A link you can send
The demo leaves your laptop. You send the link. A teammate, a customer, or a friend clicks it and sees the thing you just built.
Use cases
Prototypes
Put the prototype on a live link. Someone else can open it today, on their own phone, while you are somewhere else.
A few rows, if the demo needs them
A waitlist, a vote, a note left on the prototype. A Table keeps those rows with the page.
Small enough to put away
When the demo is over, the link can come down. The prototype stayed a prototype the whole time.
