Shutdownify is shutting down
Truth is, this service never quite delivered on their promise.  When my last two startups closed shop, it took shutdownify over 3 days to process the first one, and the second was still a full two days to get up and running.  At that point I could have just put together a page myself.It didn't help that they rewrote their tech stack from Ruby to Node even as they were trying to find customers.  In the end, the user doesn't care what it's built with.
