Sitebulb Review 2026

Sitebulb is a website crawler built for better SEO audits: clearer prioritisation, better visualisations, and a choice between desktop and cloud so you can scale without changing tools. Whether you run one-off technical audits or recurring crawls across large sites, Sitebulb aims to get you to actionable insights faster and help you explain them to clients and stakeholders. This review covers what Sitebulb does, how it’s priced in 2026, who it’s for, and how it compares to alternatives like Screaming Frog and cloud crawlers such as Lumar and OnCrawl.

Quick overview

Product overview

Sitebulb is a website crawler and technical SEO audit tool available as Desktop software and as Sitebulb Cloud. The product’s value proposition is “website crawling without compromise”: thorough crawling (including JavaScript), prioritised findings, and communication-friendly outputs so you can find issues and get buy-in for fixes.

Target users and use cases. The tool is aimed at SEO professionals, freelance consultants, in-house teams, and digital agencies. Use cases include one-off technical audits, recurring site health checks, migration audits, international SEO (e.g. hreflang), structured data validation, and client reporting. Desktop fits individuals and small teams; Cloud fits teams that need shared crawl data, very large sites (up to 10M URLs per audit), and scheduled recurring crawls without desktop or project limits. Background and market position. Sitebulb Limited was founded in 2017 and is based in Biddenden, Kent, UK. The company was incorporated in 2019 and is privately held; co-founders include Gareth Brown (CTO) and Patrick Hathaway (CEO). Sitebulb has not raised external funding and operates with a small team. The product has won awards (e.g. Best Search Software Tool at the UK Search Awards) and is used by thousands of SEOs globally; the website states “5,000+ SEOs” as of 2026. Sitebulb Cloud was launched to offer the same audit quality in the browser, with no project limits and no crawl-credit system, and is positioned as a more affordable alternative to legacy cloud crawlers. Desktop vs Cloud. Desktop runs on your machine (Windows or macOS), supports up to 500,000 URLs per audit, and includes a 14-day free trial. Cloud runs in the browser, supports up to 10 million URLs per audit, offers unlimited projects and real-time collaboration, and includes bundled Desktop Pro licences on paid Cloud plans. Both use the same Hints engine and reporting philosophy; Cloud adds scale, scheduling, and team access.

Feature deep dive

Core features

Prioritised Hints. Sitebulb’s audit workflow is built around Hints: a list of 300+ SEO issues and opportunities, organised into 15 categories and by importance (Critical, High, Medium, Low, Insight) and type (Issue, Opportunity, Potential Issue). Each Hint explains what the problem is and why it matters, in language you can copy into reports or tickets. That prioritisation helps you focus on the most impactful fixes first and speeds up audits compared to raw crawl exports. JavaScript crawling. Sitebulb uses an Evergreen Chromium rendering engine, aligned with how Google renders pages. You can crawl sites with JavaScript enabled so you see the same content Googlebot can index. JavaScript crawling is included on every plan at no extra cost and can be toggled on or off. A Response vs Render comparison shows differences between initial HTML and rendered HTML, which is useful for JS-heavy sites. Internal data suggests a growing share of users run crawls with JavaScript enabled. Crawl scale and “all you can eat”. Desktop allows up to 500,000 URLs per audit (subject to your machine). Cloud allows up to 10 million URLs per audit and, on Cloud Server plans, no project limits and no per-crawl credit system—you pay for the plan’s monthly URL allowance. That makes it possible to run many client sites or very large domains without per-project or per-crawl penalties. Audit comparison. You can compare two audits over time to see what changed: new or fixed issues, trends, and progress. Change history is presented in charts that you can use in reports to show stakeholders that technical fixes are having an effect. Reporting and export. You get customisable PDF reports (e.g. executive summary, prioritised Hints for developers, or scores and graphs only), spreadsheet exports, and the ability to tailor reports by audience. Data can be exported to Google Sheets with automatic folder organisation by project and audit, and Cloud users get a Looker Studio connector so dashboards can update as new audits complete. Custom URL explorer. Beyond Hints, you can drill into URL-level data with your own columns, filters, and sorting so you can answer ad-hoc questions and dig into edge cases without leaving the tool.

Advanced and differentiated features

Scheduling and recurring audits. Desktop Pro and Cloud support scheduled and recurring crawls so you don’t have to remember to run them or keep your machine on. Large or small crawls can run on a schedule you choose. Integrations. Sitebulb integrates with Google Analytics, Google Search Console, Google Sheets, Looker Studio, Slack, and webhooks. You can blend crawl data with GSC and GA in Looker Studio for unified reporting. Cloud Server plans support unlimited GA/GSC accounts. There is no broad public API for building custom integrations; the product is oriented around these native connections and export workflows. Accessibility, structured data, and specialist reports. The tool includes accessibility auditing, structured data validation, internal link auditing, XML sitemap analysis, hreflang checks, code coverage analysis, content extraction, and the Response vs Render report. These sit alongside the core crawl and Hints to support technical, international, and content audits. Desktop + Cloud in one subscription. Cloud Server plans include Sitebulb Pro desktop licences (e.g. Small plan includes multiple Pro licences). You can use the desktop app to connect to your Cloud server and switch between local and cloud crawls, giving teams a single subscription for both ways of working.

