Frequently Asked Questions
Editor's Take
Budibase's built-in database is actually a bigger deal than most reviews mention. Half the internal tools I build are simple CRUD apps — "let the ops team manage this data." With Budibase, I don't need to provision a database first. With Retool, I always need an external data source. That said, for anything complex involving multiple APIs and databases, Retool's connector library is unbeatable.
