Building prototypes locally is always free and unlimited. You can make as many prototypes as you want, with as many screens as you want, forever, without an account.
Plans only come in when you publish a prototype as a link.

Everyone starts on Free. Your first publish quietly starts a 7-day trial. There is no card, no countdown, no nag. Publish as much as you like during those 7 days. Upgrade any time at prototo.app/pricing or from your account .
How viewing works
People you share with run your prototype natively with the free Prototo app on their iPhone. Viewing is free and unlimited for them, and it never counts against your plan. Every link you publish stays live forever, even if you never upgrade.
When the trial ends
After the 7 days, publishing new links asks you to upgrade. Everything you already published keeps working:
Your 7-day Publish trial has ended. Upgrade to Plus ($8/mo or $80/yr)
to keep publishing.
