Screaming Frog vs Sitebulb: SEO Crawlers Compared

In this article

Weighing a third option?

Not sure either one fits?

We're PipeRocket, a B2B SaaS specialist. If you want an outside read on which way to go, we'll give you an honest one.

The short answer

Screaming Frog and Sitebulb are the two desktop crawlers most technical SEOs reach for. Both download a site the way a search engine would and surface broken links, redirect chains, duplicate content, and indexability problems. The honest split is philosophy, not capability: Screaming Frog is raw crawl power and near-universal ubiquity, Sitebulb is guided audits, visualisation, and prioritised recommendations.

Choose Screaming Frog Raw crawl power and full control

If you want a fast, infinitely configurable raw crawler, you are comfortable interpreting data yourself, and you need the tool with the deepest community documentation and integrations, Screaming Frog remains the default.

Choose Sitebulb Guided, prioritised, client-ready audits

If you want prioritised hints that tell you what to fix first, polished visualisations and reports, and a guided audit experience that reduces manual interpretation, with an optional cloud/server tier for crawling at scale, Sitebulb is the stronger pick.

Vendor profile

Screaming Frog

Desktop crawler · Windows, macOS, Ubuntu · £199/year licence

The Screaming Frog SEO Spider is a desktop crawler from the UK agency Screaming Frog, and it is the closest thing the technical-SEO world has to a default tool. It downloads a site’s URLs and surfaces virtually every on-page and technical SEO element (response codes, redirect chains, meta data, hreflang, structured data, broken links), then lets you export all of it for analysis. Interpretation and prioritisation are left to the user.

Vendor: Screaming Frog (UK agency)
Platform: Desktop app (Windows, macOS, Ubuntu)
Pricing model: Flat annual licence (£199/year per user)
Public rating: 4.9 — Capterra (133 reviews); 4.7 on G2 (~84)
Typical users: Hands-on technical SEOs, developers, agencies

Sitebulb

Desktop + Cloud/Server · Windows, macOS · from ~$18/mo (verify live)

Sitebulb is a technical SEO auditing tool that crawls a site and then layers interpretation on top: it groups findings into prioritised “hints,” scores issue severity, and produces visual site-architecture maps and reports designed to be read by humans, including non-specialists. It is available as a desktop app and, for teams crawling at scale, as Sitebulb Cloud/Server.

Vendor: Sitebulb
Platform: Desktop (Windows, macOS) + Cloud/Server (browser-based)
Pricing model: Monthly/annual subscription; separate Cloud/Server tier
Public rating: 4.9 — Capterra (25 reviews); 4.5 on G2 (~13)
Typical users: SEO teams, agencies, in-house specialists wanting guided audits

Pricing — what you'll actually pay

Screaming Frog uses a flat annual licence; Sitebulb uses monthly/annual subscriptions across desktop tiers plus a separate Cloud/Server tier. Figures are as of June 2026; Sitebulb’s desktop prices shift with promotions, so verify on the live pricing page before purchase.

Starting price	£199 / year (annual licence)	From ~$18 / mo (Lite, desktop; verify live)
Free tier / trial	Free: 500 URLs per crawl, feature-limited	14-day free trial (Pro-equivalent, no credit card)

Higher tiers	Single paid licence (unlimited URLs, JS, scheduling, API)	Pro ~$42/mo + per-user; Cloud/Server from ~$245/mo (verify live)

Capability comparison

Both crawl a site from the ground up, so the differences are at the edges: how each surfaces and prioritises issues, reporting and visualisation, and scalability beyond the desktop.

Service	Screaming Frog	Sitebulb
Raw crawl power & configurability	✓ Core strength	✓ Capable
Crawl scale	Bounded by local hardware (DB storage mode)	Up to 500k URLs (Pro); Cloud for scale
JavaScript rendering	✓ Paid licence	✓ Included
Prioritised audit hints	✕ Not offered	✓ Lead differentiator
Issue severity scoring	✕ Not offered	✓ Built in
Data visualisation / crawl maps	Utilitarian	✓ Strong, client-ready
Custom extraction (XPath/CSS/regex)	✓ Paid licence	✓ Offered
API integrations (GA/GSC/PageSpeed)	✓ Paid licence	✓ GA/GSC
Scheduled crawls	✓ Paid licence	✓ Pro / Cloud
Crawl / audit comparison	✓ Paid licence	✓ Pro
Free tier	✓ 500 URLs per crawl	✕ Trial only (14 days)

Decision matrix — who fits which side

Criterion	Screaming Frog	Sitebulb
Raw crawl power and deep configurability	✓	–
Prioritised audit hints and severity scoring	✕	✓

Strengths & tradeoffs

Both are excellent at the core job, crawling a site and surfacing its technical health. The honest differences are at the edges, and each side wins some rows.

