rtop is a system montior inspired by gtop implemented in Rust.

Supports Linux and MacOS (other *nix systems may work but not tested)

System monitoring is handled by sysinfo and the UI is handled by tui-rs.


The application is distributed via cargo. Its recommended you install cargo using rustup.

Once installed you can install rtop using the following:

cargo install rtop

To install the GPU monitor first you must have a NVIDIA Driver installed and nvidia-ml

Next you can install using

cargo install rtop --features gpu-monitor

If you are using rtop on a laptop you may also like a battery monitor. This can be enabled with

cargo install rtop --features battery-monitor


To quit press q
