btop

btop shows usage and stats for CPU, memory, disks, network, and processes in the terminal. The current README also carries a detailed policy on AI generated pull requests.

A resource monitor that covers processor, memory, disks, network, and processes. Written in C++ under Apache-2.0. The UI borrows a game inspired menu, supports the mouse across all buttons, lets you move through processes with the arrow keys, and makes filtering and sorting a few keystrokes. Selecting a process opens detailed stats, and signals can be sent straight to whatever you have chosen.

A tree view of processes, the ability to pause the list, an auto scaling graph for network usage, disk IO activity and speeds, a battery meter, selectable graph symbols, and custom presets. Themes are shared with bpytop and bashtop, so existing theme files mostly carry over. It is a tool with a lot of small conveniences on top of the core monitoring.

A notable chunk of the README's news section now deals with AI generated pull requests, since more of them have been arriving. Code produced by prompting an LLM, directly or through comment prompting, must be marked [AI generated]. Autocomplete suggestions used only for boilerplate do not count. Not disclosing gets a PR closed, actively hiding the use gets the account blocked, and vibe coded PRs where the author does not understand the code get dismissed.

Recent releases added GPU monitoring for Linux and platform support for OpenBSD, after macOS and FreeBSD support had already landed. Release binaries do not ship with GPU support enabled, because it depends on loading dynamic GPU libraries at runtime. The README is also upfront that Windows is not in the plans.
