CmdBrief vs JetBrains Air: ADE or Mac workspace?

The short answer

Pick JetBrains Air when you already live in JetBrains tooling, or when you need what a platform brings: runs isolated in a Git worktree or a Docker container, an agent-neutral protocol underneath so you are not tied to one vendor, a browser surface as well as a desktop one, Windows and Linux, and — if you are buying for an organisation — policy, permissions, audit and AI cost control over the whole thing.

Pick CmdBrief when you are one person running several products on agent CLIs you already subscribe to, and the thing you cannot see is the portfolio: which product is blocked, which agent is waiting on you, and how much of this week’s allowance each vendor has left. Apple silicon, macOS 26+, local-first, one paid plan.

They coexist without friction, because Air can drive agents through Air Gateway from the command line and CmdBrief runs those same CLIs in panes. If what you actually want is an editor-shaped answer rather than either of these, CmdBrief vs Cursor-as-workspace is the closer comparison.

The data behind this comparison

What JetBrains Air is for

From the product page, the quickstart, the supported agents and credits and usage documentation, the launch post and the Air Teams post, read on 2026-09-29:

• Agents you already use, plus a protocol. Claude Agent, OpenAI Codex, Gemini CLI and Junie are documented as supported agents, each on your own provider account or a JetBrains AI subscription, and you can add “any ACP-compatible agent installed on your machine.” Air Gateway exists to “bring terminal agents like Claude Code and Codex into Air” from the command line. The product page also names Copilot and OpenCode, and the IDE plugin runs CLI agents “in a full terminal inside an editor tab.”
• Four run environments per task. Local Workspace, where “the agent runs on your machine and writes directly to your working copy”; Git Worktree, where “the agent works in a separate Git worktree on a dedicated branch, so your main working copy stays untouched”; Docker, “an isolated container with its own filesystem, useful for running untrusted code”; and Cloud, which “runs in a remote cloud environment” and pushes the result to a task branch. You pick per task.
• Review as a first-class step. Task Changes opens the diff from the session in unified or side-by-side view, with comments on specific lines sent back as follow-up instructions, plus “Review with <agent>” — a separate review task run by a fresh agent session, optionally a different agent, whose comments you accept or reject.
• Several projects in one window. “Workspaces share one window, so you can open as many projects as you need and switch between them in the Tasks tool,” each keeping its agent sessions, Git state and tools, with unread updates, changed files and outgoing commits tracked per project. Each task shows its own state in the Tasks tool, including “Input required” when it needs you.
• A terminal and a web preview in the window. A Terminal tool with sessions in tabs, and a Web preview pane that opens for web projects when the server starts.
• Credits, and a context meter. A counter shows JetBrains AI credit usage and the date the monthly limit resets, and each task shows how much of its context window it has used. For a provider you connect directly, the docs say to check usage “in that provider’s own app or console.”
• Plan and permission modes, project instructions read from CLAUDE.md and AGENTS.md, MCP servers, skills and commands, and Air Context’s semantic indexing so agents “start with an understanding of your project instead of scanning the entire codebase”.
• Four surfaces. A desktop app for macOS, Linux and Windows, still shipped as preview builds; a plugin for JetBrains IDEs, now labelled a public preview; a web version, “currently available only to organizations”; and the CLI gateway. Cloud runs are “already available for some customers in JetBrains IDEs and the browser” and are rolling out gradually, and the Air in IDEs page says a JetBrains AI subscription “is currently required for cloud runs.”
• Teams and governance. Air Teams runs shared projects in dedicated cloud environments with VM size, internet access and secrets under your control, plus automations for code review, release notes and fixes. Air Governance sets model and agent permissions per organisation, team or individual and offers “flexible limits for teams and individual contributors” over AI spend. Air Teams is “already available to JetBrains business customers, with plans to expand access to individual customers later.”

That is a lot of product, and it is being built by a vendor with 26 years of tooling behind it. Nothing on this page should be read as suggesting otherwise.

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.

A platform, or a workspace

The launch post is the clearest statement of the difference, and it is JetBrains’ own: Air “cannot be just another agent or development environment. It must connect products for individual work, team coordination, organizational control, context, and process automation.” That is a system, and systems are bought by organisations — which is why Air Teams and Air Governance exist, and why the words in that post are policy, visibility, auditability, cost management and accountability.

CmdBrief is bought by one person for one Mac. There is no team tier, no governance surface, no cloud, no audit log, and no admin console. The shape it optimises for is a founder with five products and six CLI subscriptions, where the expensive mistake is not an ungoverned model choice but a product that sat blocked for two days because its agent was waiting behind another product’s tab.

Both do keep several projects in one window, and Air is explicit about tracking unread updates, changed files and outgoing commits across them. Be fair about that: it is a real cross-project view. What we did not find documented is a per-product home that restores pinned tasks, a pane layout and browser context, so that row reads “partial”, not “no”. On provider allowances the docs are explicit: “JetBrains Air tracks usage for JetBrains AI only,” so the cross-vendor usage row is a “no”.

