New Courier Toasts SDK

We’re excited to release Courier Toasts, a completely rebuilt SDK for delivering real-time in-app toast notifications for Web and React apps. Toasts now share the same message feed as your Inbox, so you get one source of truth, real-time sync, and no duplicate infrastructure. Built with smart defaults like stacking, auto-dismiss timers, and action buttons, they work out-of-the-box while giving you full control over theme, layout, and behavior. Framework-agnostic web components ensure easy integration for any stack, with a dedicated React wrapper for component-based apps. Get started today and add rich, actionable notifications to your product, fast.
