Web QA Playground is a free, browser-based QA workspace for any public website. Enter a URL and it runs deterministic checks across SEO, accessibility, performance, responsive configuration, security headers and broken internal links, then gives you an explainable 0–100 QA score. Every finding is backed by real evidence pulled from the page — never invented — and anything that genuinely can’t be measured in-browser is marked “not available” instead of faked.
Run a full QA sweep in under a minute:
Enter any public website URL and it runs deterministic checks across SEO (title, meta description, canonical, Open Graph, structured data, headings, image alt), accessibility (missing alt text, unlabeled controls, heading order, document language, duplicate IDs, landmarks), performance (TTFB, HTML size, resource counts and types), responsive configuration, security headers, and a same-origin crawl for broken internal links — then gives an explainable 0–100 QA score.
No. The score is fully deterministic. Each category starts at 100 and loses a fixed, documented penalty per failed or warned check by severity; the overall score is a weighted average of the categories that could actually be measured. AI never decides the score, and checks marked "not available" never affect it.
A browser cannot read another origin’s HTML or headers directly. Web QA Playground fetches the public page through a server-side proxy that only reaches public hosts (it blocks private/loopback/cloud-metadata addresses), forwards no cookies or credentials, and returns just the HTML and safe headers. Your browser then analyzes that HTML locally.
Field metrics such as First Contentful Paint, Largest Contentful Paint, Cumulative Layout Shift and long tasks require actually rendering the page in a real browser. That backend is architected but not enabled in this phase, so those metrics are honestly shown as "not available" rather than estimated or faked. TTFB, HTML size and resource composition are measured.
Yes. It only inspects publicly available information, never logs in, never sends any destructive traffic, and forwards no credentials. No API keys are exposed in your browser, and nothing you test is stored on our servers.
The crawler is opt-in and polite: it only follows same-origin links, never re-visits a URL, and stops at a page limit you choose (default 25). It is read-only and does no aggressive or parallel hammering.
