Cursor
Is Cursor secure?
Cursor is not a security product, and it is not automatically unsafe. Cursor writes the repo on your machine. Visitors see the host you deployed to. A key in a local .env is invisible here. A key compiled into the deployed JavaScript, or returned at /.env, is not.
The scan does not open the Cursor workspace, the chat, or git history on your laptop.
A useful check is the deployed URL
Paste a URL you own. The scan is passive. It does not log in, brute-force paths, or query a database. Supabase Row Level Security and Firebase security rules are not read. Those stay marked as coming soon.
- Cursor: Exposed API keys
- Cursor: Supabase RLS
- Cursor: Firebase security rules
- Cursor: Missing security headers
- Cursor: Open CORS
- Cursor: Exposed .env files
- Cursor: Auth misconfiguration
- Cursor: Cookie flags
- Cursor: Clickjacking protection
- Cursor: Exposed git metadata
- Cursor: Missing robots.txt
Is Cursor secure?
Cursor is a way to build an app. The security question is about the URL you publish. Cursor writes the repo on your machine. Visitors see the host you deployed to. A key in a local .env is invisible here. A key compiled into the deployed JavaScript, or returned at /.env, is not.
What does a free scan cover?
The public page, up to 10 same-origin scripts, headers, cookies, robots.txt, sitemap.xml, homepage links, and five paths: /.env, /.env.local, /.env.production, /.git/HEAD, and /.git/config.
What will a scan of a Cursor URL miss?
The scan does not open the Cursor workspace, the chat, or git history on your laptop.
Scan a URL you own
The same free check as the homepage. You confirm the app is yours before it runs.
