Bubble Security Best Practices

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.

Quick Wins

Review privacy rules for all data types
Move sensitive logic to backend workflows
Test API endpoints without authentication
Verify HTTPS is enforced
Audit editor access permissions

Security Best Practices

#1Configure Privacy Rules for All Data Types

critical

Every 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

critical

Client-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

critical

API endpoints should check authentication and authorization for every request.

Implementation

Add authentication checks to all API workflow triggers

#4Validate All Inputs

high

Never 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

high

Ensure your custom domain has HTTPS enabled and enforced.

Implementation

Configure SSL in Settings → Domain/Email

#6Audit User Permissions Regularly

medium

Review 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

Why it's dangerous:

Data is accessible to logged-in users without restrictions

How to fix:

Configure privacy rules for every data type

Sensitive logic in frontend workflows

Why it's dangerous:

Users can inspect and manipulate client-side workflows

How to fix:

Move to backend/API workflows

Unprotected API endpoints

Why it's dangerous:

Anyone with the URL can call your APIs

How to fix:

Require authentication on all API endpoints

Frequently Asked Questions

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.
