QA result

Fix before launch

Initial HTML, rendered-only content, crawlable links, routes, lazy content, and resource access need review.

Core workflow

Paste initial and rendered samples. Get a JavaScript rendering QA brief.

This MVP analyzes pasted samples in your browser. It does not fetch pages, crawl a site, emulate Googlebot, run Search Console, PageSpeed, Lighthouse, or store snippets remotely.

Paste only public-safe or anonymized samples. Output is QA guidance and does not guarantee crawling, rendering, indexing, ranking, or Search Console outcomes.

Why this exists

JavaScript SEO bugs often live between source HTML and rendered HTML.

Review initial HTML

Flag empty app shells, missing source title, missing source meta description, and weak fallback signals.

Catch rendered-only risk

Compare critical content, headings, links, route patterns, lazy content, and user-action dependencies.

Copy the owner handoff

Turn findings into a clear SSR, pre-render, fallback, crawlable href, unblock, or owner decision prompt.

Pricing hypothesis

Reserve early access before billing is connected.

Pricing is tested through demo requests and purchase intent while payments are unavailable.

FAQ

JavaScript rendering constraints are explicit.

Does it fetch or crawl my site?

No. This MVP only analyzes pasted initial HTML, rendered HTML, notes, and snippets.

Does it emulate Googlebot?

No. It does not emulate Googlebot, run a crawler, use Search Console, or call external APIs.

Does it replace Search Console or rendered crawlers?

No. Those remain necessary. This is a fast prelaunch sample review and owner handoff tool.

Can I paste private client snippets?

The app is browser-local, but you should still paste only public-safe or anonymized samples.
