CmdBrief vs Emdash: worktrees, or a workspace?

The short answer

Pick Emdash when the bottleneck is parallelism inside a repository: several agents working at once, each isolated in its own worktree so they cannot collide on disk, diffs reviewed side by side, a pull request opened from the app. It is free, the source is Apache-2.0, it runs on three operating systems and on remote machines over SSH, it pulls tasks straight out of Linear, Jira, GitHub and others, and it drives far more agent CLIs than CmdBrief does.

Pick CmdBrief when the bottleneck is across products: several things you are responsible for, each with its own repos, tasks, terminals and browser tools, and six agent CLIs between them whose attention and provider usage you need on one screen. Apple silicon, macOS 26+, one paid plan, no free tier, and worktrees only for a lead agent’s crew builders, not per task.

A mixed setup is coherent. Emdash’s worktrees are ordinary Git worktrees under ~/emdash/worktrees, and CmdBrief opens ordinary checkouts, so one can do the branch-level parallelism while the other holds the portfolio view. If you want a third shape in the same family, CmdBrief vs Conductor covers the macOS-only, review-first version of this idea.

The data behind this comparison

What Emdash is for

From Emdash’s overview, tasks, providers, in-app browser, changelog and README pages, read on 2026-09-29:

• A worktree per task, created for you. “Each task gets its own git branch and worktree, keeping changes isolated until you merge.” Local worktrees default to ~/emdash/worktrees; remote SSH projects put them under .emdash/worktrees in the remote project. You can switch worktrees off and work on the checked-out branch, with a warning that changes will not be isolated.
• 35 agent CLIs, detected automatically. “Emdash supports 35 coding agent CLIs. Install or set up any of them and Emdash detects it automatically.” The list includes every CLI CmdBrief supervises and many it does not — Amp, Antigravity, Devin, Droid, GitHub Copilot, Goose, Junie, Qwen Code and more. The overview page says 34; the Providers page says 35. Either way it is a much longer list than six.
• Hook-based status. “Emdash tracks agent activity and supports notifications with lifecycle hooks, when the agent is working, awaiting input, or done,” for roughly twenty of those providers. Resume is supported for a similar set, and terminal state is saved so “close and reopen Emdash, and agents resume where they left off.”
• Review, pull request and CI in one place. Diffs across agents side by side, pull requests opened from the app, and GitHub Actions check runs monitored inside it.
• Issues in, work out. Tasks can be created from Linear, Jira, GitHub, Notion, Asana, GitLab, Forgejo and others, so the agent starts with the ticket as context.
• Remote development. SSH and SFTP to your own machines with agent, key or password authentication and credentials in the OS keychain, plus tmux sessions that survive reconnects.
• An in-app browser and a file editor. Persistent browser profiles per tab with their own cookies and storage, opened inside a task with ⌘⇧B, and tabs saved with the task view.
• Automations. Scheduled recurring agent runs with history, reruns and reviewable tasks.
• Free, Apache-2.0, local-first. “App state is stored in a local SQLite database, and Emdash does not send your code or chats to Emdash servers.” Telemetry is optional. There is an Emdash Cloud and an Emdash Enterprise, both contact-sales; emdash.com/pricing returns 404.

That is a large product that ships often — its changelog lists eight releases between 2026-08-28 and 2026-09-27 — and concede it plainly: on raw agent coverage, platform coverage and Git lifecycle, Emdash is ahead.

What CmdBrief is for

CmdBrief is a native Rust macOS app for the founder running several products. Each product gets a persistent workspace: agents, tasks, terminals, files, a diff viewer, and browser panes, with saved layouts that come back the way you left them. The sidebar rolls attention up across all of them.

It supervises Claude Code, Codex, Grok CLI, Kimi CLI, OpenCode, and Cursor CLI with the same working / needs-action / completed / failed states, and shows each vendor’s usage windows side by side where the provider reports them (Claude Code 5-hour and weekly, Codex weekly, Grok CLI weekly credits, OpenCode Go rolling / weekly / monthly, Cursor CLI monthly Cursor-models and Other-models pools; Kimi CLI exposes none). Session resume lists local threads across those CLIs.

In the Standard view, Claude Code, Codex, Grok CLI and OpenCode run as agent panes that draw the conversation, edits and questions instead of a terminal. A lead agent (Claude Code or Codex) can start a crew of Claude Code, Codex and OpenCode agents in one tab, each on a Core, Standard or Light tier of model and effort, with progress counted in plan steps and the questions that need you in one Needs you list.

The terminal is a hand-written VT emulator with a GPU text path, and the browser panes are embedded macOS webviews, so the staging site you check after every deploy lives in the product.

Constraints that are real: Apple silicon, macOS 26+, local-first, generally available since 2026-08-06. One plan, CmdBrief Pro, display prices €29.99/mo or €299.90/yr, 14-day money-back, no free trial. It gives a lead’s code builders their own git worktrees when several share a repo; for sessions you open yourself, pair it with claude --worktree if you need isolated checkouts. It does not resell agent provider plans.

Task-scoped or product-scoped

This is the whole comparison, so it is worth being precise instead of flattering.

