Sitebulb Labs

Find out how ready a website is for AI agents—and what to improve next. Sitebulb Labs scans the website you’re viewing for public signals that help AI agents discover, access and understand it. Instead of checking files, page markup and access rules by hand, you get the findings together in one place. Open the extension from your Chrome toolbar to see an overall score, a breakdown by category and a prioritised list of things to fix. Every check explains what was found, why it matters and what you can do about it, with a link to more detailed guidance. The scan looks at areas such as: • Discoverability, including robots.txt and sitemaps • Content that agents can read, including llms.txt, structured data and pages that depend on JavaScript • Rules that allow or restrict AI crawlers • Page structure and controls that affect how agents use a site • Agent-facing protocols, including MCP and API discovery Sitebulb Labs is useful for website owners, developers and SEO teams who want to understand their site’s current setup, find concrete improvements and check the results after making changes. Use the popup for a quick audit, or open the side panel to keep results beside the page as you browse. You can export a scan as Markdown, CSV or JSON to share findings or track your work. Optional emerging checks let you explore newer standards without treating their absence as a fault. Scans run from your browser. Sitebulb does not receive your audit results.
