When an experienced team with production users first feels ‘we can’t keep duct-taping this,’ what exact failure makes them reach for Modelence instead of just adding another managed service or framework?

There are often two peak points, one at the beginning when a team has built a frontend, then is looking to add things like authentication and realizes they have to bring in a separate backend (setting things up and connecting is the main friction).

Later, the second realization is when you start needing deeper observability, and realize you have to bring in one more platform and set it up. Just adding another service is easy, but making them work seamlessly together is much harder. In this case the "failure" is that they realize they are spending way too much time to set things up to even see what's happening in their application in prod.
