Why your form data should live where you can query it, not just store it

Most developers default to form services or makeshift backends to handle landing page signups, but these tools separate data storage from data analysis. While capturing form submissions requires only a simple database insert — achievable without a full server — the real need is for a system that also supports querying and aggregation. Tools like form services excel at collecting submissions but leave users manually exporting CSVs when they need insights such as daily signups or referrer conversions. A more effective approach is storing submissions directly in a queryable database like Postgres, enabling analytical questions to be answered as easily as data is written. The core argument is that storage and interrogation should be unified, so that asking 'how many signups came from this campaign?' is as effortless as the original form capture.
