StorageRadar

Problem

macOS users — especially developers — accumulate gigabytes of invisible waste: Xcode device support files, npm caches, Docker images, Gradle build artifacts. Existing tools either send data to the cloud, miss developer-specific cleanup scenarios, or lack the visualization to understand storage at a glance.

Solution

StorageRadar is a fully local storage analysis and cleanup tool for macOS, built specifically with developers in mind. It visualizes disk usage with an interactive treemap and sunburst chart, surfaces developer environment waste with smart detection, and provides a safe cleanup workflow with dry-run support.

Engineering Highlights

• Interactive visualization: treemap and sunburst modes for intuitive storage navigation.
• Developer-aware cleanup: detects and safely removes Xcode device support, Derived Data, npm/pnpm/Yarn caches, Docker volumes, Gradle caches, and more.
• App uninstaller: deep uninstall with risk labels — identifies associated files, caches, preferences, and support files per app.
• Snapshots & diffs: periodic storage snapshots with diff comparison to track what grew.
• MCP integration: local Model Context Protocol endpoint at 127.0.0.1 that exposes storage analysis to AI agents — the first macOS utility with native MCP support.
• Privacy-first: zero telemetry, zero cloud sync, zero remote connections. Everything runs locally.
• Dry-run by default: all cleanup operations show a preview before any deletion.

Platform Constraints

Accessing certain protected directories requires explicit user-granted permissions via macOS security APIs. The app is sandboxed and requests only the permissions it needs, scoped to user-selected paths.

Outcome

Currently in active beta with weekly updates. Planned as a one-time purchase on the Mac App Store with three tiers: Free, User, and Developer. No subscription.
