Abracadanames

A website for discovering first names through an interactive full-screen wall UI with infinite browsing, keeping most screen space on the core content.

The search field supports natural-language queries via a local multilingual interpretation engine with a cloud LLM fallback, backed by a custom database engine built in Rust and compiled to WASM for performance on Cloudflare Workers, without an external database service.
