How to Secure Your Bubble App
Last updated: April 20, 2026
Bubble provides security features, but they need proper configuration. This guide covers securing your Bubble.io no-code application.
Why Security Matters for Bubble
Key Security Concerns
- Privacy rules buried in Data → Privacy tab - easy to miss entirely
- API workflows are PUBLIC by default - anyone can call them
- Visual builder hides security settings behind multiple menus
- Third-party plugins have access to your data with varying security
- Database structure visible to anyone who inspects network requests
Security Strengths
- Built-in user authentication with SSO options
- Privacy rules system (like RLS for no-code)
- Hosted on AWS with automatic SSL
- Version control and rollback capabilities
- SOC 2 Type II certified on paid plans
Known Security Incidents
Widespread Privacy Rule Misconfigurations
highOngoing
Security researchers regularly find Bubble apps with missing privacy rules, exposing user data. Unlike code-based apps where you explicitly write queries, Bubble's visual nature makes it easy to forget privacy rules exist.
Step-by-Step Security Guide
1. Configure Privacy Rules
Every data type needs privacy rules. Without them, data may be accessible to any logged-in user.
2. Use Backend Workflows
Move sensitive logic (payments, data modifications) to backend workflows. Client-side workflows can be inspected.
3. Protect API Endpoints
Add authentication checks to all API workflow triggers. Don't expose unauthenticated endpoints.
4. Test Privacy Rules
Log in as different user types and verify each can only access appropriate data.
5. Secure Form Inputs
Validate inputs in workflows. Never trust client-side data validation alone.
6. Audit Plugins
Review installed plugins for security. Only use plugins from trusted developers.
Common Security Mistakes
Avoid these common Bubble security pitfalls:
- Missing privacy rules on data types
- Sensitive logic in client-side workflows
- Unauthenticated API endpoints
- Trusting client-side validation
- Installing untrusted plugins

Ready to Secure Your App?
Security is an ongoing process, not a one-time checklist. After implementing these steps, use vas to verify your Bubble app is secure before launch, and consider regular scans as you add new features.
Frequently Asked Questions
Are Bubble privacy rules secure?
Yes, privacy rules are evaluated server-side and can't be bypassed from the client. The key is configuring them correctly for every data type.
Can users see my workflow logic?
Users can see client-side workflow structure (not all details) in browser dev tools. That's why sensitive operations should use backend workflows which are fully server-side.
