# Jharu: Open-Source Disk Cleaner for Developers Clean up unnecessary files left by machine learning and developer tools. - **Source:** [Hacker News: Show HN](https://news.ycombinator.com) - **Published:** 2026-07-24 - **Topic:** [Data & AI](https://brifing.si/c/data-ai) - **Original article:** - **On Brifing:** https://brifing.si/s/b545b37b-ecf2-484f-b2ec-ffee566c950e ## What is Jharu? Jharu is a disk cleanup app specifically designed for software developers and machine learning engineers. Unlike general disk analyzers, Jharu understands what the data actually is and cleans it safely. ## What Problems Does It Solve? Jharu cleans up large model caches left by tools like Hugging Face and PyTorch, unnecessary files from package managers like npm and pip, and remnants of long-uninstalled applications. ## Features Jharu distinguishes between used and unused machine learning models. It also scans developer caches and provides safety ratings for each item. ## Python Environments Jharu finds every virtualenv and conda environment, shows the size of packages inside them, and calculates the cost of duplication across environments. ## Deep Clean Jharu performs a full disk analysis, sizing folders based on their contents and classifying them as system, application, or developer data. ## Junk Files Jharu cleans up downloaded installers, old device backups, logs, and large files untouched for months. ## Desktop Cleanup Jharu filters screenshots and clutter on your desktop by type and age, archiving them to a folder by default. ## Browser Cache Jharu detects Chrome, Edge, Firefox, and other browsers, separating safe-to-clear cache from data that deserves review. ## Uninstaller Jharu lists installed applications and their accumulated data across the system. On Windows, it reads the registry, and on macOS, it removes the bundle. ## Drive Health Jharu shows the capacity and SMART status of each drive and provides a fill forecast based on daily capacity readings. ## Sources covering this story - https://github.com/riponcm/Jharu — --- _Summary written by Brifing from the original reporting.
