Secure your Bubble.io application with these essential practices. From privacy rules to API security.
Verify your app follows these best practices automatically.
Bubble provides security features, but they require proper configuration. These practices help you build secure no-code applications.
Every data type needs privacy rules. Without them, data is potentially accessible to all users.
Set up privacy rules in Data → Privacy for each data type
Client-side workflows can be inspected and manipulated. Use backend workflows for sensitive logic.
Move payment, auth, and data-modifying logic to backend workflows
API endpoints should check authentication and authorization for every request.
Add authentication checks to all API workflow triggers
Never trust client-side input. Validate data in privacy rules and workflows.
Add constraints and validation in workflows before processing data
Ensure your custom domain has HTTPS enabled and enforced.
Configure SSL in Settings → Domain/Email
Review who has editor access to your app and what data they can see.
Review Settings → Collaboration and data logs periodically
Data is accessible to logged-in users without restrictions
Configure privacy rules for every data type
Users can inspect and manipulate client-side workflows
Move to backend/API workflows
Anyone with the URL can call your APIs
Require authentication on all API endpoints
Following best practices is the first step. Verify your app is actually secure with a comprehensive security scan.
Scan Your App FreeYes, Bubble can be used for production apps with proper security configuration. The key is configuring privacy rules, using backend workflows, and protecting API endpoints.
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.
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.
