Is Bolt safe? How to secure your Bolt app
Bolt (bolt.new) generates full-stack apps in the browser. Speed is the point — security review is on you.
Bolt is safe to build with, but like other AI builders it commonly produces apps with exposed keys, missing access control and unprotected backends. Run a security pass before launch.
Bolt (bolt.new) is a legitimate in-browser AI app builder, and it is safe to build with. The catch is the same as every AI builder: the apps it generates commonly ship with API keys baked into the client bundle, missing authorization checks, and permissive CORS. Speed is the product; the security review is on you. Run a scan and tighten access control before you launch a Bolt app to real users.

The most common Bolt security risks
API keys in the client bundle
Third-party and backend keys can be baked into the frontend where they're trivially extracted.
Missing authorization checks
Endpoints and pages may not verify that the requester is allowed to access the data.
Permissive CORS
Wide-open CORS can let untrusted origins call your backend directly.
