Before joining, my partner had spent almost $2M for a CRUD app using GraphQL, and Lambda on Postgres. It couldn't handle more than a couple of small users and cost about $1,000 per user per month.
CRUD was the wrong shape for heavy reporting, so I rebuilt it: Every user gets their own BigQuery instance, exported to Parquet, consumed by DuckDB WASM in the browser so dashboards are instant.
We achieved Feature parity in about four months, then got back to the roadmap.
active users
- Old stack. CRUD app, GraphQL, Lambda, Postgres. About $1,000 per user per month.
- New stack. BigQuery, Parquet, DuckDB WASM. $1,000 per month plus $1 to $5 per user, plotted at $5.
