I originally wrote https://OnlineOrNot.com https://OnlineOrNot.com to be a snapshot testing tool for GraphQL servers back on 2017. Essentially it detected if your engineers suddenly broke or changed certain resolvers without updating the snapshots. I spent about two months building, then went around my professional network to try sell/market it. It turned out most folks using GraphQL didn't have this problem, because they had good test coverage, or wouldn't have engineers randomly change their GraphQL schema. I ended up rewriting it to be an Incident Management service (basically, an uptime checker for APIs, web apps, and websites, as well as a status page service), significantly easier to market now.
