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.
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.
| 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.
