BlitzClean: Open-Source RAM Monitor and Disk Cleaner for macOS

X postVirgile RIETSCHTool

Virgile RIETSCH has launched BlitzClean, a free and open-source macOS utility designed to monitor RAM and clean disk space, tailored to identify resource-heavy developer workflows and AI agents.

Key points

  1. BlitzClean displays CPU, RAM, and free disk space in the macOS menu bar.
  2. It ranks applications and AI coding agents (such as Claude Code, Codex, and Cursor) by memory consumption, enabling users to pause or terminate forgotten sessions.
  3. The tool identifies storage usage and cleans caches, node_modules folders, simulators, Docker data, and old worktrees following user review.
  4. It is released under the MIT licence and operates entirely locally.
  5. The project was motivated by disk storage limits, unclear RAM usage, and Memory Clean 2 breaking on the macOS 27 beta (Golden Gate).

Why it matters

AI coding assistants and modern web development stacks can rapidly consume system memory and drive capacity. BlitzClean provides an open-source, local solution specifically tuned to developer-specific artefacts like container layers and dependency directories.

Analysis

As developers run multiple background agents alongside heavy toolchains, system monitoring needs to evolve beyond basic activity monitors. BlitzClean directly highlights running coding agents and development caches. Its strictly local operation and MIT licence make it a lightweight, privacy-preserving utility for macOS workstations.

Introducing BlitzClean ! A free, open-source RAM monitor + disk cleaner for Mac I built it based on 3 things: - I kept running out of storage - I never knew what was eating my RAM - Memory Clean 2 stopped working for me on the macOS 27 beta (Golden Gate) What it does: - CPU, t.co/mjECWiSdm0

  • @UllasSHR @virgilerietsch Bro I made an open source software recently and used Opus 5.5 for the video and the music it produces through writing code is so similar t.co/YqvI0n4CKq
  • @SuryaRajendhran @PreslavMihaylov @Joshua_WD @virgilerietsch you can try one of the coding agent workspaces if you're technical 1. hoplite 2. superconductor (disclaimer, I work here) 3. niteshift very developer focused products and much better than doing it on local
  • @PreslavMihaylov @SuryaRajendhran @Joshua_WD @virgilerietsch thanks, for now im looking at self hosting my agents vs using cloud agent products, but lets see how that goes
  • @Tech_girl @virgilerietsch Congratulations on the launch!
  • @pivi___ @virgilerietsch Très très stylé man! Je vais tester ça de suite Et la vidéo est super propre !
