# Helicon vs Windsurf

Windsurf is an agentic AI editor with its own models and subscription, built to be the place you write code. Helicon is a free MIT client for Meta's Muse Code CLI that gives your existing subscription a window: projects, sessions, diffs, approvals and cost, beside whatever editor you already use.

## At a glance

|  | Helicon | Windsurf |
| --- | --- | --- |
| Category | Client for the Muse Code CLI | AI first code editor |
| Agent | Muse Code, yours | Windsurf's own agent |
| Billing | Existing Muse Code subscription | Windsurf plan |
| License | MIT | Proprietary |
| Editor replacement | No | Yes |
| Cross repo session list | Yes, grouped by directory | Per window |
| Runs on a remote daemon | Yes, same UI in a browser | Remote development features |

_Helicon compared with Windsurf._

## What each one is

Windsurf's pitch is flow: an editor that keeps context as the agent works across your codebase, with its own model routing behind a plan you buy.

Helicon's pitch is narrower and cheaper. You already have Muse Code. Helicon is the window that makes several Muse Code threads manageable, keeps their history, shows the diffs inline, and puts every approval in front of you.

## Where they actually differ

### Nothing new to pay for

Helicon has no plan. It is MIT licensed and free, and it uses the Muse Code subscription you already have through your own `muse login`.

### No editor migration

Adopting Helicon does not change where you write code, which keybindings you know or which extensions you rely on.

### Local first and inspectable

One daemon on your machine, one `muse serve` per workspace, state in local SQLite, source in one public repository.

### Windows is handled

Signed installer with auto update, native Muse Code on Windows, WSL2 with two way path translation when that is what you run.

## Choose Windsurf if

- You want an editor and an agent from the same vendor.
- You want model routing handled for you.

## Choose Helicon if

- You hold a Muse Code subscription and want more than a terminal.
- You keep your editor and only want the agent to have a home.
- You want open source with no credential storage.
- You want cross project triage across repos and worktrees.

## Can you use both?

There is no conflict. Windsurf is an editor purchase, Helicon is a free client for an agent you already pay for.

## Frequently asked questions

### Does Helicon have autocomplete?

No. Helicon is a client for an agent, not an editor. Completion stays with your editor.

### Can I use Windsurf and Helicon together?

Yes. They are separate products with separate billing and do not interfere with each other.

### What does Helicon cost?

Nothing. MIT licensed, no paid tier, no second bill on top of Muse Code.
