Security for your Bolt app
Bolt.new spins up a full-stack app in the browser and deploys it in one click, but that speed hides security decisions: keys you paste into the chat that end up in the frontend, zero headers, and a SPA that AI cannot see. Scan your app and know for sure in 30 seconds.
Typical risks in Bolt
Keys pasted in the chat that end up in the frontend
To "connect" a service you paste the key into Bolt, and it often wires it into client code. Everything that reaches the browser is public: that key is on display.
Deploy without security headers
Bolt's deploy serves your app over HTTPS but without CSP, HSTS or X-Frame-Options. These headers are not there by default and must be added at the host.
SPA invisible to search engines and AI
Bolt generates SPAs whose content only appears after JavaScript runs. AI crawlers and some search engines see a near-empty page and cannot index or cite you.
