Lovable makes shipping a site effortless — but effortless isn't the same as launch-ready. Scan yours in seconds to find what's still broken.
React single-page app, rendered in the browser. Lovable ships a Vite + React single-page app: one index.html, and every route drawn by JavaScript after the page loads. Google does execute JavaScript, but it does so in a second pass that can lag the first crawl by days — and it is the first crawl that decides whether your page is worth queueing at all.
Lovable is unusually good at getting something real on screen fast. The gap it leaves is everything that happens outside the browser window: what a crawler receives, what a phone renders, and what your Supabase project will hand to anyone who asks it directly.
Most Lovable sites we scan are not broken in the obvious sense. They look finished. They fail on the things you cannot see from inside the editor preview — an empty HTML shell served to Google, a meta description that is still the Vite default, a database table that was never given a Row Level Security policy.
The checks below are the ones that actually come back positive on Lovable builds, in rough order of how often we see them.
These are the launch-blockers we actually find on Lovable builds, roughly in order of how often they come back positive — each with the specific change that clears it.
Your content is assembled in the browser, so the HTML that leaves the server is a near-empty <div id="root">. Ask for your own page with JavaScript disabled and you will usually see exactly what a first-pass crawler sees: nothing.
The fix: Add prerendering or SSR for your public marketing routes. If the app is genuinely an app, that's fine — but the pages you want found in search need real HTML at request time.
A single-page app has one index.html, so unless something rewrites the head per route, /pricing and /about ship the same <title> as the home page. Google treats that as a strong duplicate signal and usually indexes one of them.
The fix: Set a distinct title and meta description per route (react-helmet-async, or your framework's head API) and confirm it in View Source, not DevTools — DevTools shows the post-JavaScript DOM.
The anon key in your frontend is supposed to be public — that is not the bug. The bug is a table with Row Level Security switched off behind it, which makes every row in that table readable by anyone who copies the key out of your bundle. A service_role key pasted into frontend code is the rarer, worse version.
The fix: Turn RLS on for every table and write an explicit policy per table. Then search your built bundle for "service_role" — if it appears, rotate that key immediately.
Lovable does not generate either for you. Without a sitemap, Google discovers your inner routes only by following links — and in a client-rendered app there often aren't any real <a href> links to follow.
The fix: Add a static sitemap.xml listing every public route, submit it in Search Console, and make sure your nav uses real anchors rather than onClick handlers.
The Lovable preview pane is a desktop browser at a narrow width. It does not reproduce iOS Safari's viewport behaviour, dynamic toolbars, or tap-target sizing, so horizontal overflow and unreachable buttons survive to production.
The fix: We render your live URL in a real mobile viewport and report the elements that overflow, the tap targets under 44px, and the text that clips.

Unlock the report for $12 (₹299 in India) — we scan every page and write the fixes for Lovable.
Paste the fixes into Lovable, say "repair it", and re-scan to confirm. Done.
The short version, if you would rather do it by hand. Everything here is something you can verify yourself in a few minutes.
Almost always one of three things: the page is client-rendered so the first crawl saw an empty shell, there is no sitemap so nothing was discovered, or every route shares one title so Google indexed a single page and dropped the rest. A scan tells you which of the three is yours.
The anon key is designed to be public, so by itself, no. It becomes a problem the moment a table behind it has Row Level Security switched off — then that key reads every row in the table. We flag tables that respond to an unauthenticated read.
Not automatically — we do not touch your project. We write the repair as a prompt in Lovable's own vocabulary, you paste it into the Lovable chat, and then you re-scan to confirm the fix actually landed.
Yes. We scan what is publicly reachable from outside, exactly as Google and a real visitor would see it. A preview URL behind Lovable's editor session cannot be reached from outside, so there is nothing to check.
The free Launch Score scans your home page and names your top problems, with no signup. Scanning every route and getting the copy-paste Lovable fixes is the paid report, from $12 (₹299 in India).
