Base44

Base44 positions itself as the app builder for people who don't want to hear about deployments or external services: database, user authentication, hosting and AI APIs are already built in. You describe the tool you need — an order manager, a small CRM, a booking system — and get a working application you can refine by chatting. The strength is precisely that all-in-one approach: what on other platforms means wiring services together comes pre-assembled here. In exchange, the credit system (for messages and integrations) forces you to watch consumption, and deeply customized projects will eventually hit platform limits. [Describe your own testing experience here: which business tool you built, how the data side went, what limitations you found.]
