# Helicon vs Cline

Cline is an agent that lives in the VS Code sidebar, brings its own provider configuration and shows approvals inside the editor. Helicon is a standalone desktop and web app for Meta's Muse Code CLI, built so the session list, approvals and cost survive independently of any editor window.

## At a glance

|  | Helicon | Cline |
| --- | --- | --- |
| Surface | Standalone app or browser | VS Code sidebar |
| Agent | Muse Code | Cline over your chosen provider |
| Billing | Existing Muse Code subscription | Your provider keys |
| Approvals | Queue, one to one with the protocol | Inline in the panel |
| Project scope | Every project on the machine | The open workspace |
| Cost view | Per thread, day and model | Per task token counters |
| License | MIT | Open source |

_Helicon compared with Cline._

## What each one is

Cline does a lot right: it shows you the plan, asks before it acts, and keeps the token counter visible. It is also tied to the editor window it runs in, and it expects you to bring provider credentials.

Helicon keeps the same honesty about approvals and cost but moves it out of the editor. The sidebar is projects and sessions across the whole machine, and the credentials question does not arise because Muse Code holds them.

## Where they actually differ

### No provider setup

There are no API keys to paste. If `muse login` works, Helicon works.

### Survives the editor

Close VS Code and your threads are still there, with their history, because they are indexed by the daemon, not by a workspace.

### Cross project triage

Threads are grouped by working directory, including isolated git worktrees, so parallel work has one place to be watched.

### Windows installer

Signed, auto updating, with native Muse Code support and WSL2 path translation as the fallback.

## Choose Cline if

- You want the agent inside VS Code with the editor's own diff flow.
- You want to choose the provider and model yourself.

## Choose Helicon if

- Your agent is Muse Code and your billing is its subscription.
- You want a session home outside the editor.
- You supervise more than one thread at a time.

## Can you use both?

Different agents, so they can coexist on the same repository. If you keep both, Helicon is the place you look when you want to know what is still running.

## Frequently asked questions

### Does Helicon ask before running commands?

Muse Code raises the approval and Helicon surfaces it. onRequest, promptUnmatched and denyUnmatched are mapped one to one, and allow all is behind an explicit opt in.

### Can I see token cost per task?

Yes. Helicon shows what each thread would have cost at published per token rates, plus daily and per model breakdowns. It is a meter reading on your subscription, not an invoice.

### Does Helicon need VS Code?

No. It is a standalone desktop app, and the same UI runs in a browser against a daemon.
