies that run deep crawl audits as a core service. If you audit large sites (Pro handles 500,000 URLs per audit), need JavaScript rendering, prioritize fixes with the Hints system, and present findings as visual reports, Sitebulb's $18/mo Lite and $42/mo Pro pricing beat buying a full suite for the same job. Ecommerce and news/media sites with big URL counts are the typical use case for the 500K Pro ceiling.
Sitebulb is NOT ideal if you also need keyword research, rank tracking, or backlink analysis, since those are not part of its verified feature set; pair it with a research tool like Mangools ($61/mo) or LowFruits ($20.75/mo yearly), or buy Ahrefs/Semrush as an all-in-one instead.
