How to Secure Your Bubble App
Last updated: January 12, 2026
Bubble provides security features, but they need proper configuration. This guide covers securing your Bubble.io no-code application.
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.

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.
