🌋 The Embedded Database for the Modern Web
This is the monorepo for MoltenDb Web — a high-performance Rust engine compiled to WASM with persistent storage via OPFS.
Use it as a full-featured embedded database or as a persistent state manager — your app's data survives page reloads, browser crashes, and unexpected connection loss automatically.
