The useful answer is not a best-terminal ranking.
The job here is a technical founder running several products on agent CLIs: Claude Code, Codex, Grok CLI, Kimi CLI, OpenCode, Cursor CLI. The bottleneck is not which emulator draws glyphs fastest. It is whether the next decision is attached to the product it belongs to, or scattered across tabs, sessions, and editors.
CmdBrief is the local Mac workspace that pins agents, tasks, terminals, diffs, and browser context to each product so you can see what is working, blocked, or waiting. It is not a Warp, Ghostty, or iTerm replacement, and it is not an IDE. Warp, Ghostty, and iTerm are terminals (Warp is now also an agentic development environment). Cursor, Claude Desktop, and Conductor are the closest “one window” alternatives, and they still do different jobs.
Provider terms and product behavior can change. Confirm plan, pricing, model, and permission details in the official documentation linked on each page.

No scores. A cell that looks empty is not a loss; it is a different job.
The data behind this comparison
Each comparison below is backed by a data file rather than by prose. Versions, release dates and licences come from the vendors’ own feeds and refresh on a schedule; pricing, platform support and capability verdicts are read by a person and carry their own date.

Pick a capability heading to read that column across every tool.
- Agent CLIs — Third-party agent CLIs run as a first-class surface, not just as a process in a shell.
- Agent status — Working / needs-input / done states for agent work, visible without opening each session.
- Usage windows — Provider usage windows or limits shown inside the app.
- Usage across vendors — Usage windows from more than one agent vendor, side by side.
- Per-product workspace — A persistent home per product that restores repos, panes, tasks, and context.
- Diff review — A first-class view for reviewing the changes an agent made.
- Browser pane — A browser or preview pane inside the same window.
- Cloud execution — An option to run agents on the vendor’s infrastructure rather than your machine.
- Windows / Linux — Desktop builds beyond macOS.
- Open source — The client itself is published under an open-source licence.
The short map
Terminals. Ghostty and iTerm are terminal emulators. CmdBrief includes a real terminal (a hand-written VT emulator), but the product is the supervision layer around multiple products and agent CLIs. Replacing Ghostty or iTerm is not the point.
Warp. Official pages call Warp an open agentic development environment, not “just a GPU terminal.” It runs Warp Agent plus third-party CLIs (Claude Code, Codex, OpenCode, Gemini CLI, and others), has native code editing, and hands work to cloud agents. That overlap is real. The remaining difference is the founder job: Warp is the ADE you type in; CmdBrief is the local Mac workspace that pins context to each product and rolls up attention plus usage across several products and several CLIs.
Conductor. Melty Labs’ Mac app creates a git worktree and branch per workspace, runs Claude Code, Codex, Cursor, or OpenCode inside it, and carries the result through a diff review with comments back to the agent, a Checks tab, a pull request, and an archive. There is a free local tier and a paid cloud tier with team multiplayer. Its unit is the branch; CmdBrief’s is the product. If one repository with many parallel attempts is your day, read CmdBrief vs Conductor and expect a split verdict.
Emdash and opcode. Both are free and open source, and they sit at opposite ends of the range. Emdash is General Action’s Apache-2.0 desktop app: a git worktree per task, 35 agent CLIs on its Providers page, issue-tracker ingestion, remote machines over SSH, and builds for macOS, Windows and Linux, with several releases a month. opcode, formerly Claudia, is an AGPL GUI for Claude Code alone, with checkpoints and Claude API cost analytics; its last release is dated 2025-08-31, which CmdBrief vs opcode sets out with the commit log rather than a verdict. Start at CmdBrief vs Emdash if free and cross-platform is the requirement.
JetBrains Air. A different weight class: an agentic development environment in public preview, with a desktop app, an IDE plugin in public preview, a browser surface and a CLI gateway, driving Claude Agent, Codex, Gemini CLI, Junie, GitHub Copilot, OpenCode and any ACP agent, in a local workspace, a git worktree or a Docker container. On 2026-09-22 JetBrains expanded it into Air, Air Teams and Air Governance. If you need policy, audit and AI spend control over a team, read CmdBrief vs JetBrains Air — and note that Air itself has no price: the app and plugin are free, and agents run on your own provider account or a JetBrains AI subscription.
Cursor and Claude Desktop. These are the closest “one window” alternatives. Cursor is editor-plus-agents (and cloud agents) for software you build in Cursor. Claude Desktop is Anthropic’s GUI for Claude Code: sessions sidebar, a worktree option per session, diff review, terminal, file editor, browser pane. CmdBrief does not replace either. It creates worktrees only for a lead agent’s crew builders, not per session (pair your own sessions with claude --worktree). It does supervise Claude Code, Codex, Grok CLI, Kimi CLI, OpenCode, and Cursor CLI in persistent product workspaces, with usage windows side by side where the provider reports them.
Constraints that are real
CmdBrief is Apple silicon, macOS 26+, local-first Rust, generally available since 2026-08-06. One paid plan: CmdBrief Pro, display prices €29.99/mo or €299.90/yr, 14-day money-back, no free trial. It does not resell agent provider plans.
If you run one product on one vendor, start with that vendor’s own app. The Claude Code GUI for Mac guide is explicit: the official desktop app is the better deal for Claude-only work.
Questions
Is CmdBrief a Warp / Ghostty / iTerm replacement?
No. Those are terminals (Warp is also an ADE). CmdBrief includes a terminal so agent CLIs have somewhere honest to run. The product is the workspace that keeps agents, tasks, diffs, and browser context attached to each product.
Is CmdBrief an IDE?
No. Keep the editor you trust. A mixed setup is valid: Cursor or your editor for direct code work, terminal agents for bounded delegation, CmdBrief for the founder-side supervision of several products.
Which comparison should I read first?
If you already have a terminal you like, start with Warp, Ghostty, or iTerm + tmux + Claude Code so you do not replace the wrong layer. If you already work in one window, start with Cursor or Claude Desktop. If you came looking for an alternative to a specific app, go straight to Conductor, Emdash, opcode, or JetBrains Air.
Which of these is free?
Ghostty and iTerm2 are free and open source, and so are Emdash (Apache-2.0) and opcode (AGPL-3.0). Conductor has a free local tier, Warp and Cursor have free tiers, the JetBrains Air app is free to download with agents billed separately, and Claude Desktop is included with a paid Claude plan. CmdBrief is the outlier: one paid plan, no free tier, with a 14-day money-back guarantee instead.
Do I need CmdBrief if I only run Claude Code?
Usually not. Use Anthropic’s desktop app (included with Pro, Max, Team, and Enterprise) or claude agents in the CLI. Third-party apps earn a place when you run other CLIs alongside Claude, or when you supervise several products and need attention and usage rolled up across them.
