Is Webflow Safe?

Last updated: January 12, 2026

An honest security analysis of Webflow for developers considering it for their projects.

Quick Answer

Safe - limited attack surface as visual builder

Webflow is safe for marketing sites and CMS content - it's a visual website builder, not a full application platform. Security risks come from custom code embeds (potential XSS), CMS reference field visibility, and third-party integrations. No backend logic means limited attack surface.

Security Assessment

Security Strengths

  • Managed AWS hosting with automatic SSL and CDN
  • No server-side code = no SQL injection, no backend vulnerabilities
  • CMS data is read-only on published site (edits only in designer)
  • SOC 2 Type II certified with enterprise options
  • Automatic security updates - no patching required

Security Concerns

  • Custom code embeds can introduce XSS if pasting untrusted code
  • CMS reference fields can expose linked content if visibility not configured
  • Third-party embeds (scripts, iframes) inherit their security issues
  • Form submissions sent via email or webhooks - no built-in validation
  • Client-side only - can't implement server-side security logic

Security Checklist for Webflow

  • 1
    Audit Page Settings → Custom Code for any untrusted scripts
  • 2
    Configure CMS Collection visibility: Collection Settings → Access
  • 3
    Enable reCAPTCHA or honeypot on forms to prevent spam
  • 4
    Use Webflow's built-in form handling instead of third-party services when possible
  • 5
    Review third-party embeds for security - each is a potential vector
  • 6
    Add security headers via custom code or Cloudflare proxy

The Verdict

Webflow is inherently secure for its purpose: visual website building. The limited attack surface (no backend, read-only CMS) is a security advantage. Risks come from what you add: custom code embeds, third-party scripts, and misconfigured CMS visibility. Not suitable for apps requiring server-side logic or user authentication.

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

Is Webflow secure for business websites?

Yes. Webflow is SOC 2 Type II certified and hosts on AWS with automatic SSL. The read-only nature of published sites (no server-side code) eliminates many attack vectors. Enterprises use Webflow for marketing sites - just be careful with custom code embeds.

Can Webflow sites be hacked?

The Webflow platform itself is secure. Risks come from what you add: malicious custom code embeds, vulnerable third-party scripts, or exposed CMS content. There's no backend to exploit, no database injection possible. The attack surface is limited by design.

Are Webflow forms secure?

Webflow forms use HTTPS and can integrate with reCAPTCHA. However, Webflow can't validate data server-side - it's client-only. For sensitive data, use integrations like Zapier to route to secure services. Don't collect payment info directly in Webflow forms.

How is Webflow different from Bubble security-wise?

Webflow is a website builder (static/CMS content); Bubble is an app builder (dynamic data, user auth, logic). Webflow has less attack surface but less functionality. Bubble needs careful privacy rules; Webflow needs careful custom code review. Different tools for different purposes.
