DiskCheckup Mac disk diagnostics for devs

An explainable disk audit for bloated MacBooks that tells developers what is safe to delete

Problem

Long-time Mac users accumulate node_modules, Xcode caches, Docker images, simulators, and build artifacts. Apple's built-in storage manager is vague, and third-party cleaners often delete the wrong things or cost too much. Developers are already building and sharing macOS disk diagnostics, which shows this is a frequent, hard requirement.

Solution

Scan the disk and group usage by developer toolchain: Xcode, Docker, Node, Python, simulators, logs, etc. Each item shows size, last access time, and a clear safety verdict. Risky deletions go through Trash or a quarantine step with undo.

Users

Developers, designers, and indie makers who use a MacBook as their main machine and juggle multiple project environments

MVP

Scan and visualize only, no auto-delete; group usage by dev toolchain with plain-language explanations; highlight common space hogs like node_modules, DerivedData, and Docker images; one-click Reveal in Finder; export a shareable report

Revenue

Free scan plus paid auto-cleanup and scheduled audits; or a one-time purchase

Why now

The Mac remains the default dev machine, and local models, datasets, and containers are pushing disk pressure higher, while existing cleaners are either too heavy or too opaque. A transparent, explainable lightweight alternative fits an indie dev well
