Fazm vs Claude Cowork

A free, open-source AI agent for your real desktop vs a paid sandboxed VM. Both use Claude - but the approach to controlling your computer could not be more different.

The core difference

Real desktop vs sandboxed VM

Claude Cowork runs inside a Linux VM on your Mac. It can install packages and run scripts inside that sandbox, but it cannot touch your real desktop. Fazm controls your actual macOS environment - your real apps, your real browser, your real files.

Claude Cowork

Sandboxed, limited, paid

Sandboxed VM environment
  • Runs in a Linux VM - not your real macOS
  • Cannot open or control native apps like Figma, Slack, or VS Code
  • No access to your real browser sessions or cookies
  • Only sees folders you explicitly mount
  • Cannot move your mouse or type on your keyboard
  • Text-only - no voice commands
  • Requires $20+/month Anthropic subscription
  • Proprietary and closed source

Safe, but isolated.

Cowork keeps you in a sandbox. Great for safety, but it cannot actually control your computer or automate your real workflow.

Your real desktop, not a sandbox

About each product

Claude Cowork

by Anthropic

Launched January 2026 as part of Anthropic's Claude desktop app. Cowork spins up a sandboxed Linux VM on your Mac where Claude can autonomously complete multi-step tasks - organizing files, analyzing datasets, writing code, and coordinating workflows. You mount specific folders into the VM, and Claude works within that isolated environment. Requires a Pro ($20/mo), Max ($100-$200/mo), Team, or Enterprise subscription. Supports MCP connectors for Google Workspace and DocuSign.
