Helicon vs Warp

At a glance

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.
