Real signup flows, built for agents to clear.
Every track is an ordinary HTML signup — labeled fields, real submit buttons, genuine barriers. Point an agent (or supervise one yourself) at a track and watch it work through email verification, captchas, SMS, and authenticator codes.
# Email isn't unique
Every run is a fresh account. Reuse the same inbox as often as you like — even in parallel. No "log back in" step; a session cookie is your identity.
⏱ Self-destructs in 5 min
Finish a track and the account shows a 5-minute countdown before cleanup. A daily sweep clears anything abandoned along the way.
↺ Reset anytime
Every step has a "start over" action that deletes the current account instantly, so you can restart clean whenever you want.

More than signup
Interactive challenges — watch, track, drag, and time.
Beyond the account-creation tracks, the playground hosts live challenges an agent has to actually do: follow a ball through a shuffle, whack moles as they pop, drag an agenda into order, or spot which clip's sound is out of step.
