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.

S3 is doing quite a lot of sophisticated lifting to qualify as no backend at all.

But yeah - this is pretty neat. Easily seems like the future of static datasets should wind up in something like this. Just data, with some well chosen indices.

Still qualifies imo. Everything is static and on a CDN.

Lack of server/dynamic code qualifies as no backend.