In Emdash’s model the durable object is the task. You click Add Task, pick a branch, an issue or a pull request, pick a provider and a model, and the app prepares a worktree and spawns the agent in a terminal. Everything that belongs to that work — the conversation, the diff, the browser tabs, the checks — hangs off the task. When it merges, the reason for the worktree is gone. That is a clean unit, and it is deliberately temporary.

CmdBrief’s unit does not go away. A product workspace is the thing you return to: the same repos, tasks with acceptance criteria, terminals, browser panes and layout, whether you last touched it this morning or three weeks ago. The question it is built to answer is not “which branch is ready” but “which of the five things I am responsible for needs me, and which provider window am I about to run out of”.

Be fair to Emdash here: it does have a level above the task. Projects are first class, it supports multiple GitHub accounts with a different account per project, and remote projects live beside local ones. What we did not find on its docs is a persistent per-product home carrying pinned tasks, a saved pane layout and provider usage — so that row is a “partial”, not a “no”, and this paragraph is the reason.

Where they overlap

The overlap is larger than anything else on this hub. Both are desktop apps that run several agent CLIs at once. Both give each agent a real terminal. Both put a diff next to the agent that produced it. Both ship an in-app browser with persistent profiles for previewing the app you are building. Both are local-first: Emdash keeps state in a local SQLite database and says it does not send your code or chats to its servers; CmdBrief keeps repos and workspace state on your machine, checks your subscription against cmdbrief.com, and sends redacted crash reports to Sentry in the EU.

Both also detect installed CLIs and manage hook files for them. Emdash “installs marker-tagged entries in the agent’s user-level config” that “silently do nothing when the agent runs outside an Emdash session”; CmdBrief passes its hooks to Claude Code and Codex on each launch, manages its own blocks in the hook files of Grok, Kimi and Cursor CLI, and falls back to process and screen detection for OpenCode, which has no hook API. Two apps that both write hooks for the same CLI is worth knowing about before you install both.

Emdash goes further on Git lifecycle, agent count, platforms, remote execution, issue trackers, scheduling and cloud. CmdBrief does not claim any of those. CmdBrief goes further on product-level supervision and multi-vendor usage windows. We found no usage or limit display on Emdash’s docs or changelog — which makes that a dash for Emdash, not a no. The GUI comparison covers the wider field.

What Emdash does that CmdBrief does not

• It is free and Apache-2.0. CmdBrief has one paid plan and no free trial, and it is not open source.
• Windows and Linux — Windows x64, Linux x64 and ARM64 — plus Intel Macs. CmdBrief is Apple silicon on macOS 26+ only.
• A worktree and branch per task, created automatically. CmdBrief creates them only for the code builders a lead agent starts; otherwise you bring checkouts, or run claude --worktree in a pane.
• Far more agent CLIs — 35 on the Providers page, against CmdBrief’s six. If your stack includes Amp, Antigravity, Droid, Copilot, Junie or Qwen Code, that is decisive on its own.
• Remote projects over SSH, with tmux sessions that survive reconnects, and Emdash Cloud for ephemeral per-task compute. CmdBrief is local-first and single-machine.
• Issue-tracker ingestion from Linear, Jira, GitHub, Notion, Asana and more, and automations that schedule recurring agent runs.
• Pull requests and CI checks inside the app. CmdBrief shows you the diff; it does not manage the pull request.
• Multiple GitHub accounts, chosen per project.

What CmdBrief does that Emdash does not

Documented on CmdBrief’s site; not documented on the Emdash pages we read on 2026-09-29:

• Provider usage windows from several vendors side by side, with reset times — Claude Code 5-hour and weekly, Codex weekly, Grok CLI weekly credits, OpenCode Go rolling, weekly and monthly, Cursor CLI monthly pools. We found no usage or limit display in Emdash’s docs, so that row is a dash rather than a no. If this is the feature you came for, Claude Code usage limits explains what the windows actually are.
• A persistent workspace per product, not per task: repos, tasks with acceptance criteria, terminals, diffs, browser panes and saved layouts that outlive the branch that created them.
• Attention rolled up across products, so a blocked agent in a product you are not looking at cannot disappear behind another product’s tasks.
• A native macOS app with a hand-written VT emulator rather than an Electron shell. That is an engineering choice with real consequences for memory and text rendering, and it is also why CmdBrief is macOS-only.

CmdBrief does not ship a worktree per task, issue-tracker integration, automations, cloud execution or 35 providers. Do not expect it to.

Who should pick which

Choose Emdash if your day is one codebase and many parallel attempts at it, if you need Windows or Linux, if you want the app to be free and forkable, if your tickets live in Linear or Jira, or if your agent list runs past the six CmdBrief supervises. It is free and open source, and it ships several releases a month.

Choose CmdBrief if your day is “I operate five products.” The question a task list cannot answer is which product is blocked and which provider window is about to close, and that is the question CmdBrief is built around.

Skip CmdBrief if you are on Windows or Linux, on an Intel Mac, or on macOS before 26; if a free tier is a hard requirement; if a worktree for every task is the feature you are shopping for; or if you run agents on remote machines. If you are comparing the whole category rather than these two, start at the compare hub, and if the real problem is keeping sessions straight, read managing multiple Claude Code sessions on a Mac.
