What is Sitebulb?
Sitebulb is a website crawler for technical SEO audits, sold as a desktop app for Windows and Mac and as a browser-based cloud service. Made by Sitebulb Limited in Kent, UK, it checks more than 300 issues and turns them into prioritized Hints that explain what is wrong and why it matters. This guidance makes it popular with agencies that need to explain findings to clients.
Sitebulb Desktop crawls up to 500,000 URLs per audit on the Pro plan, with JavaScript crawling included. Sitebulb Cloud handles up to 10 million URLs per audit and lets teams work on the same crawl data together. Both connect to Google Search Console, GA4, Google Sheets and Looker Studio, and a Sitebulb MCP server links crawl data to Claude and ChatGPT.

Sitebulb FAQ
Is Sitebulb free?
Sitebulb does not have a permanent free plan. It offers a fully featured 14-day free trial, equivalent to Desktop Pro, with no credit card required. After that you choose Desktop Lite, Desktop Pro or Sitebulb Cloud depending on crawl size and whether your team needs shared access. Purchase orders are accepted for yearly plans.
What is Sitebulb used for?
Sitebulb is used for technical SEO audits. It crawls a website, checks for more than 300 issues, and explains each one through prioritized Hints. Agencies and in-house teams use it to find problems, compare audits over time and produce client-ready reports and visualizations.
Sitebulb vs Screaming Frog: what's the difference?
Both are popular technical SEO crawlers. Screaming Frog offers a free 500-URL version and a low annual license with very granular data. Sitebulb focuses on explaining and prioritizing issues, with stronger visual reports and a cloud option for large sites and team collaboration. Teams often pick based on reporting style and budget.
Does Sitebulb work on Mac?
Yes. Sitebulb Desktop installs on both Windows and Mac. If you prefer not to crawl from your own machine, Sitebulb Cloud runs in a web browser, handles much larger sites and lets several team members work on the same audit data. Extra users can be added to Desktop Pro for a monthly fee.
Is Sitebulb good for beginners?
Sitebulb is one of the friendlier technical crawlers for beginners. Its Hints explain each issue, why it matters and how to fix it, and results are prioritized so you know where to start. The Lite plan keeps costs down for smaller sites while you learn.
