AppControl vs btop

AppControl is a free historical Task Manager for Windows that records system activity and application behavior over time. It keeps approximately 72 hours of second-by-second history covering CPU, GPU, memory, disk, temperature, and app events. Executables are described in plain language with publisher, signature, and elevated-privilege information. Alerts can flag webcam, microphone, or location access, along with new or unsigned apps and silent updates. Users can disable an app, block a publisher, and create rules to stop software from returning. History is stored locally. An optional MCP server connects compatible AI clients after you enable it and approve data access; its nine tools are read-only and cannot change rules or configuration. A command-line tool shows live resource use and process events. AppControl supports modern Windows 10 and Windows 11, requires administrator privileges to install, and is not an antivirus replacement.

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.