Integrations summary

• Google Analytics – blend audit data with GA in reporting
• Google Search Console – combine crawl and GSC data
• Google Sheets – export and auto-organise by project/audit
• Looker Studio – direct connector (Cloud) or via Sheets; blend with GSC/GA
• Slack – notifications and workflow
• Webhooks – event-driven automation

Browser extensions or mobile apps are not a focus; the product is desktop app and web (Cloud) based.

Free trial and hidden costs. Desktop has a 14-day full-featured trial. Cloud does not offer a free trial; the company suggests using the Desktop trial to learn the product. There are no per-project or per-crawl fees on Cloud; your limit is the plan’s monthly URL allowance. Yearly billing for Cloud can reduce effective monthly cost; exact discounts are on the pricing page.

Advantages and disadvantages

Advantages

• Prioritised Hints – 300+ issues with clear explanations and severity, so you can tackle the most important items first and copy text into reports or dev tickets.
• JavaScript crawling included – No extra fee on any plan; Evergreen Chromium aligns with how Google renders pages; Response vs Render helps debug JS indexing.
• Desktop and Cloud – One product family: start on Desktop, move to Cloud when you need scale or collaboration without learning a different tool.
• No project limits on Cloud – Crawl as many sites as you need within your plan’s URL allowance; no per-project caps or crawl-credit anxiety.
• Strong visualisations and reporting – Crawl maps, charts, and customisable PDFs make it easier to communicate technical findings to clients and executives.
• Transparent pricing – Plans and limits are published; Cloud is positioned as cheaper than Botify, Lumar, and OnCrawl for comparable scale.
• Support from the product team – Customers get help from the people who build the tool rather than generic account managers.
• Recurring audits and scheduling – Pro and Cloud users can schedule crawls so monitoring stays consistent without manual runs.

Disadvantages

• Desktop-only limits on Lite – 10,000 URL cap and missing Pro features (scheduling, Sheets, advanced reports) make Lite suitable only for small sites or try-before-you-buy.
• Desktop single-machine risk – If your computer fails or is unavailable, the crawl stops; no built-in collaboration on Desktop.
• Cloud cost vs Desktop – Cloud is a step up in price (from ~£95/month); justified by scale and collaboration but not ideal for solo practitioners on a tight budget.
• No Cloud free trial – You have to evaluate via Desktop trial or a sales conversation.
• Hardware limits on Desktop – Very large crawls (e.g. 500k URLs) depend on your machine’s RAM and CPU; Cloud avoids that constraint.

Competitive comparison

Sitebulb vs Screaming Frog. Screaming Frog is the long-standing desktop standard: one-off/annual licence, deep configuration, and a free 500-URL tier. Sitebulb offers a more guided experience (Hints, clear explanations) and optional Cloud. Choose Sitebulb for prioritisation, visuals, and cloud or hybrid workflows; choose Screaming Frog for maximum control and a single annual fee. Sitebulb vs Lumar (formerly DeepCrawl). Lumar is a cloud crawler aimed at enterprise and very large sites. Sitebulb Cloud positions itself as more affordable and easier to adopt, with no project limits and no crawl credits. Choose Sitebulb for cost and simplicity; Lumar for established enterprise processes and scale. Sitebulb vs Botify. Botify emphasises log-file analysis and enterprise integrations. Sitebulb focuses on crawl-based audits, Hints, and reporting. Choose Sitebulb for crawl-led technical audits and client reporting; Botify for log-based crawl budget and advanced enterprise features. Sitebulb vs OnCrawl. OnCrawl offers predictive modelling and data integrations. Sitebulb emphasises Hints, clarity, and straightforward pricing. Choose Sitebulb for prioritised, communicable audits; OnCrawl for specific modelling and integration needs. Sitebulb vs Ahrefs / SEMrush / Moz. All-in-one suites (Ahrefs, SEMrush, Moz) include site audit as one module alongside backlinks, keywords, and content. Sitebulb is crawl- and audit-focused with deeper technical depth and flexible reporting. Choose Sitebulb when technical auditing and client-ready reports are central; choose an all-in-one when you want one subscription for audit plus backlinks and keywords.

Experience and ease of use

Signup and setup. For Desktop, you download the app (Windows or macOS), start the 14-day trial, and enter a URL to crawl. No credit card is required. For Cloud, you choose a plan on the pricing page or book a demo; setup can take up to 24 hours, after which you get a URL (e.g. yoursite.sitebulb.cloud) and can invite team members. Learning curve. The Hints list and categories make it clear what to fix first. The interface is designed so you can move from crawl to prioritised list to exports without deep configuration. Custom URL explorer and filters suit users who want to dig deeper. Overall, Sitebulb is easier to get value from quickly than a raw crawl export, while still allowing detail when needed. UI and design. The product uses a modern, visual layout: colour-coded severity, interactive charts, and copy-pastable explanations. That reduces the need to “translate” technical findings for clients or developers. Help and support. Documentation, hint explanations, and how-to guides are available on the site. Support comes from the team that builds the product. Response times and channels are not specified in public material; the positioning is “helpful support from the people who built the tool” rather than tiered support plans.

