Is Framer Safe?
Last updated: January 12, 2026
An honest security analysis of Framer for developers considering it for their projects.
Quick Answer
Safe - limited attack surface, review code componentsFramer is safe for marketing sites and portfolios - similar to Webflow but with React-based code components. The attack surface is limited (no backend), but code components can introduce vulnerabilities if you write insecure React code. Built-in authentication uses third-party providers securely.
Understanding Framer Security
When evaluating whether Framer is safe for your project, it's important to understand the distinction between platform security and application security. Framer 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 Framer 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 Framer 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 Framer for your specific use case.
Platform Security
Platform security refers to the security measures Framer 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 Framer Apps
Based on security scans of thousands of Framer 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.
Security Assessment
Security Strengths
- Static site generation = no server-side attack vectors
- Automatic HTTPS on Framer's CDN
- Code components are sandboxed React - can't access file system
- Authentication integrates with secure OAuth providers
- CMS data is read-only on published site
Security Concerns
- Code components: custom React code can have XSS if using dangerouslySetInnerHTML
- Third-party scripts added via custom code run with full page access
- CMS content is public unless using Framer's paid gating features
- No server-side validation - all logic is client-side
- Analytics and tracking scripts are trust decisions
Security Checklist for Framer
- 1Review code components for dangerouslySetInnerHTML or eval() usage
- 2Use Framer's built-in integrations instead of custom script embeds when possible
- 3For gated content: use Framer's password/member features, not client-side JS
- 4Audit third-party scripts in Site Settings → Custom Code
- 5Don't store sensitive data in CMS - it's readable in page source
- 6Test authentication flows with incognito mode to verify access control
The Verdict
Framer is as secure as Webflow with added React component flexibility. The lack of backend limits attack surface. Main risks: custom code components (React vulnerabilities) and third-party scripts. Framer's authentication features use secure OAuth - safer than building your own. Great for marketing sites, portfolios, and landing pages.

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
How is Framer different from Webflow security-wise?
Both are static/CMS site builders with similar security profiles. Framer uses React components (can write custom code); Webflow uses visual-only building. Framer's code components add flexibility but also potential for React-specific vulnerabilities like XSS via dangerouslySetInnerHTML.
Are Framer code components safe?
Code components run in a sandboxed React environment - they can't access your file system or make unauthorized requests. However, you can write insecure React code (XSS via dangerouslySetInnerHTML). Review any code components you add, especially from third parties.
Is Framer's built-in authentication secure?
Yes. Framer's authentication uses OAuth providers (Google, etc.) for the actual auth flow. Framer handles session management. This is more secure than building your own auth. Use it for member-only pages instead of client-side JavaScript gating.
Can Framer CMS content be protected?
By default, CMS content is public (visible in page source). Use Framer's password protection or membership features to gate content. Don't use client-side JavaScript to hide content - it can be bypassed by viewing source. Server-side gating requires Framer's built-in features.
