cmux vs Cursor
Cursor is an AI editor and agent platform. cmux is a native terminal and browser for running the agents and tools you choose. Many developers use both: Cursor for editing, cmux for supervising terminal agents.
Different layers
Use Cursor when you want AI inside the editor, Cursor CLI, browser tools, or cloud agents. Use cmux when you want a free, open source terminal to run and monitor CLI agents, dev servers, SSH sessions, and browser checks without making one editor, account, or cloud-agent runtime the center of every workflow.
| Dimension | cmux | Cursor |
|---|---|---|
| Primary surface | Terminal, browser, workspaces, splits | Editor, CLI, agent workspace, browser, and cloud agents |
| Desktop stack | Native Swift/AppKit macOS app built on libghostty | VS Code-based desktop editor; VS Code uses Electron |
| Agent choice | Any CLI agent | Cursor Agent across editor, CLI, cloud, and integrations |
| Workflow center | Bring your own terminal agent and keys | Cursor account, plans, editor, CLI, and cloud features |
| Source model | Free and open source GPL app | Proprietary Cursor product based on the VS Code codebase |
| Performance profile | Native Swift/AppKit terminal | Cross-platform editor plus local and cloud agent surfaces |
| Best fit | Supervising many shell-based agents | Writing and editing code with AI assistance |
cmux works beside any editor
cmux does not need to become your editor. You can keep using Cursor, Xcode, Neovim, VS Code, or JetBrains while cmux runs agents, tests, shells, browser panes, and remote sessions.
CLI agents stay portable
Claude Code, Codex, OpenCode, and other CLIs keep their own accounts, model choices, and configuration. cmux adds supervision without moving the agent runtime into a new hosted platform.
Terminal workflows need terminal controls
Agent work often involves test runs, logs, dev servers, SSH, and local scripts. cmux keeps those surfaces in one native app, then uses notification rings, Cmd+Shift+U, Cmd+Control+U, and the socket API to make the work controllable.
The combination is strong
A practical setup is Cursor for focused editing and cmux for parallel terminal agents. The editor stays clean while cmux tracks which autonomous sessions are running, finished, or blocked.

No. cmux is a terminal and browser workspace, so it works well beside Cursor or any other editor.
Can cmux run Cursor CLI?
Yes. Cursor CLI runs in cmux like any other terminal agent.
What does cmux add to Cursor?
cmux adds native terminal multitasking, visible agent workspaces, notification rings, unread navigation, and programmable browser and terminal control.
