What Is NexusBro QA?
NexusBro is an AI-powered website quality assurance tool that audits any site for performance bottlenecks, SEO issues, accessibility gaps, security misconfigurations, and code quality problems. Paste a URL, select your audit categories, and receive a comprehensive fix-ready prompt you can run in your preferred AI coding tool to resolve every issue found.
Traditional QA is slow and expensive. Manual testing across performance, SEO, accessibility, security, and code quality can take days for a single site. NexusBro automates the entire process: it crawls your pages, runs hundreds of checks per page, identifies real issues with severity rankings, and generates actionable fix instructions. The result is a detailed prompt that works with Claude Code, Windsurf, or any AI coding tool.
Free users get 5 audits per day covering up to 10 pages each. Pro unlocks 50 audits per day with up to 250 pages per audit. Pro Max gives unlimited audits with up to 10,000 pages per scan, priority processing, and scheduled re-audits. All plans include the full audit engine covering every QA category.
Whether you are a solo developer shipping a side project, a QA engineer at a startup, or a technical lead managing dozens of production sites, NexusBro saves hours of manual review and catches issues human testers miss. Thousands of sites have been audited on the platform, with results improving by an average of 15-25 points after implementing the generated fixes.
