Lovable migrated its own website (lovable.dev) from Next.js on Vercel to TanStack Start, hosting it on Lovable's own platform alongside its users' apps. The migration took six months and involved running both frameworks in parallel, routing requests per-user and per-route to minimize hard navigations, and organizing routes into migration groups to maintain user experience.

## Evidence

Verbatim from https://lovable.dev/blog/how-we-migrated-lovable-dev-away-from-nextjs:

> We migrated lovable.dev to TanStack Start to serve it the same way—now it's just one of the possible destinations among 60M+ of our users' apps. There are fewer than 200 lines of code unique to the lovable.dev serving path (mainly handling a different release metadata format and a different observability setup).
