DiskSlayer Disk Attribution

Find the background process secretly eating your disk and fix it

Problem

Mac users often find their disk mysteriously full without knowing which app is generating junk. One user discovered ToDesk's background process crash-looping and writing 1MB .dmp files repeatedly under /Library/Application Support—deleting them didn't help until an update; another only realized ToDesk was eating 188GB when the drive filled up. The built-in storage overview gives almost no visibility into developer caches, logs, or crash dumps.

Solution

A macOS disk attribution tool that aggregates the fastest-growing files by process and directory tree, focusing on crash dumps, logs, caches, container images, and AI models. It proactively flags abnormal generation patterns (like a process repeatedly writing .dmp files) and suggests safe cleanup and upgrade paths.

Users

Mac developers, designers, and heavy multitaskers—especially those running many background tools like remote control, sync clients, Docker, and AI apps.

MVP

Scan common hidden directories and rank by size and growth rate; attribute recently added large files to processes; apply rule-based cleanup suggestions for .dmp files, logs, node_modules, Docker images; preview before delete; menu bar live disk change indicator.

Revenue

One-time purchase ($9.99–$19.99) or annual subscription for continuous rule-set updates and scheduled scans; small in-app purchases for cleanup rule packs.

Why now

With more AI clients and remote tools installed, background disk writes are harder to control; the built-in tool still shows only a vague storage bar, leaving a gap a native indie app can fill.
