# Paneflow vs iTerm2

> Paneflow is for supervising several CLI agents across panes, branches, MCP context, and diffs on Linux, macOS, and Windows. iTerm2 is the deeper macOS terminal: tmux control mode, shell integration, Python and AppleScript automation, inline images, AI Chat, and Claude Code Workgroups.

## Highlights

### Work across Linux, macOS, and Windows

Paneflow ships Linux x86_64/aarch64, macOS Apple Silicon, and Windows x64 builds. iTerm2 is macOS-only.

### Supervise several coding agents

Paneflow has 16 launcher buttons and broader multi-agent status tracking. iTerm2 adds Claude Code Workgroups and AI orchestration inside macOS.

### Expose pane context read-only

Paneflow ships read-only MCP tools for list_panes, read_pane, and search_pane. iTerm2 can use MCP-style AI tool calls, but this checkout does not show a native read-only MCP pane server.

## The important differences

The split is not terminal quality vs agent quality. iTerm2 is a powerful AI-aware macOS terminal. Paneflow is the cross-platform workspace around local CLI agents, worktrees, MCP pane context, and diffs.

| Topic | Paneflow | iTerm2 |
|---|---|---|
| Platforms | Linux x86_64/aarch64, macOS Apple Silicon, Windows x64 | macOS only |
| Best fit | Multi-agent panes, branches, MCP context, diff review | macOS terminal depth: tmux, shell, scripting, images |
| Coding agents | 16 launchers; any CLI in a real pane | AI Chat, orchestration, Session Status, Workgroups |
| Agent/workspace status | thinking, waiting, finished, errored, stalled | Session Status + Workgroups in 3.7 beta |
| MCP pane context | Read-only MCP: list_panes, read_pane, search_pane | MCP tools in AI flows; no read-only pane server found |
| Worktree diff/review | Worktree diff columns + review prompt in pane | Workgroups drive Claude Code diff/review flows |
| tmux integration | No tmux control mode | Native tmux control mode (-CC) |
| Terminal automation | JSON-RPC control plane + shell CWD | Python, AppleScript, triggers, selection, history, images |

Versions checked: Paneflow v0.7.6 (July 2026). iTerm2's README advertises stable 3.6; this checkout includes 3.7 beta notes dated April 20, 2026. This page was checked against both local repositories on July 2, 2026.

## Which tool should you use?

Choose based on what structures your daily work: multiple CLI agents, or a deeply configurable macOS terminal.

### Choose Paneflow if

- You need Linux x86_64/aarch64, macOS Apple Silicon, or Windows x64 builds
- You run multiple CLI agents beyond Claude Code and want to track their status
- You want agents to read other panes through Paneflow's read-only MCP bridge
- You want a workspace built around tasks and agents

### Choose iTerm2 if

- You work exclusively on macOS and want a very mature terminal
- You rely on native tmux integration (control mode -CC), the Python API, or AppleScript
- You need triggers, smart selection, semantic history, or inline images
- You want AI Chat and Claude Code Workgroups in your macOS terminal

## Frequently asked questions

### Is Paneflow a fork of iTerm2?

No. Independent codebases, zero shared source. iTerm2 is Objective-C + Swift on AppKit and macOS-only; Paneflow is Rust on Zed's GPUI engine with upstream alacritty_terminal and current Linux x86_64/aarch64, macOS Apple Silicon, and Windows x64 builds. Different stacks, different goals.

### iTerm2 has AI now. What's the difference?

iTerm2 is more than a chat window: AI Chat can inspect linked terminal state, orchestration can operate iTerm2 with permission, and the 3.7 beta adds Claude Code Workgroups, Code Review, and Clippings. Paneflow solves the adjacent cross-platform problem: many local CLI agents, visible panes, branch/worktree context, read-only MCP pane access, and in-app diff review.

### Does Paneflow run on Linux? iTerm2 doesn't?

Yes. Paneflow ships Linux x86_64/aarch64, macOS Apple Silicon, and Windows x64 builds today. iTerm2 is macOS-only; if Linux or Windows is in your daily workflow, Paneflow is the only one of the two that runs there.

### Does iTerm2 have an MCP server like Paneflow?

Not in the same sense. iTerm2 has MCP-related AI provider plumbing, but this checkout does not show a native read-only MCP server that exposes terminal panes. Paneflow ships that bridge itself: list_panes, read_pane, and search_pane expose panes as untrusted read-only context to capable agents.

### What does iTerm2 do better than Paneflow?

iTerm2 is stronger when the terminal itself is the job: tmux -CC, Python API, AppleScript, deep shell integration, inline images, hotkey windows, broadcast input, session restoration, browser sessions, AI Chat, and Claude Code Workgroups on macOS. Paneflow is narrower: local multi-agent supervision, MCP pane context, and worktree diff review across Linux, macOS, and Windows.
