Most Secure Vibe Coding Platform
AI code generators make shipping fast, but which ones produce the most secure output? We ranked the top 10 vibe coding platforms on security defaults, secret management, auth configuration, and more.
Why Platform Security Defaults Matter
When you build with a vibe coding platform, you inherit its security posture. The AI generates code based on patterns it learned — and most of those patterns prioritize functionality over security. A platform with strong security defaults gives you a head start. One with weak defaults gives you a liability.
We evaluated each platform across five categories that determine how secure your app will be before you do any manual hardening. The scores reflect what you get out of the box, not what's theoretically possible with extensive configuration.
Security Configuration
Does the platform set up database access controls, CORS policies, and input validation automatically?
Secret Management
How does the platform handle API keys? Are they placed in environment variables or embedded in client code?
Auth & Headers
What authentication is pre-configured, and does deployment include security headers like CSP and HSTS?

Platform-by-Platform Breakdown
1Firebase Studio7.5/10
Leverages Google Cloud infrastructure with built-in Firebase Auth and Security Rules. Strongest auth defaults of any platform, but generated code can still leave Firestore in test mode.
2Cursor7/10
IDE-based approach gives you full control over environment variables and deployment. Security depends heavily on your own setup, but that control is an advantage for security-conscious developers.
3Windsurf6.5/10
Similar IDE model to Cursor with good secret management through environment variables. Code generation occasionally produces hardcoded configuration values that should be externalized.
4Replit6/10
Built-in Secrets tab helps manage API keys, and Replit Auth provides quick authentication setup. However, generated code often references secrets directly and security headers are minimal on Replit-hosted apps.
5Lovable5.5/10
Good Supabase Auth integration out of the box, but frequently generates code with missing RLS policies. API keys sometimes appear in client-side bundles. Convenient but security requires manual verification.
6Bolt.new5/10
Fast prototyping with decent auth scaffolding, but secret management is a weak point. API keys are frequently embedded in client code, and deployed apps lack security headers by default.
7v05/10
Primarily a UI generation tool, so backend security depends entirely on what you pair it with. Clean component output, but no built-in security configuration or auth setup.
8Tempo Labs4.5/10
Visual-first approach produces clean UI code but security configuration is largely left to the developer. Limited auth scaffolding and no built-in secret management tooling.
9Trae4/10
Newer entrant with growing capabilities. Security features and documentation are still maturing. Generated code requires careful review for hardcoded credentials and missing access controls.
10Devin4/10
Autonomous AI agent approach means less developer oversight during code generation. While it can handle complex tasks, security configuration is inconsistent and requires thorough post-generation review.
The Reality: No Platform Is Secure by Default
Even the top-ranked platform scored 7.5 out of 10. The honest truth is that no vibe coding platform produces production-ready secure code by default. Every AI-generated application needs security verification before launch.
The ranking above tells you where you're starting from, not where you'll end up. A developer using the lowest-ranked platform who scans and fixes their app will ship something more secure than a developer using the top-ranked platform who never checks.
This is exactly why we built VAS. Regardless of which platform you use, you need to verify the output. VAS scans your deployed application by URL, detects your platform and framework automatically, and checks for the specific vulnerability patterns that each AI code generator tends to produce.
Frequently Asked Questions
Which vibe coding platform has the best security defaults?
Firebase Studio currently leads our ranking because it leverages Google Cloud's infrastructure, enforces Firebase Auth integration, and has the most mature Security Rules system. However, even Firebase Studio-generated code can leave Firestore databases in test mode or embed configuration values in client-side code. No platform eliminates the need for security scanning.
Do vibe coding platforms handle API keys securely?
Most struggle with this. IDE-based tools like Cursor and Windsurf give you control over environment variables, which means secret management is in your hands. Hosted platforms like Lovable and Bolt.new sometimes embed API keys directly in client-side code because the AI prioritizes making the app functional over keeping credentials secure. Always check your deployed app's JavaScript bundles for exposed secrets after generating code with any AI tool.
Is Cursor more secure than Lovable for building apps?
Cursor gives you more control, which can mean better security if you use that control wisely. Because Cursor operates as an IDE extension, you manage your own environment variables, deployment pipeline, and security configuration. Lovable handles deployment for you, which is more convenient but means you have less visibility into security headers and server configuration. Neither produces secure code by default — the difference is in how much control you have to fix it.
Should I scan my AI-generated app even if the platform claims to be secure?
Yes, always. Platform-level security (DDoS protection, SSL certificates, infrastructure hardening) is different from application-level security (database access controls, secret management, security headers). A platform can have excellent infrastructure security while the AI-generated code running on it has exposed API keys and disabled access controls. VAS tests the application layer — the part that platforms cannot protect for you. Starter Scans start at $5, and a single scan before launch is worth more than any amount of platform marketing about security.
Verify Your Platform's Output
Regardless of which vibe coding platform you use, scan your deployed app before launch. VAS detects your platform automatically and checks for the vulnerabilities each one tends to produce.
