Claude Cowork alternatives in 2026: seven open-source options, and what you give up

Claude Cowork hands real work to Claude on your desktop, but it needs a paid Claude plan and runs on Claude models. If you want something open source, free to start, or able to use other models, these seven desktop apps are the realistic options. One honest note first: on some plans Cowork can keep a task running in Anthropic's cloud after you close your laptop. Every app on this list, Orkas included, needs your computer to stay on.

Why people look elsewhere

Four reasons, four different answers

“I don't want another subscription”

Cowork is included only in paid Claude plans (Pro, Max, Team and Enterprise). Every app here is open source and free to download.

“I want other models”

Cowork runs on Claude. The apps below let you connect other model providers with your own API key, and some can also use local models.

“I already use coding CLIs”

If Claude Code, Codex or OpenCode already do your repository work, a desktop app that drives them can fit better than adding a second agent.

“I want to read the code”

With open source you can check what an agent is allowed to do before it touches your files.

This list is published by Orkas, and Orkas is one of the entries; its row is marked. Licences and platforms were checked on each project's GitHub page, and Cowork's details in Anthropic's help center, on October 8, 2026.

The list

Seven alternatives, grouped by what you want instead

Built as a Cowork replacement

  1. 01Eigent

    Eigent describes itself as “the open source Cowork desktop”. It is Apache-2.0, has desktop builds for macOS, Windows and Linux, and splits a task across a workforce of agents that run on the model keys you bring.

  2. 02OpenWork

    OpenWork calls itself “the open-source alternative to Claude Cowork” and is built on OpenCode, so it inherits OpenCode's wide model choice. It has desktop builds for macOS, Windows and Linux.

    Most of the code is MIT, but one enterprise directory is under a separate licence.

  3. 03Open Cowork

    Open Cowork is an MIT desktop app for Windows and macOS. It installs Claude Code, MCP tools and Skills in one step, runs them in a sandbox, and connects to Feishu and Slack.

A desktop window for the agents you already run

  1. 04AionUi

    AionUi is Apache-2.0, for macOS, Windows and Linux. It puts OpenClaw, Hermes, Claude Code, Codex, OpenCode and more than 20 other CLI agents in one desktop window, with custom assistants you can team up.

    Project on GitHub →

One general agent or a chat studio instead of a workspace

  1. 05Goose

    Goose is an Apache-2.0 agent with a desktop app and a CLI for macOS, Windows and Linux, and it works with the model you choose. It installs, runs, edits and tests on your machine, which makes it closer to one capable agent than to a team.

    Project on GitHub →
  2. 06Cherry Studio

    Cherry Studio is a desktop studio for macOS, Windows and Linux with chat, autonomous agents and more than 300 ready-made assistants across most major model providers. It is the best fit if what you miss most is a good multi-model chat window.

    It is AGPL-3.0, which adds obligations if you modify it and offer it to others as a service.

    Project on GitHub →

A team of agents, plus the CLIs you keep

  1. 07OrkasOurs

    Orkas is MIT, with installers for macOS and Windows. A Commander turns your goal into a plan and hands parts of it to specialist agents for research, documents, slides, images and video. It can also run Claude Code, Codex, OpenCode, OpenClaw and Hermes as members of the team. Use your own API key or Orkas-hosted models; new accounts get 500 free credits.

    What it does not do: the installer needs an account, tasks stop when the app is closed, and it does not give each agent its own git worktree.

Platforms are the desktop builds each project publishes on GitHub. Cowork's plans and platforms come from Anthropic's help center.

Running Claude Cowork on Windows

Cowork does run on Windows, but it has more requirements than a normal app, and they are the most common reason it won't start. As of October 8, 2026, Anthropic's documentation lists:

  • Windows 10 build 19041 (version 2004) or later, or Windows 11, on x64 or Arm64.
  • The .msix installer. The older .exe installer gives you Claude Desktop without Cowork.
  • Working hardware virtualization and the Windows feature “Virtual Machine Platform”, because Cowork runs its tasks inside a virtual machine. Anthropic offers a free readiness check that tells you whether your PC is ready.
  • On work computers, a Group Policy that controls “Log on as a service” can stop Cowork's virtual machine from starting.

Anthropic has said Windows 11 Home is supported, but users on both Home and Pro keep reporting that Cowork won't start, with errors such as “Missing HCS services”. The usual first fix is to turn on Virtual Machine Platform and restart fully.

Orkas installs as a regular desktop app on Windows and doesn't run tasks in a virtual machine, so it doesn't need Virtual Machine Platform or hardware virtualization turned on.

Try a team instead of a single agent

Orkas is free to download for macOS and Windows. Start with 500 free credits on Orkas-hosted models, or connect your own API key, or the Claude Code, Codex and OpenCode CLIs you already use.

FAQ

Common questions

Is there a free alternative to Claude Cowork?

Yes. Every app on this list is open source and free to download, while Cowork itself needs a paid Claude plan. With Orkas you can start on the 500 free credits new accounts get, or use your own API key.

Is there an open-source Claude Cowork alternative for Windows?

Yes. All seven apps on this list publish Windows builds. Cowork also runs on Windows 10 and 11, but only on paid Claude plans, and it needs hardware virtualization and the Virtual Machine Platform feature. Orkas doesn't use a virtual machine, so it doesn't need either.

Why won't Claude Cowork start on my Windows PC?

Cowork runs its tasks in a virtual machine. It needs Windows 10 version 2004 or later, the .msix installer, hardware virtualization and the Virtual Machine Platform feature. An error such as “Missing HCS services” usually means that feature is off; turn it on and restart. Anthropic's readiness check shows what is missing.

Can a Cowork alternative still use Claude models?

Most of them can, through your own Anthropic API key, which Anthropic bills per use rather than through a Claude subscription. Orkas can also run the Claude Code CLI as one of its agents.

What does Cowork do that these apps don't?

On some plans Cowork can run a task in Anthropic's cloud and keep going after you close your laptop, and it is also available on the web and in the mobile apps. The apps here, Orkas included, run on your own computer and stop when it does.
