An agent buys two items
and checks the order.

A real run of Molar’s browser agent, step by step. It ran on October 24, 2026, on a developer machine, against Acme Shop: a test store we built with a test-mode payment page. It is not a customer app.

Goal
Sign in with the demo account, add the Packable Rain Jacket and the Merino Wool Socks, check out, pay with test card 4242 4242 4242 4242, then confirm the order and its total.
Result
Passed. “Order confirmed (AC-131604). Items: Merino Wool Socks and Packable Rain Jacket. Total: $147.00.”
Steps
8 steps in 39.7 seconds
Checks

    8. Order confirmed: AC-131604, total $147.00Next: Check the items and the total.

The numbered boxes are the page elements the agent could act on at each step. We blurred the test store’s demo credentials in step 1.

The test it exported.

After the run, Molar exported the steps as a Playwright test. Replayed without the agent, the test passed in 5.8 seconds. Run against a broken copy of the store that never confirms the order, it failed. We replaced the store address and the demo password with environment variables. Current exports read passwords from a secret the same way.
