About

NexusBro is an AI-powered website QA and audit tool for founders and developers shipping without a QA team. Paste any URL and it returns a full audit in about 30 seconds: 125+ QA and SEO checks per page, covering technical SEO, page speed, accessibility, broken links, security and code quality. It crawls the whole site rather than a single page, up to 10,000 pages. The part that closes the loop: most audit tools stop at a report. NexusBro turns each finding into an actionable fix prompt you can paste straight into your AI coding editor, with the context needed to apply it. The first scan needs no signup and no card. Your data stays private.
