The short version
- Screaming Frog gives you the most crawl control available anywhere, and hands you a spreadsheet. Sitebulb gives you less control and explains what it found.
- Screaming Frog is €245 per licence per year with a free 500-URL tier. Sitebulb does not publish desktop prices; Cloud starts from £95/mo.
- If you interpret crawls yourself, Screaming Frog. If someone else has to read the output, Sitebulb.
- Many technical SEOs own both, because they are genuinely complementary rather than substitutes.
These two are the serious options for technical SEO crawling, and the choice between them is unusually clean because they optimise for opposite things. Screaming Frog optimises for what an expert can extract. Sitebulb optimises for what a non-expert can understand. Choose based on the investigation and reporting workflow you need.
The practical question is therefore not "which is better" but "who reads the output". That determines the answer more reliably than any feature comparison.
The short answer
Fit for your workflow
Screaming Frog if you read crawls. Sitebulb if you hand crawls to someone else.
Screaming Frog is the better instrument — more configurable, more extractable, cheaper, and with a free tier that fully covers a small site. Sitebulb is the better deliverable — its hints explain why an issue matters and what to do, which turns a crawl into something a client or a developer can act on without you translating it first.
- Technical SEO working alone
- Screaming Frog. The configurability is the product.
- Consultant delivering to clients
- Sitebulb. The report-writing time you save is the whole value.
- Small site, no budget
- Screaming Frog free tier — 500 URLs covers most small sites entirely.
- Agency with several technical staff
- Both. Screaming Frog for analysis, Sitebulb for deliverables.
Pricing
Screaming Frog publishes full pricing including volume discounts. Sitebulb publishes crawl limits and a Cloud starting price but not its desktop plan prices, so we have recorded what the page actually shows rather than a figure from elsewhere.
Screaming Frog states its desktop licence pricing directly. €245 per licence per year, dropping to €209 at twenty or more licences, stated plainly. Sitebulb’s desktop pricing requires you to go further into the purchase flow, which is a small friction but a real one when you are building a budget.
Where each one is genuinely better
Screaming Frog: configurability
Custom extraction with XPath or CSS selectors, granular control over what gets crawled and how, JavaScript rendering configuration, integration with Search Console and analytics data, and the ability to crawl a list of URLs rather than a site. If there is a specific question you need answered about a site, Screaming Frog can usually be configured to answer it.
It also runs locally, which means no crawl-credit meter running while you experiment. For anyone who crawls frequently, that changes how you work — you stop rationing crawls and start using them as a diagnostic reflex.
Sitebulb: explanation
Sitebulb’s hints do not just flag an issue — they explain why it matters, how severe it is, and what to do about it. That sounds like a small difference and is not. The gap between "342 pages have a duplicate title" and "here is why that splits your relevance signals and which 20 pages to fix first" is the gap between a data export and a piece of work.
Audit comparisons over time are the other genuine advantage, making progress legible to people who do not read crawls. For a consultant justifying a retainer, that visualisation does real commercial work.
What neither of them does
Both are diagnostic. Neither changes anything. A crawl finds 340 pages with missing meta descriptions; writing 340 meta descriptions remains entirely your problem, and it is the part that does not happen. Both also see only the rendered output — they cannot tell you that all 340 pages come from one template with one fixable line in it.
That is the structural limit of crawling as a category, and it is why crawl reports tend to repeat quarter after quarter with the same issues on them. See technical SEO vs content SEO for how to stop that cycle.
