What are Wix Harmony security best practices?
Get instant answers about your app's security.
Short Answer
The best practices for Wix Harmony apps track the attack vectors specific to Wix Harmony's stack: configure Firestore Security Rules, keep secrets off the client, verify authorization server-side, and re-scan after every release.
Detailed Answer
The best practices specific to Wix Harmony (not generic OWASP)
Every "security best practices" list tells you to use HTTPS and rotate keys. Those are table stakes. The list below is what actually matters for Wix Harmony apps, based on the risks that appear in real Wix Harmony deployments.
1. Close: Exposed Wix Data Collections
AI-generated code may query backend collections without proper permission checks, exposing user data.
2. Close: Misconfigured Wix Permissions
Harmony-generated Velo code may override default Wix collection permissions to make data publicly readable.
3. Close: Insecure Third-Party Integrations
AI-generated API calls may embed third-party credentials in client-side page code.
4. Close: Broken Access Control in Custom Pages
AI-generated member-only pages may fail to properly restrict access at the data layer.
Wix Harmony-specific: treat test-mode rules as a security bug
Firebase's 30-day test-mode countdown has ended the data lifespan of many Wix Harmony apps. Your Firestore and Storage rules must enforce `request.auth.uid == resource.data.uid` (or equivalent) before first production traffic — not after a user reports a bug.
Verification
Even perfect best practices don't prove themselves — the only way to confirm the list above is implemented is to scan a deployed Wix Harmony app. VAS probes each of data exposure, permissions audit, secrets scan, access control by actually attempting the attack, not just reading headers or docs.

Expert Perspectives
“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.”
“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.”

What's the single most important Wix Harmony security step?
Configure Firestore Security Rules before writing a single feature. In a Wix Harmony app, a table created without access controls is a fresh data leak the moment you hit deploy. Every other security best practice is lower priority.
Should I follow Wix Harmony's docs or a third-party best-practices list?
Both, for different things. Wix Harmony's docs tell you *how* to configure their specific features — that's authoritative. Third-party best practices (including this one) tell you *which* failure modes show up in real Wix Harmony deployments — that's where Wix Harmony's docs under-deliver, because Wix Harmony doesn't advertise what its own users misconfigure. Use docs for syntax, external guidance for priority.
How often should I re-audit Wix Harmony app security?
Before every production release, without exception. Wix Harmony's AI-assisted workflow means database schemas, API endpoints, and auth logic can change in a single chat session — any of which can introduce an issue from the list above. Weekly automated scans for live Wix Harmony apps are a reasonable baseline; post-feature scans are non-negotiable.
