# Canopy vs cmux for coding agents: terminal control or project workspace?

> A dated, source-backed comparison of Canopy and cmux across parallel CLI sessions, attention, browser preview, PR review, remote access, and platform fit.

Article date: 2026-09-28

cmux and Canopy both make multiple coding-agent terminals easier to manage. cmux is a Ghostty-based macOS terminal with programmable workspaces, notifications, an in-app browser, and SSH. Canopy is a cross-platform desktop project workspace around installed CLIs, local services, editing, Git, pull requests, and team context. Compare a full task loop, not a screenshot of tabs.

## What both products already do

Both run ordinary coding-agent CLIs in terminals, show multiple workspaces, put a browser near the terminal, surface agent attention, and expose branch or PR context. cmux's current README describes blue attention rings, notifications, vertical tabs with branch, PR, directory and ports, a scriptable browser, and hooks that can restore supported agent sessions. Canopy's current-main README describes real PTYs, an Agents rail, worktrees, detected dev-server URLs, Preview, and session-to-diff context. Neither product's overview proves that every CLI integration or installed release behaves identically. Test the CLI and version you actually use.

| Decision | Canopy | cmux |
| --- | --- | --- |
| Primary surface | Project workspace with terminals, editor, services, Git and PR | Programmable macOS terminal with panes and browser |
| Agent attention | Agents rail and project-aware attention signals | Notification rings, panel, and hook-driven agent state |
| Preview | Detected services, Preview, console/network, scoped feedback | Scriptable in-app browser beside terminal |
| Git and PR | Agent Workspace, diffs, worktrees, checks and PR context | Sidebar branch and linked PR status; compose review tools as needed |
| Remote path | PIN-enabled Remote on a running host; optional team relay | SSH workspace and iOS beta/mobile connection documented |
| Platforms | macOS, Linux, Windows release assets | macOS native app in current README |

## Where cmux is compelling

If you already work primarily in a terminal and want your own layout or scripts, cmux exposes a CLI and socket API for workspaces, panes, notifications, and browser actions. Its README describes direct SSH workspaces, Ghostty configuration compatibility, and a local tmux option for live detach and reattach. It is explicit that ordinary processes do not magically survive app quit; supported agent sessions can resume when hooks captured their native session IDs. This is a strong fit for a Mac developer who wants to assemble a personal workflow from terminal primitives and keep keyboard control central.

## Where Canopy adds a project layer

Canopy's current-main README puts a named project, components, saved local-service commands, files, editor, branch, diff, PR, research, and agent history around the terminal. It also documents optional encrypted team collaboration, PIN-protected Remote, local dictation on supported machines, and usage signals exposed by some CLIs. That can help a founder or reviewer who needs to see the running product and the proposed change without reconstructing them from shell history. Canopy is under active pre-1.0 development; its README may be ahead of the latest downloadable release, so verify the exact installer and platform before treating a feature as available to your team.

## Run the same fifteen-minute trial

Use the same repository, installed CLI account, and small task in both apps. Create one isolated checkout for a settings-page change and a separate read-only review session. In each product, identify which agent needs input, start the project's website command, open its current local URL, find the changed file and PR, and close and reopen the app. Record the branch and commit, elapsed setup and review time, any missing context, and whether the CLI conversation actually resumed. Keep the task and acceptance criteria fixed. A faster terminal launch or a denser dashboard matters only if it improves this completed workflow for you.

*Record observations instead of choosing from feature lists alone.*

| Checkpoint | What to record |
| --- | --- |
| Agent handoff | Project, CLI, checkout, exact waiting question |
| Running result | Command, reported URL, behavior you tested |
| Code review | Diff, PR head commit, checks, decision |
| Return after close | Layout, process state, and native CLI conversation state separately |

## Choose by the work you own

Choose cmux when a programmable macOS terminal, SSH, and a scriptable browser are the core of your day and you prefer composing the rest. Choose Canopy when you want the project, services, editor, agent activity, usage, Git review, and optional team handoff presented as one desktop workflow, especially across more than macOS. Both are open source: cmux's README describes GPL licensing and Canopy's README describes MIT licensing; inspect the actual license files if redistribution terms affect your choice. The honest question is which interface helps you complete and verify your own agent task with less lost context.

## Frequently asked questions

### Does cmux have an in-app browser and agent notifications?

Yes. Its current README documents a scriptable browser, notification rings and panel, and agent hooks. Test those features in the cmux build and CLI setup you plan to use.

### Can both run Claude Code and Codex CLI?

Both run installed terminal CLIs. Their richer attention, resume, usage, and edit-attribution integrations vary by CLI, hook setup, and release.

### Does closing either app keep my local agent process running?

Do not assume so. cmux documents layout restore and optional native agent-session resume, with separate tmux support for live detach. Canopy documents restorable sessions and app lifecycle behavior. Verify process state and CLI resume in your exact setup.

### Which is better for a noncoder?

A noncoder still needs a repository, CLI, runtime, and someone to review the result. Canopy exposes more project and review surfaces; cmux gives a flexible terminal and browser. Try the same bounded task and see which makes the run and final diff easier to inspect.

Canopy runs installed coding CLIs; CLI accounts, model selection, and provider billing remain separate. Check the installed release before relying on version-specific behavior.
