AppControl vs iotop

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.

iotop is a free Linux program that identifies processes generating high input/output activity and lists them by I/O usage. The display can show accumulated I/O or bandwidth, with optional read, write, swap-in and I/O-percentage columns. Monitoring can target selected process IDs or users, or show processes and threads across the machine. Interactive and batch modes support iteration counts, configurable delays and timestamps in batch output. Command-line filters narrow processes by TID or command using a regular expression. Installation guidance covers Debian-derived distributions, Fedora, CentOS/RHEL, Void, Arch and Alpine Linux; source builds use make after development dependencies are installed. The project is GPL-2.0+ licensed, but installation and use require root access. Version 1.31 is listed as the latest release. Its tag has a verified committer signature, although the signing key has expired.
