Zestify – Restaurant SaaS – Next.js Script

Zestify – Multi-Tenant Restaurant SaaS Starter

Skip 6 months of development. Ship a production-ready Restaurant SaaS today.

Zestify is a production-ready multi-tenant restaurant SaaS starter built for developers, SaaS founders, and agencies. It includes a Node.js REST API, a React and Vite admin dashboard, and a Next.js customer-facing application, all written in TypeScript. Use it as the foundation for your own restaurant ordering, management, and SaaS platform instead of building everything from scratch.

Note: Demo mode is read-only.

What Is Included

The download contains three separate, fully wired applications plus documentation for each one.

• Zestify API (api/) – Node.js and Express.js REST API. Handles authentication, multi-tenancy, orders, reservations, payments, OTP email flows, and all business logic. Everything else depends on this running first.
• Admin Dashboard (admin-dashboard/) – React and Vite management interface for restaurant owners and staff. Covers tenant management, menu and product management, orders, reservations, blog, gallery, coupons, customer management, and settings.
• Client App (client-app/) – Next.js public-facing restaurant website. Customers browse the menu, add items to cart, checkout with Stripe or PayPal, make reservations, read blog posts, and manage their account.

A Postman collection is included in the root of the download to test every API endpoint immediately after setup.

Core Architecture – True Multi-Tenancy

The central feature of Zestify is its true multi-tenant architecture. One installation of the platform can serve unlimited restaurants simultaneously. Each tenant gets completely isolated data, its own admin access, and its own branded client app, all managed from a single codebase and a single super admin account.

• Data Isolation – Each restaurant tenant’s data is fully separated. No cross-contamination between tenants at any level.
• Role-Based Access Control – Super admin, tenant admin, and customer roles each with appropriate permission sets.
• Unlimited Tenants – Add as many restaurants as needed without performance loss or code changes.
• Centralised Control – Manage all restaurants from one super admin account with full visibility across tenants.
• Production-Ready Architecture – Architecture decisions made for real-world scale from day one.
