As answered by people managing Cursor and ValidateHTML.
ValidateHTML's answer:
12 validation tools in one place with an instant quality score from 0 to 100. No signup, no limits, completely free. Paste code or enter a URL and get results in seconds.
ValidateHTML's answer:
Instead of opening 5 different tabs (W3C for HTML, JSONLint for JSON, separate tools for meta tags, Open Graph, accessibility), ValidateHTML combines everything in one interface. Plus you get a quality score that tells you exactly where you stand.
ValidateHTML's answer:
Web developers, frontend engineers, and SEO specialists who need to validate code quality before deploying. Also useful for freelancers and agencies managing multiple client sites.
ValidateHTML's answer:
I was tired of opening 5 or 6 different tabs every time I needed to validate my code before deploying. W3C for HTML, JSONLint for JSON, random sites for meta tags. So I built one tool that does everything, with a quality score to instantly know where you stand.
ValidateHTML's answer:
Next.js, React, TypeScript, Tailwind CSS, deployed on Vercel.
ValidateHTML's answer:
Independent web developers, Freelance frontend engineers and Small web agencies.