Where they overlap

More than you would guess from the size difference. Both are agent-neutral by design and say so. Both let you bring your own provider subscription or API key rather than reselling model usage. Both run agents locally against your real working copy. Both show a diff beside the agent that made it. Both keep several projects open at once. Both put a terminal and a browser or web preview pane in the same window. Both read the project instruction files agents already use, CLAUDE.md and AGENTS.md included.

Air goes further into platform territory: Docker and worktree run environments, cloud execution, a browser surface, IDE integration, semantic project indexing, automations, teams and governance, Windows and Linux. CmdBrief does not claim any of those.

CmdBrief goes further into one narrow place: multi-vendor provider usage windows with reset times, and a persistent per-product home. Air’s cost story is JetBrains AI credits with a monthly reset, plus spend governance for an organisation — “control the cost … with flexible limits for teams and individual contributors” — which is a different answer to a different question than “how many hours of my Claude weekly window are left”; for a provider you connect directly, Air’s docs send you to that provider’s own app. In the GUI comparison, Superset and Nimbalyst document Claude and Codex usage side by side as of 2026-09-29 (Nimbalyst adds Gemini); CmdBrief’s difference is more vendors on one screen — Claude Code, Codex, Grok CLI, OpenCode Go and Cursor CLI — rolled up across products.

One asymmetry worth stating: Air supports Claude Agent on an Anthropic account, and brings Claude Code in through Air Gateway or ACP. CmdBrief supervises the Claude Code CLI itself, on the subscription you already have, which is a narrower but more direct relationship. Neither is better in the abstract.

What JetBrains Air does that CmdBrief does not

• Windows and Linux, and a browser surface, and a JetBrains IDE plugin. CmdBrief is Apple silicon on macOS 26+ only.
• Docker and Git-worktree run environments chosen per task, with Apply Locally and Check Out Branch Locally to bring the result back. CmdBrief creates worktrees only for the code builders a lead agent starts, and no containers.
• “Review with <agent>” — a second agent reviewing the first agent’s diff, with comments you accept before they go back. CmdBrief shows the diff and leaves the review to you.
• Air Teams and Air Governance: shared cloud projects, automations, organisation-wide model and agent permissions, audit and AI spend limits. CmdBrief is single-operator with no admin surface.
• Cloud execution, rolling out to IDE and browser customers, so work is not tied to one machine.
• Semantic project indexing (Air Context) so agents do not re-scan the repository, and JetBrains code intelligence for verifying what the agent produced.
• Agents CmdBrief does not supervise, including Junie, Gemini CLI and anything else that speaks ACP.
• The app itself is free to download. CmdBrief has one paid plan and no free trial.

What CmdBrief does that JetBrains Air does not

Documented on CmdBrief’s site; not documented on the JetBrains Air 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. Air tracks JetBrains AI credits only and sends you to each provider’s own app for the rest. Claude Code usage limits explains what those windows are.
• Grok CLI, Kimi CLI and Cursor CLI as supervised agents, with session resume across all six from local metadata. Air’s documented agent list is Claude Agent, Codex, Gemini CLI and Junie, its product page adds Copilot and OpenCode, and further agents come in over ACP.
• A persistent workspace per product: repos, tasks with acceptance criteria, terminals, diffs, browser panes and saved layouts, restored together.
• Attention rolled up across products, with the same working / needs-action / completed / failed states for every supervised CLI.
• A shipped, generally available product rather than a public preview, whose desktop app and IDE plugin still ship as preview builds and whose team tier opens to business customers first.

CmdBrief does not ship containers, cloud runs, governance or an IDE. Do not expect it to.

A note on pricing

This page carries no JetBrains Air price because JetBrains publishes none for Air itself: the desktop app and the IDE plugin are free. What costs money is the agents. They run on a JetBrains AI subscription (AI Pro or AI Ultimate, whose store prices we read on 2026-09-29 are in the data above), on a provider account you already pay for such as Claude Pro, Max or Team, or on your own API key, and JetBrains AI credits are “billed at public API rates”. Cloud tasks and automations always spend JetBrains AI credits, Docker tasks “can’t use a Claude subscription”, and the Air in IDEs page offers Junie’s Lite model free until the end of the year.

So compare the shape rather than the total. Air’s model spreads cost across a JetBrains subscription, your existing provider plans, and credits you top up; CmdBrief is one flat subscription on top of the provider plans you already hold, and it resells none of them. Which is cheaper depends on how much agent work you run and on which plans, so price it yourself.

Who should pick which

Choose JetBrains Air if JetBrains IDEs are where your team works, if you need Windows or Linux, if agent runs have to be isolated in a container, if someone has to be able to answer “which models can which team use, and what did it cost”, or if you want a platform that is being built out rather than a finished single-purpose app.

Choose CmdBrief if you are one operator with several products and several CLI subscriptions, on an Apple silicon Mac, and the missing information is portfolio-shaped: what needs you, in which product, and how much allowance is left.

Skip CmdBrief if you are not on a Mac, if you need team or governance controls, if a free app is a hard requirement, or if your agents are Junie and Gemini CLI rather than the six CmdBrief supervises. For the nearest free, cross-platform, worktree-first alternative read CmdBrief vs Emdash; for the Claude-only end of the range read CmdBrief vs opcode; and the rest are on the compare hub.
