Proto was in Y Combinator's Fall 2026 batch, at prototypes.fun. Y Combinator's directory lists the company as active. We don't check YC companies' websites.
We don't know from this record whether the product still operates, what it charged, or why its status is what it is. Across the whole register, 22% of launches whose status we could settle are gone.
What the check recorded: YC lists the company as active (YC F26).

Show HN and Product Hunt entries are judged by asking the domain whether it still answers: gone means it no longer resolves, refuses the connection, serves a parking page, or says plainly that it has shut down. An HTTP error is not counted as gone — a server that answers 404 is one somebody still pays for. Y Combinator entries use the status YC itself publishes (active, inactive, acquired or public), which is why only those can say acquired or public. Search the whole register.
