This comparison is judged on one concrete job: taking a polished reference design, mockup, or live URL and turning it into a working product rather than a convincing screenshot. Lovable and Same.new diverge sharply here because Same.new is strongest when the task is visual replication, while Lovable is built around turning UI ideas into a React app with Supabase-backed data, auth, and production plumbing.
That job exposes the failure modes that actually matter. A tool can look brilliant on first render and still collapse once forms, permissions, database reads, and revision requests arrive; the real question is not who copies pixels faster, but which tool leaves less fragile code and fewer expensive repair loops when the design has to start behaving like software.
