The job here is narrow and unforgiving: build a small business web app where logged-in customers can view and update only their own records. Emergent and Mocha diverge on that job because the visible UI is the easy part; the real test is whether the tool can survive auth, data boundaries, schema changes, and repeated fixes without turning the app into a maintenance project.
That is exactly where generated-app platforms tend to fail in ways that matter. A polished dashboard is irrelevant if password recovery is brittle, a user query leaks the wrong rows, or a later prompt quietly rewrites working logic. For a client portal, the important question is not who makes prettier screens fastest, but who leaves fewer security and migration problems behind.
