--- title: "Helicon vs Warp for running Muse Code" url: https://helicon.sh/compare/warp description: "Warp is a modern terminal with agent features. Helicon is a purpose built GUI for the Muse Code CLI. What a better terminal gives you, and what it still cannot." updated: 2026-09-19 site: Helicon --- # Helicon vs Warp Warp makes the terminal better: blocks, history, its own agent. Running Muse Code inside it is still a terminal session. Helicon is a purpose built client that indexes projects and sessions, renders diffs inline, queues approvals and reports cost, because those come from the Muse Code protocol rather than from the shell. ## At a glance | | Helicon | Warp | | --- | --- | --- | | What it is | Muse Code protocol client | Terminal emulator with agent features | | Knows about Muse sessions | Yes, indexed and resumable | No, it sees text | | Diffs | Rendered inline in the thread | Whatever the CLI prints | | Approvals | Protocol level queue | A prompt in the block | | Cost | Per thread, day and model | Not available | | Multi repo triage | Sidebar grouped by directory | Tabs and panes | | Billing | Existing Muse Code subscription | Warp plan for its own agent | _Helicon compared with Warp._ ## What each one is Warp is a genuinely better terminal, and if the terminal is where you want to be then running `muse` inside it is a fine setup. Blocks make scrollback navigable and the command history is far better than a plain emulator. The ceiling is that a terminal sees characters. It cannot know that a particular run was a Muse Code session in a particular worktree, that a tool call is waiting on your approval, or what the turn would have cost. Helicon knows those things because it reads the Muse Code Session Protocol directly. ## Where they actually differ ### Structure, not text Helicon receives typed protocol events rather than parsing output, so sessions, turns, tool calls, approvals and usage are first class objects. ### Resumption Sessions are listed per project and resumable, including the ones you started in the terminal. ### Background work under control You can send a running tool call to the background, stop one, stop them all, cancel a workflow run, or skip and retry its agents. ### Free MIT licensed with no paid tier, running on the subscription you already have. ## Choose Warp if - You want one place for all shell work, Muse Code included. - You like Warp's own agent and are happy paying for it. ## Choose Helicon if - You want Muse Code sessions to be objects you can find again. - You want approvals and cost surfaced rather than printed. - You are running several threads and need to see which is blocked. ## Can you use both? Keep Warp as your terminal and open Helicon for the agent threads. Anything you start in Warp with `muse` shows up in Helicon's sidebar, so nothing is lost by switching between them. ## Frequently asked questions ### Can I still use the terminal after installing Helicon? Yes, and sessions you start there are discovered by the daemon and resumable in the app. ### Does Helicon include a terminal? Helicon shows the commands the agent runs and their output inside the thread. It is not a general purpose shell. ### Does it work on Windows terminals? Helicon runs Muse Code natively on Windows with PowerShell for shell commands, and uses Muse Code inside WSL2 with path translation when native is not installed. ## Related - [The muse terminal](https://helicon.sh/compare/muse-code-terminal): How a Muse Code GUI differs from the muse CLI terminal interface: session history, inline diffs, approvals and cost, side by side with what the TUI already does well. - [VS Code extensions](https://helicon.sh/compare/vs-code-extension): A standalone Muse Code desktop app compared with running the muse CLI inside VS Code: where an editor panel wins, where a separate session home wins, and how to run both. - [Zed with ACP](https://helicon.sh/compare/zed-acp): Running Muse Code inside Zed through an Agent Client Protocol bridge, compared with a standalone Muse Code desktop app. Editor native versus session native. - [JetBrains IDEs](https://helicon.sh/compare/jetbrains-acp): Muse Code inside IntelliJ, PyCharm, GoLand or WebStorm through an Agent Client Protocol plugin, compared with a standalone Muse Code desktop app. - [Claude Code desktop](https://helicon.sh/compare/claude-code-desktop): Two desktop apps for two different coding agents.
