The final pass before you ship.

Frontend Auditor is built for developers, marketers, SEO specialists and product teams who want to catch common issues before a website, landing page or widget goes live. It's not a replacement for Lighthouse or PageSpeed Insights — it runs earlier in the loop, against the raw code you're about to publish.

Paste your HTML, CSS or JavaScript, run the audit, and get a focused report covering SEO, accessibility, performance readiness and best practices. Every issue ships with a clear explanation, the impact, and a before/after code example so the report is educational, not just diagnostic.

No accounts. No onboarding. No workspaces. Reports can be shared as a public link that expires after 30 days.
