MacSentinel-Style Local Resource Doctor

Process diagnostics and app-aware cleanup for developers on macOS

Problem

Mac developers constantly face spinning fans, memory pressure, and disks clogged with caches, but Activity Monitor only shows raw data without telling you which project or toolchain is to blame. Someone built a local utility combining process/resource diagnostics with application-aware cleanup and made their first $150 within 24 hours of launch, showing the pain is real and people pay. Existing cleaners target everyday users and lack developer context.

Solution

A local macOS tool that aggregates processes and resource usage by project, language runtime, and dev tooling; identifies safely removable caches, derived data, stale build artifacts, and simulator images; and previews impact before cleanup. Offers one-click release and diagnose-only modes.

Users

Developers, designers, and heavy multitaskers on Mac, especially those whose disks keep filling up

MVP

Aggregate CPU/memory by process tree; scan common dev cache directories; preview and undo before cleaning; menu-bar live overview; fully local with no data upload

Revenue

One-time purchase desktop app with a trial; premium adds auto-cleanup rules and team deployment

Why now

Nearly all dev workflows are local and multi-tool, causing heavy resource contention, while big-name cleaners ignore developer scenarios, letting a solo dev ship a SwiftUI buy-once tool in weeks
