Compare · Coshell vs Windsurf

Windsurf is a single-player AI editor. Coshell is a shared live session for the whole team.

Windsurf, now Devin Desktop, is a strong AI editor for one developer on their own machine. Coshell is a different thing: the shared live session in the cloud that your whole team and one agent work in together.

Windsurf is an excellent editor
A polished, VS Code-based AI IDE whose Cascade agent reasons across your whole codebase and makes multi-file edits. As a local AI editor for one developer, it is genuinely strong.
Now Devin Desktop
Cognition, the maker of Devin, acquired Windsurf and in 2026 rebranded the editor to Devin Desktop. The editor people search for as Windsurf is the same single-player IDE.
Coshell is a different kind
Not a local editor. A shared live session in the cloud that a whole team and one agent work in at the same time.

Windsurf gives each developer their own AI editor on their own machine.Coshell puts the whole team in one shared live session with one agent.

One agent, one live session, the whole team prompting it together.

What Coshell adds for a team.

The difference is not a better editor. It is the layer between the people: one shared live session, one shared agent, in the cloud. Every line below is running in production today.

01 · single-player vs shared

One shared live session, not an editor per person

Windsurf runs on each developer's machine, with each person prompting their own agent. Coshell puts several people in one shared live session in the cloud, prompting one agent on one running filesystem and terminal, and watching the same work land together.

02 · free to self-host, no seats

Adding teammates costs nothing extra

Windsurf is priced per seat once you have a team. Coshell is free to self-host, no seats: run a drive on your own machine, up to five teammates in your org, unmetered, and no per-seat charge.

03 · your keys, your models

Bring your own keys across 70+ models

Coshell runs 70+ models on your own provider keys, scoped per drive, on every plan. Usage is billed by your provider, not marked up by us. Admins choose the allowed set per drive.

04 · nothing to install

Browser or terminal, no desktop app

Windsurf is a desktop app you install per machine. Coshell runs in any browser and from the CLI, with an integrated localhost browser preview in the session, so a teammate joins from any device with nothing to set up.

Windsurf is a best-in-class local editor. Coshell is the shared session a team works in.

Use both

Keep your editor. Add the shared session.

Most engineers keep a local editor for solo work and join a shared Coshell drive when the work is shared. Coshell runs your own repo on your own model keys, pushes to your real git, and is priced free to self-host, no seats, so the whole team can be in one session without a per-head bill.

Built on OpenCode

Coshell is built on OpenCode, the open agent engine, and adds the shared session your whole team works in together.

Coshell vs Windsurf, answered

Is Windsurf the same as Devin Desktop now?

Yes. Cognition, the maker of Devin, acquired Windsurf in late 2025 and rebranded the editor to Devin Desktop in 2026. It is the same single-player AI IDE most people still search for as Windsurf. Devin itself, the autonomous async agent, is a separate product. Coshell compares to the editor here, and to the autonomous agent on the Coshell vs Devin page.

Does Windsurf have real-time multiplayer like Coshell?

Not in the sense Coshell means. Windsurf is single-player per developer: each person runs their own local editor and their own agent. It adds team-account features like central billing and admin, and views for coordinating multiple AI agent sessions, but several humans do not share one live coding session. Coshell is built around exactly that: many people in one shared live session prompting one agent at once.

Can a team use Coshell and Windsurf together?

Yes. Many engineers keep a local editor like Windsurf for solo work and drop into a shared Coshell drive when the work is shared: pairing, debugging together, onboarding, live review. Coshell is the shared session your team works in, not another editor to switch to.

Can I bring my own models and keep my code in-house?

Yes. Coshell runs 70+ models on your own keys, scoped per drive, and a drive pushes to your real git repositories as ordinary git. Self-host it on your own machine and your code never leaves it, free; theEnterprise tier adds org-wide on-prem and SSO.

Get your team in the same session.

Keep your local editor for solo work. When the work is shared, open a drive and put the whole team in one live session with one agent.
