SQLite in the Browser
A local-first boilerplate powered by SQLite WASM + OPFS. Data persists on-device. Queries run in microseconds.

Sub-millisecond reads
SQLite runs entirely inside a Web Worker via WASM. All I/O is synchronous on OPFS — the fastest storage primitive available in browsers.
Persistent, private storage
OPFS stores data directly on-device. It survives page reloads and works offline. Your data never leaves the browser.
Framework-agnostic primitive
Import src/db.ts into any modern stack — React, Vue,
Svelte, Astro — and you're done.
