Overview
Description

Courier is a multichannel notification platform that lets developers send email, push, SMS, in-app, and chat messages through a single API and journey builder, rather than integrating separately with each channel provider. It positions itself as "the messaging platform for humans and AI agents," adding an AI Agent node and AI-powered translations to its journeys and broadcast tooling. Note: the product's original domain trycourier.com now permanently redirects to courier.com. The platform includes an inbox component for in-app notifications, user preference management, and observability integrations, with pricing based on message volume rather than seats or channel count. The free Developer tier includes 10,000 sends per month with journeys, broadcasts, an MCP server, a CLI, and SDKs; paid usage is billed per send, and Enterprise adds dedicated support, RBAC, SLAs, and EU data residency.

Novu is an open-source notification and agent communication infrastructure designed to streamline how software products and AI agents interact with users. It provides a unified API to manage and dispatch multi-channel communications across various messaging mediums.
