Health-check recipes for the failures that bite no-code apps.
Generic uptime monitoring tells you the homepage returns 200. It does not tell you a Lovable publish serves a blank screen, a Bubble checkout webhook went to /version-test, a Supabase magic-link email never arrives, or the nightly job exits clean without doing anything. These recipes collect those scenario-specific checks — copy one, set up the monitors, and know what to look at first when something breaks.
Lovable published app health
