Wix security audits, code reviews, and migrations to modern stacks
Wix is a visual website builder with a JavaScript-like backend (Velo). It's fast for marketing sites; production apps with Velo backend functions need the same rigor as any web app.
Top issues we find auditing Wix apps
Patterns documented in primary-source security research, community forums, and real-world audits. These are the things that ship to production and break in front of users.
Velo backend suppressAuth misuse
Public web modules using wixData.query(..., {suppressAuth: true}) without their own permission checks let any visitor bypass collection ACLs.
API keys in frontend page code
Velo developers paste secrets into frontend $w.onReady handlers that ship to every visitor.
Members/PublicData over-permissioned
Default permissions allow anonymous read of member emails and profile fields.
Slow Core Web Vitals
Heavy framework (~1MB+ JS baseline), render-blocking fonts, and aggressive third-party app loading. LCP routinely exceeds 4 seconds on mobile.
Pages accidentally noindex
When toggled off the navigation, Wix doesn't surface this clearly. Sites lose traffic without anyone noticing.
Form data exposed via Velo backend functions
Backend functions are callable by any client without origin verification.
Predictable file URLs
Uploads to Wix Media often have guessable paths. Private uploads aren't actually private.

Cost & performance gotchas
- Wix's ad-tier injects ads on all free sites.
- Premium plans required to remove ads, get analytics, or use Velo at scale.
- Bandwidth caps on lower-tier plans.

Frequently asked questions
- Are Wix sites secure?
- The platform itself is hardened, but Velo-built sites with custom backend code regularly leak data. Common issues: suppressAuth bypass, API keys in frontend code, over-permissioned Members collections. We audit Velo apps for these patterns.
- How do I export my Wix site?
- You largely can't. There's no content export, no template export, no e-commerce export. Blog posts are limited to a 20-item RSS feed. Migration is a manual rebuild — we typically rebuild in Next.js + Sanity or move to Webflow.
- Can you make my Wix site faster?
- Within limits. We can audit and tune what you control: image sizes, custom code, third-party app loading, font strategy. But Wix's ~1MB baseline framework is a fixed cost, so deep performance gains usually require migrating off Wix.
