Postman vs ReadMe
Side-by-side comparison of features, pricing, ratings, and alternatives.
Postman is an API platform for building and using APIs. Postman simplifies each step of the API lifecycle and streamlines collaboration.
ReadMe is a documentation platform built for teams that need to publish interactive, developer-facing API references and product docs. It generates interactive API explorers from OpenAPI specs, layers on a visual API Designer, and syncs bi-directionally with GitHub and GitLab so docs stay aligned with code changes. Beyond static reference pages, ReadMe adds real-time collaborative editing, branching and review workflows, reusable content blocks, and AI tools such as an AI Writer, a style linter, and an in-docs assistant. Enterprise customers get SSO, role-based access, audit logs, and SOC2/GDPR-aligned compliance features, and the platform is used by companies including NVIDIA, Amazon, and PagerDuty.

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.
