Wix App Market
Wix App Development for the Wix App Market
We design, build, and ship full applications for the Wix App Market, from OAuth install and billing to dashboards and embedded widgets that run inside merchant sites.
What you walk away with
- A review-ready, multi-tenant Wix app
- Native billing and a usable merchant dashboard
- Per-merchant data isolation that scales
- Clean documented code you own
Overview
Publishing an app on the Wix App Market puts your product in front of millions of businesses, but it is a real software project, not a plugin. A production Wix app needs a secure OAuth installation flow, a backend that handles per-merchant data and tokens, a dashboard your users manage settings from, billing through the Wix billing system, webhooks for install and uninstall events, and embedded elements that render inside the merchant site. Each of those is a place where a weak build leaks data or fails review.
Dude Lemon builds Wix apps the way we build any multi-tenant SaaS product, because that is what a marketplace app is. Every merchant is a tenant with isolated data and credentials. We design the token storage, the data boundaries, and the install lifecycle first, then build the features on top. That foundation is what keeps the app stable as you grow from ten installs to ten thousand.
We have shipped apps and integrations in the Wix ecosystem and run our own products on it, so we know the review expectations, the dashboard patterns, and the gaps in the documentation. We can take you from idea to a submitted, review-ready app, or rescue an app that stalled because the original build could not scale.
Whether you are a startup launching a new marketplace product or an established company extending into Wix, we handle the engineering end to end and leave you with clean, documented, ownable code.
A Wix App Market app is a multi-tenant SaaS product. Treat per-merchant data isolation and the install lifecycle as the foundation, and everything else gets easier.
Capabilities
What a complete Wix app includes
A secure installation and authorization flow with correct scopes, token exchange, and refresh handling per merchant.
Isolated per-merchant data and credentials, built on the same patterns we use for production SaaS platforms.
A settings and management interface where users configure your app, view data, and manage their plan.
Paid plans, trials, and upgrades wired into the Wix billing system so revenue collection is native and reliable.
Install, uninstall, and plan-change webhooks handled cleanly so your records always match reality.
Elements that render inside the merchant site, performant and styled to fit without breaking their theme.
Why Dude Lemon
Why teams choose us for Wix app development
We build Wix apps as multi-tenant products because we run our own products on the platform. We know where the documentation is thin, what the review team expects, and how token handling and per-merchant isolation behave at scale. That experience turns a risky first launch into a predictable one.
You also get an ownable asset. We leave you with clean, documented code, a clear data model, and a team that understands the lifecycle, so you are not locked to us. Whether you want us to keep building or hand off entirely, the app is yours to grow.
What separates a shipped Wix app from a stalled one
Many Wix apps stall after the first prototype because the foundation cannot carry real usage. Token handling was an afterthought, merchant data was not properly isolated, and the install and uninstall lifecycle was never handled, so records drift out of sync the moment the app has more than a handful of users. Fixing this after launch means rewriting the core while customers are already on it.
We avoid that by building the foundation first and treating every merchant as an isolated tenant from day one. The install flow, token storage, and data model are designed before any feature, because they are the hardest things to change later. By the time we build the dashboard and the paid features, they sit on a base that scales, which is why our apps move through review and into growth without a painful rebuild in between.
How we work
A clear path from idea to production
We define what the app does, the plans you will sell, and the data it needs, then translate that into a technical scope and review-readiness checklist.
We build the install flow, token handling, and multi-tenant data model before features, because retrofitting tenant isolation later is expensive and risky.
We build the merchant dashboard and core features in stages, testing each against a real Wix development site as we go.
We wire in billing, handle the lifecycle webhooks, and walk through the App Market review requirements so submission is not a surprise.
We support submission, fix anything review surfaces, and continue feature work and monitoring on a retainer if you want it.

Wix App Development FAQ
Frequently asked questions
Can you take my Wix app from idea to published?
Yes. We handle the full path: product scoping, the OAuth install flow, multi-tenant backend, dashboard, billing, embedded widgets, and the App Market review requirements. You end up with a submitted, review-ready app and documented code you own.
How is a Wix app different from a Velo site customization?
Velo work extends one specific Wix site. A Wix App Market app is a standalone multi-tenant product that any merchant can install. It needs OAuth, per-merchant data isolation, billing, and lifecycle webhooks, which makes it a full SaaS build.
Do you handle Wix billing and paid plans?
Yes. We integrate the Wix billing system so you can sell plans, offer trials, and handle upgrades natively. We also handle the webhooks that keep your records in agreement with the merchant plan state.
Can you fix or scale an existing Wix app?
Yes. We audit the current code, identify why it is failing or hard to scale, and improve the architecture incrementally. We only recommend a rebuild when the existing foundation genuinely cannot support your requirements.
Will the app pass Wix App Market review?
We build against the review requirements from the start and walk through the checklist before submission, so review is predictable. If review surfaces an issue, we fix it as part of the launch.
How long does it take to ship a Wix app?
A focused MVP is often six to ten weeks. A full product with billing and a complete dashboard typically runs longer, delivered in stages. We give you a realistic timeline after scoping.
