Courier vs Postman
Side-by-side comparison of features, pricing, ratings, and alternatives.
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.
Postman is an API platform for building and using APIs. Postman simplifies each step of the API lifecycle and streamlines collaboration.
Free for individuals and small teams; paid plans start at $14/user/month.

Postman Reviews
4.5 (2)Solid choice
I switched to Postman last quarter and haven't looked back. Good team collaboration features. One minor gripe: team plans get pricey at scale, but it hasn't been a dealbreaker. Would recommend to anyone considering it.
Great tool for development
Been a daily user of Postman for a while now. Free tier covers most individual needs. No major complaints so far. Would recommend to anyone considering it.
