About Univer
Univer is an open-source SDK for building office applications inside your own product, providing spreadsheet, document and presentation experiences without a hosted app or fixed UI. It uses a plugin-first architecture with canvas-based rendering and a dedicated formula engine, and exposes one Facade API that works in the browser and on Node.js. Its headless runtime lets AI agents inspect, edit and verify Office content programmatically while humans review the same files. Developers can start quickly with presets or compose individual plugins for smaller bundles and deep integration.
