Scape vs cmux
cmux, from Manaflow, is a native macOS terminal built on Ghostty for AI coding agents, with vertical tabs and notifications.[1] Here is how it compares with Scape, with a source for every claim about cmux.
| Feature | Scape | cmux |
|---|---|---|
| Agents | ||
| Agents | Claude Code, Codex, Copilot, Cursor, OpenCode, pi, omp and Kimi Code, on your own subscriptions. | Any CLI agent, with resume hooks for Claude Code, Codex, OpenCode, Amp, Cursor CLI, Gemini, Copilot, Factory and others.[1] |
| Manager agent (Argus) | Argus reads your mission, starts child agents in their own worktrees, checks on them, and keeps a log table. You choose which agent and model its children run on, and can restart it on another agent without losing them. | No. |
| Agent rooms | Chat rooms where agents and people work one problem together, such as Claude and Codex debating an approach. | No. |
| Messages between sessions | One agent can message or direct another session. | The cmux agent message command sends a message to the agent in another workspace, delivered through that agent's hooks.[3] |
| Agent review | Adversarial review: a second agent reviews the first one's diff (/scape-codex-review ships with Scape). | No. |
| Watchdogs | Supervisors that spot stuck sessions and auto-answer questions and permission gates (Claude Code). | No. |
| Automation | ||
| Playbooks | Step-by-step automations that chain shell commands, agent prompts, HTTP calls and Scape tools. Lock one and it runs as a fixed script. | No. |
| Scheduler | A per-project calendar that runs playbooks and messages Argus, once or daily, weekly or monthly, while Scape is open. | No. |
| Triggers | Run a playbook or prompt Argus when a webhook arrives, an integration record changes, a table query matches, or a calendar event happens. You arm each one. | No. |
| Working with people | ||
| Flight Plans | One shared, end-to-end encrypted document where you, a teammate and both your agents turn open questions into decisions and tasks. Share it by link and approve each person who asks to join. | No. |
| Encrypted chat | End-to-end encrypted group and one-to-one rooms. Messages are never stored on a server. | No. |
| Sharing | Drag notes, playbooks and tables into an encrypted chat to share them. | No. |
| Workspace | ||
| Notes | Rich-text notes with version history, embedded charts and full-text search, synced through your iCloud. | No. |
| Tables | SQLite-backed tables your agents and playbooks read and write, viewed as a table, kanban or gantt. | No. |
| Charts | Bar, line, area, scatter, pie and KPI charts built from your tables, embeddable in notes. | No. |
| Custom Apps | Small apps built from a JSON spec, kept in your project. | Custom sidebars (beta): user-written SwiftUI-style files that render as native sidebar UI, bind to live cmux state and run cmux commands.[4] |
| Integrations | Jira, GitHub, Slack, Notion, Linear, ServiceNow, Bugsnag, Datadog, or any HTTP source, in your sidebar. | GitHub pull request status in the sidebar, using the GitHub CLI; cmux pr attaches a PR to a workspace.[5] |
| Dev tools | ||
| Worktrees | A git worktree per session, with a post-create hook you set per repo or globally. | No. |
| Code editor | Monaco, with 60+ languages, a diff view, Vim mode and LSP. | A file editor with syntax highlighting, and a separate diff viewer.[6] |
| Browser | A built-in browser your agents can drive: screenshots, clicks, forms and scraping. | A scriptable browser pane.[1] |
| Dev servers | A live browser preview paired with each server. Cmd+click jumps to the source, and each worktree gets its own port. | The sidebar lists each workspace's listening ports, and a browser pane can show the dev server beside the terminal. Dev servers run in ordinary terminals.[7] |
| Spectator mode | Every file an agent edits opens live in the editor, so you can follow along. | No. |
| The basics | ||
| Status | In active development. | Latest release v0.65.2.2 on 2026-10-27.[6] |
| Where agents run | On your Mac. Claude Code sessions can also run on a saved SSH host. No hosted agents. | On your Mac and over SSH. Paid plans add cloud machines.[2] |
| Platform | macOS. Claude Code sessions can also be driven from the Claude mobile app through Remote Control, opt-in per project. There is no Scape mobile app yet. | macOS, with an iOS app in TestFlight beta.[1] |
| Price | 14-day free trial, no account or card. Then Pro at $9.99 a month or $99 a year; you bring your own agent subscriptions. | Free. Pro is $50 a month ($480 a year), and paid plans add cloud machines.[2] |
| Open source | No. | The app is GPL-3.0-or-later; the server and relay code is under the Business Source License 1.1.[1] |

“No” means it isn’t in cmux’s app or docs: we checked their own site, docs, changelog and repo on , and only count a feature that’s built in and does the same job. If that’s changed, tell us and we’ll update the page.
Why people pick Scape
- Argus runs the fleet for you: it starts child agents on whichever agent and model you choose, checks on them, and can set one agent to review another's work.
- Everything around the agents is in one app: notes, tables, playbooks, Custom Apps, an editor, a browser paired with your dev servers, a scheduler and triggers, and Flight Plans and encrypted chat with your team.
- A worktree per session with a setup hook per repo, and dev servers that each get their own port.
Where cmux is stronger
- The app is free and open source.[2][1]
- Cloud machines on paid plans.[2]
- An iOS app, in TestFlight beta.[1]
