Builder
Cursor
Cursor edits your repository. Nothing ships until you ship it, and that is the difference.
What the builder handles for you
Edits across many files at once.
Repository rules it will follow if you write them.
A diff you can read before you accept it.
What it does not
It does not deploy, so hosting, headers and certificates are yours.
It does not check that an imported package exists.
It does not know your production data from your test data.
Incidents involving it
The Tenzai study of five AI coding tools found 69 vulnerabilities across 15 apps.
A slopsquatting campaign put 126 malicious npm packages behind names AI tools invent.
The fix prompt dialect
Cursor prompts say apply it across the project and show me a diff. They keep the change in one place and end with a verification step.
Stack checklists that apply
Cursor, Next.js, Supabase, Vercel.