User feedback and reviews

Aggregate ratings (as of published sources). On G2, Sitebulb has around 4.5/5 from a moderate number of reviews and is compared to tools like Oncrawl and ContentKing. On Product Hunt, it has received strong community feedback. The company cites 5,000+ SEOs and has won a Best Search Software Tool award (e.g. UK Search Awards). Capterra and similar sites show generally positive sentiment; exact scores may vary by platform and date. What users praise. Reviews and testimonials highlight: intuitive workflow and prioritisation (Hints), time saved on audits and reporting, quality of PDF and client-ready outputs, JavaScript crawling at no extra cost, fixed monthly cost on Cloud without crawl-credit anxiety, and support from the product team. Quotes from the website include agency and in-house SEOs valuing the same crawl data for the whole team (Cloud), reliability of data, and flexibility of the platform. What users criticise or note. There is little public documentation of major complaints. Considerations that come up: Cloud is more expensive than Desktop; Lite is limited; Desktop is single-user and machine-bound; and there is no Cloud free trial, so evaluation is via Desktop trial or a call. By user type. Freelancers and small agencies tend to value Desktop’s price and reporting. Larger teams and enterprises value Cloud’s collaboration, unlimited projects, and cost compared to legacy cloud crawlers.

Who it’s for (and who it’s not)

Best fit

• SEO professionals and consultants who run technical audits and need clear, prioritised findings and client-ready reports.
• Digital agencies that report to clients and want one tool for both auditing and presentation.
• In-house teams that need recurring crawls, audit comparison, and optional collaboration on the same crawl data.
• Teams currently using Botify, Lumar, or OnCrawl and looking for lower cost, no project limits, and no crawl credits.
• Sites from small to very large – Desktop up to 500k URLs per audit; Cloud up to 10M per audit and scalable monthly volume.

Less ideal

• Solo practitioners on a very tight budget who only need occasional small crawls and prefer a single low-cost annual licence (e.g. Screaming Frog).
• Users who need a Cloud free trial – only Desktop has a trial.
• Teams that rely on log-file analysis or niche enterprise integrations that specialist tools provide.
• Unreliable internet – Cloud depends on browser access; Desktop depends on your machine and local run.

Real-world examples

Zoopla. Zoopla, a major UK property site with millions of pages and high traffic, needed to diagnose SEO issues at scale without the cost of their previous enterprise cloud crawler. They adopted Sitebulb Cloud (e.g. 10M URLs per audit) and run full monthly crawls plus weekly and daily sample audits. Benefits they highlight: ability to crawl at scale, intuitive interface for varying experience levels, direct support from the tool’s founders, and easy export for dev tickets and custom column views. Moving Traffic Media. This performance marketing agency (e.g. 5-person SEO team) moved from Sitebulb Desktop to Sitebulb Cloud. Desktop had meant multiple separate crawls per team member and inconsistent settings. With Cloud, the team works from shared crawl data across many client domains. They cite the ability for everyone to work from the same crawl data, faster crawl completion, and scheduled crawls as reasons they are more productive and have a more consistent process. Jon Clark (Managing Partner) is quoted on the Sitebulb site about the impact of shared crawl data and scheduled crawls.

Other published case studies include Cross Border Digital (enterprise customers, distributed team), Polemic Digital (large-site audits without crawl-credit anxiety), and agencies such as Impression and Candour (cost savings vs. legacy cloud crawlers and streamlined audits). These support the positioning of Sitebulb Cloud as a cost-effective, collaboration-friendly alternative to legacy cloud crawlers.

Outlook and considerations

Roadmap and updates. Sitebulb emphasises continuous improvement and customer feedback. The product has added Cloud, Looker Studio connector, Response vs Render, and ongoing Hints and report improvements. Expect further refinements to Hints, integrations, and Cloud plans rather than a fundamental pivot. Risks and considerations. Pricing may change; verify current plans and currencies on the official site. Lite’s 10k URL and feature limits may not suit growing sites. Desktop remains single-user and hardware-limited; Cloud is the path for teams and scale. The company is small and unfunded, which can mean responsive support but also dependency on a single product line—worth considering for long-term tool strategy. Market fit. Demand for technical SEO audits and JS-aware crawling remains strong. Sitebulb’s “no compromise” positioning (Hints, JS included, Desktop + Cloud, transparent pricing) fits teams that want audit depth without enterprise crawler pricing or complexity.

Summary

Sitebulb is a website crawler built for better SEO audits: prioritised Hints, JavaScript crawling included, and a choice of Desktop or Cloud with transparent pricing and no project or crawl-credit limits on Cloud. It suits SEO professionals and agencies who want to find issues quickly and present them clearly, and teams that need scale and collaboration without the cost of legacy enterprise crawlers.

Verdict: 4.5/5 — A strong choice for technical SEO auditing and reporting, with a clear upgrade path from Desktop to Cloud as your needs grow.
