Security Analysis

Is Bolt.new Safe?

An honest security analysis of Bolt.new for developers considering it for their projects.

Quick Answer

Safe with caution - review code before production

Bolt.new is a legitimate tool by StackBlitz and is safe to use for development. However, apps built with it need security review before production. Common issues include exposed API keys and missing database security.

Security Assessment

Security Strengths

Built by StackBlitz, an established company
Runs code in secure WebContainer environment
Integrates with reputable backends (Supabase, Firebase)
Generates modern frameworks with security features available

Security Concerns

AI may hardcode API keys directly in source code
Database tables often created without security rules
Security headers rarely configured by default
Source maps may expose source code in production
Authentication implementations may have weaknesses

Security Checklist for Bolt.new

1
Search code for hardcoded API keys and move to environment variables
2
Configure Supabase RLS or Firebase Security Rules
3
Add security headers in your hosting configuration
4
Disable source maps in production builds
5
Test authentication for weak password acceptance
6
Run a security scan to find issues AI missed

The Verdict

Bolt.new is legitimate and great for rapid prototyping. Before deploying to production, you must review the generated code for security issues. The speed of AI code generation often means security configurations are skipped.

What Security Experts Say

“There's a new kind of coding I call 'vibe coding', where you fully give in to the vibes, embrace exponentials, and forget that the code even exists.”
Andrej Karpathy — Former Tesla AI Director, OpenAI Co-founder

“It's not really coding - I just see stuff, say stuff, run stuff, and copy paste stuff, and it mostly works.”
