Sheetwrite / Documentation

Build web spreadsheets you still own.

Install the engine, choose an adapter, and build against explicit runtime, data, interaction, and delivery contracts.

Sheetwrite is a canvas spreadsheet engine with a Rust/WASM data core and first-party Vanilla, React, Vue, and Svelte adapters. The host application owns document state, persistence, collaboration, and product chrome.
