Better Resource Monitor
Lightweight macOS system monitor for troubleshooting CPU, memory, network, and GPU activity with minimal process footprint.
Processor, memory, network, and GPU activity in the macOS menu bar. No root helper, no extra background processes. Built in Rust with Tauri. On Apple Silicon it stays under 0.1% CPU and around 15 MB of memory.
GPU monitoring uses the public IOKit IOAccelerator interface, so the app ships fully sandboxed through the Mac App Store. Open source under the MIT license.
