I would not use Cursor to ship a Next.js site faster if faster means skipping review. Cursor accelerates boilerplate, refactors, and copy tweaks. It does not know your production constraints.
Sensible flow
Scaffold routes and components with clear prompts.
Run `npm run build` often.
Check server versus client component boundaries.
Test auth and env vars on a preview deploy.
Prompts that work
"Add a marketing page at `/pricing` using existing Tailwind tokens. Server component. No new dependencies."
Watch for
Hallucinated imports.
Wrong app router patterns.
Leaked secrets in client bundles.
Speed is real when diffs stay small and builds stay green. Otherwise you just fail in production sooner.
