Building software should be accessible to everyone. With Lovable, anyone can create apps by simply describing what they want - no coding required. Just tell Lovable your idea and watch it come to life.
But when you're building something that will handle sensitive data, security becomes essential. If your app is not secure, anyone could access that sensitive data.
That's why we've added security features to help prevent and catch common issues, so you can build with more confidence.
Security Scan
Before you publish your app with Lovable, we automatically scan it for security issues.
Lovable apps connected to Supabase use a security model called Row Level Security (RLS) — a powerful access control system that works well with AI, since AI is great at SQL.
However, if RLS policies aren’t created — or if they’re set up with overly broad permissions — data from your Supabase database could be exposed.
To help prevent this, we’ve integrated Supabase’s Security Advisor directly into Lovable. It highlights potential security issues in your app so you can fix them before publishing.
Security Reviewer
The Security Scan catches many issues, but sometimes incorrect database security setups slip through. There are also other types of vulnerabilities unrelated to RLS—like accidentally hardcoding API secrets into your app or leaving Supabase Edge Function endpoints unprotected. That’s where our Security Reviewer comes in.
We built an AI-powered security reviewer that analyzes your entire app for potential vulnerabilities and suggests exactly how to fix them. It catches database security problems plus other issues like code injection, cross-site scripting, and authentication vulnerabilities.
The security reviewer understands how your specific app should work and identifies where security might be missing.
While we can’t guarantee your app will be 100% secure, this feature should catch the most common problems.
Automatic API Key Protection
Previously, people would sometimes ask Lovable to hardcode API secrets into their app, which posed a major security risk as those secrets could be easily leaked. We now block around 1200 private API keys from being directly inserted in code per day.
All API secrets should be stored as secrets in Supabase. You can do this either by clicking the “Add Key” button that Lovable displays in the chat when asked to use an API, or by navigating to “Edge Functions” in Supabase and adding the secret manually.
Conclusion
Security is critically important when building apps that will be used by others, and at Lovable, we focus heavily on helping users create more secure apps.
We’ve recently introduced features like Security Scan, Security Reviewer, and Automatic API Key Protection to make it easier for anyone to build secure apps with Lovable.
