Webflow vs Framer Security
Webflow and Framer are visual website builders that have evolved toward more capable application features. Both allow custom code, but their security models differ in how they handle dynamic content, authentication, and third-party integrations. Understanding these differences matters for building secure marketing sites and web applications.

The Verdict
Webflow offers more built-in security features including native authentication (Memberships) and PCI-compliant e-commerce. Framer requires third-party integrations for these features, which adds complexity and potential security gaps. For simple marketing sites, both are comparable. For sites with user accounts or payments, Webflow's integrated approach is more secure.
For marketing sites without user data: either platform works, focus on securing custom code embeds. For sites with memberships: Webflow's native Memberships is more secure than third-party integrations. For e-commerce: Webflow's PCI-compliant system is safer than bolting on third-party solutions to Framer.

“Vibe coding your way to a production codebase is clearly risky. Most of the work we do as software engineers involves evolving existing systems, where the quality and understandability of the underlying code is crucial.”

Start Security ScanFrequently Asked Questions
Are custom code embeds a security risk?
Yes, on both platforms. Embedding third-party scripts or custom code can introduce XSS vulnerabilities, data leakage, or malicious behavior. Only embed code from trusted sources, review what scripts do before adding them, and avoid embedding scripts that load additional unknown code. CSP headers help but aren't always configurable.
Which platform is safer for handling user authentication?
Webflow's native Memberships feature is safer because it's built-in and maintained by Webflow. On Framer, you'd integrate third-party auth services, which adds complexity and potential security gaps in the integration layer. Built-in solutions typically have fewer security issues than integrations.
How do CMS APIs affect security?
Both platforms expose APIs for CMS content. Ensure API keys are kept secret, use them server-side only, and implement appropriate rate limiting. Neither platform's API should expose sensitive data if you configure CMS access controls properly. Review what fields are exposed through the API.
Should I handle payments through these platforms?
For payments on Webflow, use their native e-commerce which handles PCI compliance. For Framer, you'll integrate Stripe or similar - ensure the integration follows security best practices and never handles card data directly. Third-party payment integrations can be secure but require careful implementation.
