btop vs HTTPie

btop is a free resource monitor for Linux and macOS that displays processor, memory, disk, network, and process activity. Its game-inspired menus, mouse support, and responsive interface provide ways to navigate system views and process controls. Users can inspect process details, filter or sort the list, view it as a tree, send signals, or pause the process list. Network graphs scale automatically; other displays cover disk activity and speeds, plus a battery meter. Users can choose graph symbols, create presets, and use theme files shared with bpytop and bashtop or a custom themes directory. GPU monitoring is supported on Linux and on macOS with Apple Silicon GPUs when built with GPU support. NVIDIA monitoring needs the nvidia-ml library, AMD needs rocm_smi_lib, and Intel needs SYSFS read permission. The project documents Linux and macOS installation, package installation for FreeBSD and NetBSD, and Homebrew for macOS and Linux. It recommends a terminal with 24-bit truecolor and wide-character support, a UTF8 locale, and a font covering specified Unicode blocks. The repository lists the Apache-2.0 license.

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.
