None of the suggested alternatives so far are the same as Sunrise's meet feature-- including vyte, Microsoft Invite, Google's Appointment Slots, or calendly.

Meet allows you (the requester) to set the times available for meeting and send a signup page to a single respondent.

It's not about group meetings, or about "office hours" that anyone can sign up for. The use case is surprisingly broad: a small window of availability for a single meeting.
