A local test run lives in a terminal. A screenshot lives in chat. Bring the cases, the evidence, and the review into one workspace.

A few useful details
Your coding agent writes the tests. Clanker Test teaches it how, gives it the resources it needs, and gives you a place to review the results. Ask your agent to validate the work it just did.
Create an account and a workspace. A plugin and agent API come next. For now you can sign in, create workspaces, and invite people.
Local runs live in a terminal on one machine. Clanker Test is a shared place to publish results, inspect evidence, and show that the agent built what you asked for.
Later: disposable email inboxes, phone numbers for OTP, secrets, and other resources so agents can automate real product flows. Those APIs are not in this first cut.
Yes. Scheduled and automated runs come after the first product cut. This version is the logged-in workspace foundation.
