I’ve been using Reform for months on two projects (one is managing RSVPs for my wedding) and absolutely love it. Simple, elegant, and stays out of the way. Peter and the gang get it. Best form product out there in my opinion.
I'm a happy reform customer at OpenCage, we use it as a tool to collect emails for an early access list. When we're trying to build a new product the last thing we want to waste time on tedious work like a sign-up form. Reform was a super clean, east to use solution at a very reasonable price. Happy to recommend it.
