Comparison
Helicon vs Cline
Cline is an agent that runs as an extension in VS Code, JetBrains IDEs and other editors, and also ships a CLI and a desktop app. It 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.

What each one is
Cline does a lot right: it shows you the plan, asks before it acts, and keeps the token counter visible. In the IDE it is tied to the editor window it runs in, and it bills through your provider keys or through Cline's own usage billing.
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
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.
Helicon is one Muse Code GUI of several, and that page lists the rest. Helicon is free and MIT licensed, and you can try Helicon in your browser on sample data before you install anything.
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.
