Claude Cowork alternatives: an agent desktop that runs any model
Claude Cowork brings Claude Code's agent architecture to knowledge work, on Claude plans only. OHarness is the same kind of agent — files, browser, connectors, schedules, subagents — on any model with your own key, but it is coding-first and runs on your machine, so it replaces part of Cowork rather than all of it.

Why people look for a Claude Cowork alternative
- Cowork needs a paid Claude plan — Pro, Max, Team or Enterprise — and Anthropic says it uses limits faster than chat.
- Wanting GPT, Gemini, DeepSeek or a local model for some tasks. Cowork's pages document Claude models only.
- Wanting the work, the files and the history to stay on your own machine and your own keys.
- Wanting to pay per token rather than per seat.
What to check
| Ask | Why it matters | OHarness |
|---|---|---|
| Which models can it use? | Agent work burns tokens; the model decides both quality and bill. | Any: Anthropic, OpenAI, Gemini, DeepSeek, 30+ providers, or local through Ollama or LM Studio. |
| Does it work on your files? | Most knowledge work starts in a folder. | Yes — the project folder it is opened on, and files or folders you attach. |
| Can it use a browser? | Half of real tasks are behind a login. | Yes — a built-in browser in the desktop app, or your own Chrome through the OHarness extension. |
| Which apps can it reach? | A task that cannot read your tickets or docs stops at the first question. | MCP connectors in one click (GitHub, Linear, Notion, Asana, Atlassian, Figma, Sentry, Stripe and more), any remote MCP server, and hosted app connectors such as Gmail. |
| Can it run on a schedule? | Recurring work is where an agent saves the most time. | Yes — cron schedules run by oharness schedule daemon. They run on your machine, so it has to be on. |
| What can it do without asking? | An agent acts with your accounts and files. | Five permission modes and allow/ask/deny rules; deny beats every mode. |
| What does it cost? | Seats and usage limits versus paying for what you use. | Free with your own key or a local model; an optional hosted plan bills usage in credits. |
What OHarness does not replace
- Cloud sessions. Cowork can run a task in a sandbox on Anthropic's servers with no device online; OHarness runs where you start it.
- Web and mobile. Cowork has web and iOS/Android surfaces in beta; OHarness's desktop app is macOS, with a browser UI served from your own machine.
- Computer use of other desktop applications. OHarness drives a browser, not arbitrary apps.
- Windows desktop. Cowork's desktop app runs on Windows; OHarness's desktop app does not yet (the CLI and browser UI do).
- A no-setup experience for non-technical teams. OHarness is built for people comfortable choosing a model and a key.

Common questions
What is Claude Cowork?
Anthropic's agent for knowledge work beyond coding, built on the same architecture as Claude Code. It launched in January 2026 and has been generally available on Claude Desktop for macOS and Windows since April 2026, on Pro, Max, Team and Enterprise plans.
Is there a Claude Cowork alternative that works with other models?
Yes. OHarness is a desktop and terminal agent with files, a browser, MCP connectors, schedules and subagents that runs on any model — Claude, GPT, Gemini, DeepSeek or a local model — with your own key. It is coding-first and runs on your machine, so it does not replace Cowork's cloud sessions or mobile apps.
Is there a free Claude Cowork alternative?
Cowork itself needs a paid Claude plan. OHarness is free to use with your own provider key, and costs nothing per token with a local model through Ollama or LM Studio. Eigent and OpenClaw are open source options.
Can I use Claude models in a Cowork alternative?
Yes. OHarness speaks the Anthropic API natively with your own key, so the same Claude models are available — alongside other vendors in the same session.
