A page changed. Now what?
VisualPing tells you something on a page is different. webwhen tells you when your specific question has an answer. Two different jobs.
Pixel changes are not the same as answers.
VisualPing watches the visual surface of a webpage. When something on the page is different from last time, it sends you a screenshot. That works when you know exactly which region you care about and you can see the change with your eyes.
webwhen does a different job. You describe a condition in plain English, like 'tell me when the PS5 is back in stock at Best Buy', and the agent figures out how to check, what counts as evidence, and when the condition is actually met. No region selectors. No false positives from sidebar reflows.
VisualPing is great if you already know the answer is on the page and you want to be told when the pixels move. webwhen is built for the messier case: the answer might appear anywhere, and you want to be told only when it actually appears.
VisualPing watches pixels. webwhen waits for answers. If your question can be expressed in English, you don't need either selectors or screenshots — just the question.
Try webwhen instead.
Free while in beta. No setup, no configuration. The agent decides everything.
