Is Bubble Safe?
Last updated: January 12, 2026
An honest security analysis of Bubble for developers considering it for their projects.
Quick Answer
Safe with caution - privacy rules are hidden but criticalBubble is safe when privacy rules are properly configured, but the visual interface hides critical security settings. Privacy rules are Bubble's equivalent of database RLS - misconfiguration exposes ALL your data. API workflows are public by default. Plugins have varying security quality.
Understanding Bubble Security
When evaluating whether Bubble is safe for your project, it's important to understand the distinction between platform security and application security. Bubble as a platform implements industry-standard security practices for its infrastructure, including encryption, access controls, and regular security audits.
However, the security of applications built with Bubble depends significantly on how developers use the platform. AI-generated code and rapid development workflows can introduce vulnerabilities that exist independently of the platform's underlying security. Research from Stanford University found that AI coding assistants produce vulnerable code approximately 40% of the time when working on security-sensitive tasks.
The most common security issues in Bubble applications stem from misconfigurations, exposed credentials, and missing security controls—problems that developers must address regardless of which platform they use. Understanding these patterns helps you make informed decisions about using Bubble for your specific use case.
Platform Security
Platform security refers to the security measures Bubble implements at the infrastructure level: how they protect their servers, encrypt data in transit and at rest, manage access to their systems, and respond to security incidents. These are controls the platform provider manages on your behalf.
Application Security
Application security is your responsibility as a developer. This includes properly configuring authentication, implementing authorization controls, protecting sensitive data, securing API endpoints, and avoiding common vulnerabilities like exposed credentials or SQL injection. These risks exist regardless of which platform you use.
Common Security Mistakes in Bubble Apps
Based on security scans of thousands of Bubble applications, these are the most frequently encountered vulnerabilities. Understanding these patterns helps you proactively secure your applications.
Exposed API Keys & Secrets
AI coding tools frequently embed API keys, database credentials, and other secrets directly in JavaScript bundles. These credentials become visible to anyone who inspects your application's source code in their browser.
Prevention: Use environment variables and server-side API routes to keep credentials secure.
Missing Database Security
Applications using Supabase or Firebase often launch without proper Row Level Security (RLS) policies or Security Rules. This allows unauthorized users to read, modify, or delete data they shouldn't have access to.
Prevention: Always enable and test RLS policies before deploying to production.
Insufficient Input Validation
AI-generated code often assumes valid input without implementing proper validation. This opens applications to injection attacks, XSS vulnerabilities, and data corruption.
Prevention: Validate all user input on both client and server side.
Missing Security Headers
HTTP security headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security are frequently missing from AI-generated applications, leaving them vulnerable to various attacks.
Prevention: Configure security headers in your hosting platform or application middleware.
Known Security Incidents
Widespread Privacy Rule Misconfigurations
OngoingSecurity 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.
Security Assessment
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
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 Checklist for Bubble
- 1Go to Data → Privacy tab and configure rules for EVERY data type
- 2Make API workflows private: check 'This workflow requires authentication'
- 3Test as logged-out user: can you see data you shouldn't?
- 4Audit plugins: remove unused ones, research security of active ones
- 5Enable 'Prevent data API access' in Settings → General for sensitive types
- 6Use Bubble's security checklist in Settings → General → Security
The Verdict
Bubble can be production-secure, but the visual interface actively hides security settings. Privacy rules are buried in Data → Privacy. API workflows default to public. You must deliberately seek out and configure security - it won't happen by accident. Test your app as a logged-out user to find exposures.

What Security Experts Say
“There's a new kind of coding I call 'vibe coding', where you fully give in to the vibes, embrace exponentials, and forget that the code even exists.”
“It's not really coding - I just see stuff, say stuff, run stuff, and copy paste stuff, and it mostly works.”
Frequently Asked Questions
What are Bubble privacy rules?
Privacy rules are Bubble's equivalent of Row Level Security. They control which users can see/modify which data. Find them in Data → Privacy tab. Without rules, ALL data is accessible to ALL users. This is the #1 source of Bubble security issues.
Are Bubble API workflows secure?
By default, NO. API workflows are public unless you check 'This workflow requires authentication'. Anyone who discovers your API endpoint can call it. Always require authentication and validate user permissions within the workflow.
Are Bubble plugins safe?
Plugin security varies widely. Plugins can access your database and user data. Only use plugins from trusted developers, check reviews, and remove unused plugins. Treat plugins like npm packages - they're third-party code running in your app.
How is Bubble security different from code-based apps?
In code, you explicitly write database queries with security in mind. In Bubble, the visual builder generates queries automatically, making it easy to forget security exists. You must proactively configure privacy rules - they're not enforced by default.
