Security Best Practices
#1Configure Privacy Rules for All Data Types
criticalEvery data type needs privacy rules. Without them, data is potentially accessible to all users.
Implementation
Set up privacy rules in Data → Privacy for each data type
#2Use Server-Side Workflows for Sensitive Operations
criticalClient-side workflows can be inspected and manipulated. Use backend workflows for sensitive logic.
Implementation
Move payment, auth, and data-modifying logic to backend workflows
#3Protect API Endpoints
criticalAPI endpoints should check authentication and authorization for every request.
Implementation
Add authentication checks to all API workflow triggers
#4Validate All Inputs
highNever trust client-side input. Validate data in privacy rules and workflows.
Implementation
Add constraints and validation in workflows before processing data
#5Use HTTPS for Custom Domains
highEnsure your custom domain has HTTPS enabled and enforced.
Implementation
Configure SSL in Settings → Domain/Email
#6Audit User Permissions Regularly
mediumReview who has editor access to your app and what data they can see.
Implementation
Review Settings → Collaboration and data logs periodically
Common Mistakes to Avoid
Missing privacy rules
Data is accessible to logged-in users without restrictions
Configure privacy rules for every data type
Sensitive logic in frontend workflows
Users can inspect and manipulate client-side workflows
Move to backend/API workflows
Unprotected API endpoints
Anyone with the URL can call your APIs
Require authentication on all API endpoints
Verify Your Bubble App Security
Following best practices is the first step. Verify your app is actually secure with a comprehensive security scan.

Is Bubble secure for production apps?
Yes, Bubble can be used for production apps with proper security configuration. The key is configuring privacy rules, using backend workflows, and protecting API endpoints.
What are privacy rules?
Privacy rules control who can see, create, or modify each data type. They're evaluated server-side and are the primary security mechanism in Bubble.
Can users access my workflows?
Users can see client-side workflow structure (not content) in browser dev tools. That's why sensitive logic should be in backend workflows which are server-side only.
