open-claude-cowork

Open Source version of Claude Cowork with 500+ SaaS app integrations

Runs with mockssource: GitHubJavaScriptMITcommit 52335ef50fd0

JavaScript, MIT licensed. The project labels itself: aiagents, anthropic, anthropic claude, claude code, claude cowork, eclectron app, opencode and workflow automation.

open-claude-cowork runs, with stand-ins for the services it depends on. An Argusic agent installed it in 3 minutes and hit 3 errors and fixed every one without help on a clean machine with no GPU, and the whole session was recorded.

Backend server starts and responds on all API endpoints (health 200, chat 200 with SSE streaming, abort 200, validation errors 400); Electron desktop app launches and prints 'Electron app ready'

What the agent ended up with on a clean machine, in its own words. How this is measured

Measured by Argusic on a fresh machine every time. Every number links to its evidence. Argusic Score 92 of 100 (the mean of this project's run scores).

What was measured

From the run that decided this verdict. Every line is a recorded value, not an estimate.

Time lost to each failure while testing open-claude-cowork, drawn from the recorded run
Every bar is a failure the agent recorded, with the time it cost. Drawn from this run, not from anywhere else.

What went wrong, in the agent's own words

The agent's own words, worst first, never rewritten into advice.

What was not measured

The other half, so you can see exactly how far this evidence goes. A gap is printed as a gap and never filled in.

Peak GPU memory
this ran on a CPU machine, so there was no GPU to sample
Behaviour over a long run
each attempt uses the smallest documented settings and a fixed time budget, so this measures whether it runs, not how it holds up under load
Behaviour against real services
this run was verified against stand-in services only

How it was tested

One agent, one container, no human help. It installs the project the way its own documentation says to, runs it, and fixes what breaks. Everything below is recorded as it happened: the terminal session, the log and the exact commit. The full method.

Strengths and limits

Measured facts, not opinions. How this is written.

What went well

  • Installed in 3 minutes.
  • Recovered from all 3 errors without a human stepping in, which says the failures are documented well enough to solve.
  • Licensed MIT, as reported by its host.

What did not, or is not known

  • Only reached a running state against stand-in services, so nothing here proves it works against the real ones.
  • Measured once so far. A single attempt shows it can run, not that it runs reliably.

Also tested, in the same area

Every one of these was installed and run by Argusic on a clean machine. Nothing appears here that was not tested.

Questions

Does open-claude-cowork run?
open-claude-cowork runs, with mocks standing in for external services. Argusic installed and launched it on a clean machine in 3 minutes, hitting 3 errors on the way, and recorded the session.
How did Argusic test open-claude-cowork?
On a fresh, disposable machine, with every command recorded and the repository pinned at commit 52335ef50fd0. One attempt is recorded, and the full method is on the methodology page.
What did it cost to test open-claude-cowork?
The run that produced this verdict cost $0.07: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.
How long does open-claude-cowork take to install?
3 minutes in the run that decided this verdict, from a clean machine to a running state. That is one measured attempt, not an average.
Does open-claude-cowork need a GPU?
Not to start. Argusic reached a running state on a machine with no GPU.
What goes wrong when installing open-claude-cowork?
3 things broke in the recorded run, and 3 were fixed without human help. Each one, and the time it cost, is listed on this page.
Where is the evidence for open-claude-cowork?
The recorded run is on this page, each linking to its full log and terminal recording, stored with a sha256 fingerprint so it cannot be quietly altered.
