DevCleaner

DevCleaner is a macOS menu bar application that scans caches left by developer tools and AI applications then removes selected items after review. It addresses the accumulation of large cache directories from multiple toolchains that consume significant disk space on Mac systems.

The application scans roughly 22 toolchains that include Xcode, Docker, npm, Gradle, Cursor, Claude, and Ollama. It identifies specific cache locations such as Xcode DerivedData, Docker images and dangling layers, dormant node_modules directories, local Ollama model weights, and Cursor workspace data. Each discovered cache receives one of three classifications: Safe, Warning, or Danger. Safe items are pre-selected for removal, Warning items require user consideration, and Danger items are never pre-selected to avoid deleting files still required by active projects. A single interface displays all results from one scan, allowing users to review classifications and clean chosen items together.

It is delivered as a menu bar app for macOS. The tool is presented as a one-time purchase available through OneTimePay.app.

The classification model is intended to distinguish temporary caches from data that projects or applications may still need, enabling developers to reclaim disk space without manual identification of each cache directory.
