Telling them apart
Lovable
How to spot it: Open the page source (Ctrl+U) and search for gpteng.co. Lovable projects load their editor script from that host.
What usually goes wrong: API keys left in the JavaScript bundle. Lovable projects often talk to Supabase or another backend straight from the browser, so the key ends up in a file anyone can download. If that key is a service role key rather than an anonymous one, the whole database is readable. Our scanner downloads up to three bundles and reports any key it finds, redacted.
How to spot it: Search the page source for a generator meta tag naming Durable.
What usually goes wrong: Copy that says nothing specific. Generated text is grammatical and generic. It rarely names the town you serve, what you charge, or what makes you different, which is exactly what a local customer is looking for.
Can you tell whether a site was built with Lovable or Durable?
Usually, yes. Each leaves its own traces: Lovable on *.lovable.app and in its scripts, Durable on durable.co and in its own markers. Paste the URL in the scanner above and it names the builder with the evidence it found.
Which is better for SEO, Lovable or Durable?
Neither decides it alone. In our sample the biggest SEO gaps were a missing main heading and a missing meta description, both fixable on either platform. Compare the rows above, then scan your own site to see which of them apply to it.
Is a Lovable site worse than a hand-built one?
Not by being AI-built. The problems we see most are defaults nobody changed: titles, badges, blocked zoom, and database keys used without access rules. Each is a short fix once you know it is there.
