Comparison

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.

What each one is

Windsurf is now called Devin Desktop; Cognition's FAQ says it is the same IDE with the same features. Its 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

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.

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.
