BATS (Browser Agent Test Suite) — an open-source harness for stress-testing browser agents. You describe a scenario (“checkout process with credit card info in iframes + random popup”), and GPT-5 generates a realistic single-file test site and an agent prompt. Agents try to fulfill the task on the generated page with the instructions and the platform tracks the time they need, the type and amount of interactions, and if it fulfilled the task successfully. Additionally, the platform has an adversarial agent that tries to make the task more difficult for browser agents by e.g. injecting buttons with confusing labels.
