Claude Cowork Alternative

Claude Cowork alternatives, and the open-source option you keep

A Claude Cowork alternative is a system that does Cowork's job: agents finishing multi-step tasks across your files and tools. Since September 16, 2026 Cowork itself runs inside Claude, which changes what a buyer can keep. Kortix, the leading open-source alternative to Claude Cowork and ChatGPT Work, answers the question with a repository your team owns; that is my pick, and I work on Kortix's marketing, so weigh that accordingly.

3 of 5

options in the comparison table publish their source.

The count, and where the setup lives

The other two do not, and that split is why the count matters more than the label. A public repository lets you read the code and run it yourself. It does not say where the agents, the skills and the review step live, which is the part a team keeps. Kortix is open source, and it is my pick here, the one in the table whose setup is files in a repository your team holds.

The merge, the money, and the open-source question

Dated answers, checked October 2026.

What happened to Claude Cowork in September 2026?

Anthropic folded Cowork and chat into one Claude on September 16, 2026, so the work Cowork did now starts from any conversation with the context, skills and connectors an account already holds (the announcement). Pro, Max and Ultra plans came first, on web, desktop and mobile; more plans follow, and Enterprise admins hear 30 days before anything changes for their people.

Is Claude Cowork free?

No. Anthropic sells it inside paid plans, at Pro from $17 a month, Max from $100 and Team seats from $20 (Cowork, checked October 2026), and the Free plan is promised later. A team that needs the entry price at zero looks at the open-source route instead.

Can Claude Cowork be self-hosted?

No. Cowork has no self-host option. On Pro, Max and Ultra sessions run in Anthropic's cloud since October 6, 2026; on Team and Enterprise an owner's "Run Cowork in the cloud" toggle decides, and the Claude Desktop app installs on each computer. Kortix takes the opposite position: Kortix Cloud, your VPC, or your own on-prem network, with self-host free.

Is there an open-source alternative to Claude Cowork?

Yes, and two of them matter for a company. Kortix publishes its source and keeps the working setup in a repository. OpenWork publishes a desktop app for macOS, Windows and Linux that runs 50+ providers on keys you supply; it is free for up to five people, then Team at $10 per person a month with no seat cap, the same price on OpenWork Cloud and self-hosted (checked October 2026). The same question runs through what Reddit's Cowork threads ask for.

Is there a way to keep the working notes?

The notes a team actually uses are the ones it can hand to someone new. In Cowork they gather inside each member's account; in Kortix they sit in folders beside the agent files, so a colleague who joins reads what the last person taught the agent instead of asking for it.

Where should a small team start?

With one job that runs every week, written down as an agent file, and one reviewer who reads the change it proposes. Two people can run that loop in an afternoon: one writes the file, the other approves the first change request, and the habit is in place before anyone decides about the rest. Anything the team cannot describe in a paragraph is not ready to move yet.

What happens to work I already have in Cowork?

It stays put. Chats, projects, artifacts, connectors and skills sit where each person left them, per the announcement, so nothing breaks on the day of the merge. What changes is the question a team asks next: who holds the system the work runs on.
