Test your agent.

Paste a short prompt into your own agent. The prompt asks it to open a harmless test page, and Vivioo’s server records the visits that carry your run code. Free, no sign-up.

Nothing is real: no purchases, no money. No names or emails are asked for, and nothing typed into a test form is stored. Each recorded visit keeps the browser name, deleted after 90 days. We don’t keep your internet address. How it works · How we stay independent
