Replit Agent and Replit Deployments are great at getting you to a live URL. They're not great at telling you that the favicon is Replit's, the headers are missing, and your DB is exposed.
Replit's Deployments make it trivial to ship. The catch: there's no opinionated checklist of what production-grade actually means. PageLens turns that checklist into a visible launch-readiness report with severity ratings.
Each pattern is written from public-page audit evidence and ships with a one-line fix suggestion in the report.
Fast generated prototypes can blur server and browser boundaries. We check whether database credentials or sensitive API details are visible from the public client bundle.
If you bought a domain but kept the *.replit.app live, Google indexes both and splits your authority. Canonical tag fixes it in one line.
Default Replit favicons are easy to miss in production browser tabs. The fix is small, but the trust signal is visible.
Replit Deployments need application-level header decisions for CSP, HSTS and frame protection. We grade the public response and explain the missing controls.
Replit's free/hobby tier cold-starts on every visit after inactivity. We measure and report TTFB so you know if your tier is the problem.
Replit Agent tends to skip <head> altogether. Search and social previews look terrible.
Generated UIs often use red/green colour alone to indicate status. Fails WCAG 1.4.1 (use of colour).
Check these before you share your link. The full PageLens AI audit catches everything else.
This covers the basics. A full PageLens AI scan checks hundreds of rules across 10 categories — including the ones that are hard to spot manually.
After your scan, download the Markdown report and use this prompt with your AI builder to fix everything automatically.

Yes. Most issues we surface (headers, SEO, accessibility, content) are independent of where you're hosted. We'll also flag the canonical-tag issue specific to using a Replit subdomain alongside a custom domain.
We just hit your URL like a real visitor. If your Repl is sleeping when we arrive, we'll surface that as a finding (cold-start latency hurts both SEO and conversion).
