Scope of Control

Full desktop vs browser-only automation

Fazm controls your entire macOS environment - any app, any file, any window - through the accessibility API. MultiOn is constrained to the Chrome browser. If the task involves a native app like Figma, Xcode, Slack, or a local file, MultiOn cannot help. Fazm has no such boundary.

F
Fazm
  • Controls Finder, Terminal, Xcode, any native app
  • Reads and writes local files
  • Manages windows and system settings
  • Works across all macOS apps simultaneously
M
MultiOn
  • Limited to Chrome browser tabs
  • Cannot access native desktop apps
  • No file system access
  • Cannot control non-web software
Voice vs API

Voice-first consumer agent vs developer API

Fazm is built for non-technical Mac users who want to speak tasks and have them done immediately. MultiOn is designed for developers who want to embed browser automation into their own products via REST API. Both are capable, but they solve very different problems for very different audiences.

F
Fazm
  • Push-to-talk voice triggers desktop actions
  • No code required for consumers
  • Works out of the box on any Mac
  • Natural language with immediate results
M
MultiOn
  • REST API requires developer integration
  • Chrome extension for interactive use
  • Session management and API keys required
  • Built for embedding into other applications
Privacy

On-device processing vs cloud-routed sessions

When Fazm analyzes your screen, that happens locally on your Mac. When MultiOn automates a browser session, the session is routed through MultiOn's cloud infrastructure. Your web browsing activity, credentials, and interactions travel through their servers for the automation to work.

F
Fazm
  • Screen analysis runs entirely on device
  • No third-party server sees your desktop
  • Credentials stay in macOS Keychain
  • Open source - every action is auditable
M
MultiOn
  • Browser sessions proxy through MultiOn cloud
  • Web activity observed by MultiOn servers
  • Credentials used in automated sessions pass cloud
  • Closed source - no audit of data handling
Web Automation

Any-app control with web support vs web-only

MultiOn is optimized for web automation and has genuine strengths there - anti-detection, session management, and an API that developers can call programmatically. Fazm also automates web tasks (via browser DOM control) but is not specialized for high-volume scraping or API-driven web automation pipelines.

F
Fazm
  • Browser DOM control for web tasks
  • Pairs web actions with native app context
  • Voice-triggered web automation
  • Google Workspace native integration
M
MultiOn
  • Specialized anti-bot detection for scraping
  • Session replay and parallel session support
  • Built-in rate limiting and proxy management
  • Developer API for programmatic orchestration
