Zendo is a complete, production-ready customer messaging platform you can run as your own SaaS business. Your customers sign up for their own workspaces, connect their channels, and handle every conversation from one shared inbox — while you, the platform owner, control plans, branding, limits, and billing. It ships with a Laravel 12 + React 19 (Inertia) web application and a native Flutter (iOS + Android) staff app.
