HTTPie vs OpenReq

HTTPie is an API testing client with a command-line tool and a graphical app for desktop and web. HTTPie for Terminal helps test and debug APIs, HTTP servers, and web services. Its features include expressive syntax, JSON, formatted and colorized output, persistent sessions, forms, file uploads and downloads, HTTPS, proxies, authentication, and custom request data and headers. GraphQL is supported. The Desktop and Web app includes AI-assisted work, spaces, collections, tabs, variables, environments, request previews, and autosave with realtime sync across devices. It can be used offline without an account, so requests can be prepared and previewed without sending them. Dedicated desktop versions are available for Mac, Windows, and Linux; Mac downloads cover Intel and Apple Silicon. The maker lists CLI installation options for any operating system. HTTPie for Web & Desktop is in public beta, and HTTPie for Terminal is an open-source CLI client. Both plans are listed at free.

OpenReq is a free, community-driven API testing application released under the MIT License. It runs as a self-hosted web application, a standalone desktop application, and a Windows client. HTTP, WebSocket, and GraphQL requests are supported as first-class request types, with visual test flows, collection runs, assertions, scripts, delays, conditions, loops, and reports. Automated test runs and API documentation are included, and API testing has no stated usage limits. Collections can become read-only public documentation links, optionally protected by passwords; viewers do not need accounts. OpenReq generates request code for cURL, Python, JavaScript, Go, Java, C#, and PHP. Integrations include Ollama, Postman, OpenAPI, raw cURL, Chrome, and Electron. Ollama can provide local AI features without a cloud API key or sending data away from the machine. The Windows desktop client is frontend-only and needs a separately hosted backend. Most endpoints use JWT bearer authentication, while local proxy setup uses HMAC-signed tokens.
