Fazm vs Claude Code
Same Claude Code engine, but your sessions survive restarts, every chat forks in one click, and the context never gets compacted away. Plus voice and Mac-wide control.
Feature-by-feature comparison
How Fazm and Claude Code stack up across every dimension.
Your sessions survive a restart. Every window comes back.
Restart your Mac with Claude Code open and every active session is gone. No history, no branch state, nothing to resume. Fazm restores every chat window and every conversation exactly where you left off, automatically. The agent loop comes back with full memory of what you were working on.
- Auto-saves every chat window
- Restores all windows on boot
- Full conversation history intact
- Pick up mid-task after a reboot
- Sessions live in terminal memory
- Restart kills every active chat
- Manual /resume required if logged
- Lost context on crash or update
One button to fork any chat into a new window.
Want to try a different approach without losing your current thread? In Claude Code you exit, find your session ID, resume on a branch, and hope you copied the right state. In Fazm you click fork. A new chat window opens with the full prior context, ready to diverge. Experiment freely, the original stays untouched.
- One-click fork from any chat
- New window with full context
- Run parallel approaches side by side
- Original chat stays untouched
- Multi-step session resume
- Manual branch tracking
- No native parallel-chat UI
- Easy to lose track of which branch
Never lose context to a compact again.
Claude Code compacts long sessions once they approach the context limit. The model summarizes earlier turns and drops detail, and you find out by the agent forgetting the exact decision you made an hour ago. Fazm keeps the full chat history live in context for the entire window's lifetime. What you said is what the agent still sees.
- Full chat history always in context
- No silent summarization step
- Nothing gets dropped or lossy
- Long sessions stay coherent
- Auto-compacts on context fill
- Earlier turns get summarized away
- Decisions and edge cases get lost
- Agent forgets what you decided
Voice, browser, native apps — not just the shell.
Claude Code lives in a terminal. It can edit files and run shell commands, but it cannot click in your browser, control Figma, send a Slack message, or pull a card off your Linear board. Fazm runs the same Claude Code engine and reaches the rest of your Mac through MCP, accessibility APIs, and computer-use tools. Voice in, agent acts everywhere.
- Push-to-talk voice input
- Controls browser DOM + cookies
- Drives any native macOS app
- Same Claude Code engine underneath
- Terminal text input only
- No browser DOM access
- Cannot touch native apps
- Shell-bound by design
About each product
Claude Code
by Anthropic
Anthropic's terminal-based coding agent. Runs Claude Sonnet, Opus, and Haiku as an autonomous coding assistant inside your terminal. Powerful agent loop, but each session is tied to a single terminal window, sessions vanish on computer restart, forking a conversation requires a multi-step workflow, and long sessions get auto-compacted (summarized) once they hit the context limit, dropping detail you may still need.
Fazm

An AI computer agent for macOS that goes beyond the browser. Controls your mouse, keyboard, browser DOM, and native apps - all triggered by voice.
