Lovable App Not Working? What Breaks Between the Demo and Production
A DEV Community article describes an analysis of 264 public reports of Lovable apps breaking, collected from Reddit, Trustpilot, GitHub, and Hacker News, with each report sorted by its cause. The author writes that the biggest groups were logins and database connections (37 reports), Lovable itself being down (33), and apps that could not be found on Google (32). Close behind were 31 reports about data that was exposed or at risk, which the author calls the one problem a working app can hide completely. The author also recounts a bug in one of their own products, where any logged-in user could see other customers' private data because the app checked that a user was logged in but not that the requested data belonged to that user. Nothing crashed and nobody complained, which the author says is why nobody noticed. The article frames this as the gap between a demo and production: a demo only has to work for the builder, on their laptop, while they watch, whereas production has to work for every user, on every network, when Lovable has a bad day, when credits run out, and when someone tries to open data that is not theirs. The author states the article lists the causes in the order they would check them, each with the fix from Lovable's own documentation, and notes they build on Supabase.
The post's report tally points to authentication, database connections, and exposed data as recurring failure points when Lovable apps move from demo to production.
