HTTPie – API testing client that flows with you | WarmIndex

HTTPie is a modern, user-friendly HTTP and API testing client available as a CLI tool, desktop app, and web app, designed for developers working with APIs and web services.

🚀 Overview

HTTPie makes interacting with APIs intuitive and enjoyable, whether from the command line, desktop, or browser. Originally a CLI alternative to curl, it has evolved into a full suite with graphical interfaces that maintain the same human-friendly approach.

The project solves the problem of complex, verbose syntax in tools like curl, providing beautiful, colorized output, smart defaults, and natural language-like requests. It's built for developers, testers, DevOps engineers, and anyone debugging HTTP servers or APIs.

HTTPie was created by Jakub Rożtocil to bring joy to CLI HTTP interactions and has grown into a company-backed tool loved by engineers at top tech companies.
