OK, this is really neat: - S3 is really cheap static storage for files. - DuckDB is a database that uses S3 for its storage. - WASM lets you run binary (non-JS) code in your browser. - DuckDB-Wasm allows you to run a database in your browser.

Put all of that together, and you get a website that queries S3 with no backend at all. Amazing.

Or use R2 instead. It’s even easier.
