FindDiskKiller is a native macOS disk activity monitor that reveals which apps and AI coding agents are driving reads and writes. Track per-process disk I/O, CPU and network activity, inspect live file access, trace folders, and view SMART/NVMe drive health. Completely free and open source.
Hi Product Hunt!
I built FindDiskKiller to answer a simple question: what is hammering my Mac's disk right now?
AI coding agents can generate a surprising amount of disk activity through builds, caches, logs, dependency downloads, and runaway processes. macOS Activity Monitor shows overall disk usage, but I wanted a faster way to identify exactly which process is responsible and what files it is touching.
FindDiskKiller provides:
• Real-time disk reads and writes by app
• CPU and network activity
• Live file access inspection
• Folder-level tracing
• SMART and NVMe drive health information
The app is completely free and open source. I would especially appreciate feedback about which views are most useful and what would make unusual disk activity easier to diagnose.
