# Screaming Frog vs Sitebulb Source: https://piperocket.digital/compare/screaming-frog-vs-sitebulb/ Author: Sabari Rohith, Sr. SEO Specialist, PipeRocket Digital Reviewed by: Kamaraj Mathiarasan (Kim), Co-Founder, PipeRocket Digital Published: 2026-06-19 Last updated: 2026-07-15 Two of the most-used technical SEO crawlers, compared honestly: crawl power, audit prioritisation, visualisation, pricing, ratings, and which fits your workflow. ## 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. ## At a glance | | Screaming Frog | Sitebulb | |----------------------|----------------------------------|--------------------------------------------------| | **Vendor / founded** | Screaming Frog (UK agency) | Sitebulb | | **Platform** | Desktop (Windows, macOS, Ubuntu) | Desktop (Windows, macOS) + Cloud/Server | | **Starting price** | £199 / year (annual licence) | From ~$18 / mo (Lite, desktop; verify live) | | **Public rating** | 4.9, Capterra (134 reviews) | 4.9, Capterra (25 reviews) | | **Best for** | Raw crawl power and full control | Guided, prioritised audits with visual reporting | ## 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 (134 reviews); 4.7 on G2 (~186) - **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. | | Screaming Frog | Sitebulb | |-----------------------|-----------------------------------------------------------|------------------------------------------------------------------| | **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) | | **Licence model** | Flat annual per-user licence | Subscription (~15% off annual) | | **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) | | **Community / documentation depth** | ✓ Largest in SEO | Smaller community | ## Decision matrix, who fits which side | Criterion | Screaming Frog | Sitebulb | |----------------------------------------------|----------------|----------| | Raw crawl power and deep configurability | ✓ | \- | | Prioritised audit hints and severity scoring | ✕ | ✓ | | Client-ready visualisation and reports | \- | ✓ | | Lowest annual cost | ✓ | \- | | Free tier (no time limit) | ✓ | ✕ | | Deepest community documentation | ✓ | \- | | Guided interpretation for non-specialists | \- | ✓ | | Purpose-built cloud scale for teams | ✕ | ✓ | *Check = clear edge.

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 | 134 | 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 (134 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.

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. ## Sources and references 1.