Axis	Screaming Frog	Sitebulb
Crawl engine	Fast, infinitely configurable raw crawler	Capable crawler, interpretation layered on top
Issue prioritisation	None; you triage the data yourself	Prioritised hints with severity scoring
Visualisation & reports	Functional, utilitarian	Strong crawl maps, client-ready reports
Documentation & community	Largest in SEO; documented workflow for most cases	Smaller community and review pool
Scale	Bounded by local hardware (DB storage mode)	Pro up to 500k URLs; Cloud/Server for at-scale crawling
Pricing	£199/year flat licence; free 500-URL tier	From ~$18/mo desktop; Cloud/Server materially higher

Ratings & track record

Metric	Screaming Frog	Sitebulb
Capterra rating	4.9 / 5	4.9 / 5
Capterra reviews	133	25
Vendor	Screaming Frog (UK agency)	Sitebulb
Platform	Desktop (Windows, macOS, Ubuntu)	Desktop (Windows, macOS) + Cloud/Server
Typical users	Hands-on technical SEOs, developers, agencies	SEO teams and agencies wanting guided audits

Both tools carry a 4.9 Capterra rating, but on review volume Screaming Frog is well ahead (133 reviews vs 25), which also means a far deeper pool of third-party documentation and community troubleshooting. Sitebulb’s smaller review base is not a quality signal against it; reviewers single out its prioritised hints and visual reports. Weigh raw documentation depth against guided interpretation when deciding which suits your team. For a wider view of the category, see our roundup of the best SEO audit tools .

Both tools’ data is sourced from publicly available information as of June 2026. Pricing, features, and ratings change, and Sitebulb’s desktop prices shift with promotions, so verify directly with each vendor before buying. This comparison is independent; we take no affiliate fees from either.

Frequently asked questions

What is the difference between Screaming Frog and Sitebulb?

Both are desktop SEO crawlers that audit a site’s technical health. Screaming Frog is a raw crawl engine: fast, highly configurable, and built for SEOs who want full data and will interpret it themselves. Sitebulb takes similar crawl data and adds prioritised “hints,” severity scoring, and visual reports, telling you what to fix first and why. Screaming Frog optimises for control and speed; Sitebulb optimises for guided interpretation and presentation.

Is Sitebulb better than Screaming Frog?

Neither is universally better; they suit different workflows. Sitebulb is stronger if you want the tool to prioritise issues and produce client-ready reports without manual assembly. Screaming Frog is stronger if you want maximum configurability, speed, the lowest annual cost, and the deepest community documentation, and you are comfortable interpreting the data yourself. Many agencies use both.

Is Screaming Frog free?

Partly. Screaming Frog offers a free version that crawls up to 500 URLs per crawl, which is enough for small sites or quick checks. Saving crawls, scheduling, JavaScript rendering, custom extraction, and API integrations require the paid licence, which is £199 per user per year (annual, with USD/EUR pricing available) as of June 2026.

Does Sitebulb have a free trial?

Yes. Sitebulb offers a 14-day free trial with Pro-equivalent desktop features and no credit card required, so you can run full audits before committing to a paid plan.

Which tool is better for large websites?

For very large crawls, both can cope, but differently. Screaming Frog uses a database storage mode on the desktop and is bounded by your machine’s resources. Sitebulb’s desktop Pro tier handles up to 500,000 URLs per audit (expandable), and its Cloud/Server tier is purpose-built for crawling at scale across a team, at a meaningfully higher price.

Which is cheaper, Screaming Frog or Sitebulb?

On a like-for-like desktop basis, Screaming Frog’s £199/year licence is typically cheaper over a full year than Sitebulb’s monthly desktop subscriptions, and Screaming Frog’s free 500-URL tier has no Sitebulb equivalent beyond the 14-day trial. Sitebulb’s Cloud/Server tier is the most expensive option of all. Verify current prices on each vendor’s live page.
