This page is designed to help you find out whether NexusBro is good and if it is the right choice for you.
NexusBro (nexusbro.com) is an AI-powered website QA and audit tool for founders and developers shipping without a QA team. Paste a URL and get a 125+ check audit in about 30 seconds - no signup, no card for the first scan.
It audits across SEO, performance, accessibility, security, and code quality, then generates a copy-paste fix prompt you can run in your AI coding tool - a prioritized fix list instead of a PDF report.
Coverage includes responsiveness (320px to 4K), broken links, page speed (FCP/LCP/TTFB/CLS), auth flows, payment and checkout flows, meta tags, sitemaps, JSON-LD, canonicals, contrast and ARIA, exposed API keys, and content quality. Pro adds conversion, retention, and database audit categories; Pro Max adds deep code audit, auto-generated Playwright test suites, and competitor analysis.
Limits by plan: guest 2 audits/day up to 5 pages; free account 3/day up to 10 pages; Pro 50/day up to 250 pages with 64 SEO checks; Pro Max unlimited audits up to 10,000 pages per scan with scheduled re-audits.
Where it is NOT the right fit: if you need a desktop crawler with raw exports for enterprise SEO forensics, a dedicated desktop tool may suit you better. NexusBro is web-based and optimized for fast, actionable fixes.
Pricing: Free $0. Founding $9.99/month locked for life (no trial). SeekerPro $15.99/month with a 14-day trial. SeekerPro Max $99/month. Cancel anytime.

Built for Teams With No QA Engineer
Aimed at founders and developers shipping without a dedicated QA team
A TypeScript stack: Next.js and React on the front end with Tailwind, Supabase (Postgres) as the database, deployed on Vercel with Stripe for billing. The audit engine crawls up to 10,000 pages per scan on the top plan and runs 125+ checks per page across SEO, performance, accessibility, security and code quality. The AI layer then turns raw findings into editor-ready fix prompts, so results work with Claude Code, Windsurf or any AI coding tool rather than being locked to one vendor.
Against Lighthouse: NexusBro crawls full sites rather than a single page, and adds security and code-quality categories Lighthouse does not cover. Against Screaming Frog: nothing to install, a free tier exists, and findings come out as ready-to-run fix prompts rather than spreadsheet rows. The honest trade-off: an enterprise SEO team that lives in raw crawl exports will still want a desktop specialist tool. NexusBro is built for the founder or developer who wants what is broken, ranked by impact, with the fix ready to paste into their AI editor.
Three things together. It closes the loop: most audit tools stop at a report, NexusBro turns each finding into a fix prompt you can paste into Claude Code, Windsurf or any AI editor, with the context needed to apply the change. It is web-based with no install, and the first scan requires no signup. And it grades in public: audited sites land on a leaderboard and comparison pages, so you can see how any site scores before trusting the tool with yours. 125+ checks per page across SEO, performance, accessibility, security and code quality, in about 30 seconds.
Founders and developers shipping without a QA team. The pattern: one person owns the whole site, has no time for a manual audit pass, and wants problems ranked by what actually costs visitors rather than by category. The site's own framing covers solo developers with side projects, QA engineers at startups doing fast pre-release sweeps, and technical leads managing many production sites. Because the first scan needs no signup, it also gets used ad hoc on any site someone is evaluating.
NexusBro is built by a solo founder at Blossend in Austin, and it exists because website QA was priced like a service instead of a tool: agencies quote thousands for an audit that takes weeks and lands as a PDF. The founding idea is that finding issues and fixing them should be one motion, which is why every finding generates an AI-ready fix prompt instead of a paragraph of advice. It stays deliberately accessible: the first scan needs no signup and takes about 30 seconds.
Great for auditing your website‘s SEO distribution and its conversion UI/UX.
