Univer is an open-source SDK for creating office applications inside your own product. It gives you the building blocks for spreadsheet, document, and presentation experiences without forcing you into a hosted app or a fixed UI. Use Univer when you need to: Embed spreadsheet or document editing into a SaaS product, internal tool, BI workflow, or AI application. Run workbook/document processing on the server with the same architecture used in the browser. Compose only the features you need through plugins or start quickly with presets. Extend behavior through custom plugins, commands, services, UI components, and Facade APIs. Univer is not a spreadsheet file viewer only. It is a framework for building your own productivity surface. Across the Univer product family , Office tools share a runtime for storage and computation. Content can be composed and embedded across tools, with linked data and references updating together. People and AI agents can work in the same files. See the capability matrix for product coverage and Open Source and Pro for this repository's scope. Built with Univer Office SDK These open-source projects are built with Univer Office SDK: Project Description Univer Workspace An Office workspace for people and AI agents, with shared editing and review of agent changes. Univer Office for DeepSeek Harness An Office plugin for DeepSeek Harness with connected content, validation, and isolated worktrees for agent collaboration. Univer CLI A local command-line workspace for agents to create, edit, inspect, and deliver Office content. Univer Office for WorkBuddy A local Office integration for WorkBuddy with MCP previews and draft review. Development preview. Univer Office for OpenClaw Tools for creating, reviewing, and delivering Office content in OpenClaw. Each project documents its own setup and SDK licensing requirements. 🌟 Highlights ⚡ Built for large surfaces Canvas-based rendering and a dedicated formula engine keep complex workbooks responsive. 🧩 Plugin-shaped by default Compose, replace, lazy-load, or extend capabilities without taking the whole stack. 🤖 Headless for AI infrastructure Run workbook and document logic in Node.js to power agents, automation, and server-side workflows. 🛠️ Product-ready SDK Framework adapters, Facade APIs, presets, and headless runtime fit real integration paths. 🌗 Dark-mode ready UI components and the rendering engine both adapt to light and dark themes. 🔌 Unified Facade API One consistent API surface for workbooks, ranges, formulas, and documents across browser and Node.js. 🚀 Why Univer? Isomorphic by design : run UI apps in browsers and headless processing in Node.js. Plugin-first architecture : every capability is delivered as a composable plugin, so features can be added, removed, replaced, or lazy-loaded. Preset mode for fast integration : use the curated plugin collections in presets/ when you want a working app quickly. Plugin mode for full control : manually compose packages when you need custom loading, smaller bundles, or deep integration. Facade API : work with workbooks, worksheets, ranges, documents, formulas, commands, and events through a higher-level API. Canvas rendering engine : support large editable document surfaces with a rendering layer shared across document types. Extensible UI : integrate with React, Vue, Web Components, and framework-specific application shells. 🤖 Office Workflows for AI Agents Univer's AI and collaboration capabilities connect agent operations with interactive editing and human review: Programmatic editing : agents inspect and modify Office content through structured APIs. Output verification : agents check results through content inspection, rendered screenshots, and layout diagnostics. Worktree collaboration : agents work in isolated drafts, then people review their changes and decide what to merge. See the AI SDK documentation for integration details. Live editing, shared revisions, and Worktree workflows require the corresponding Web SDK and collaboration capabilities; package availability and licensing vary by feature. ⚡ Quick Start Use Plugin Mode for complete product coverage and precise composition. For supported Sheets, Docs, and Node profiles, Preset Mode provides a shorter curated setup. Plugin Mode Plugin Mode gives you lower-level control over packages, style imports, locale merging, Facade API registration, and plugin configuration. pnpm add @univerjs/core @univerjs/design @univerjs/docs @univerjs/docs-ui @univerjs/engine-formula @univerjs/engine-render @univerjs/sheets @univerjs/sheets-formula @univerjs/sheets-formula-ui @univerjs/sheets-numfmt @univerjs/sheets-numfmt-ui @univerjs/sheets-ui @univerjs/ui import { LocaleType , mergeLocales , Univer } from '@univerjs/core' import { FUniver } from '@univerjs/core/facade' import DesignEnUS from '@univerjs/design/locale/en-US' import { UniverDocsPlugin } from '@univerjs/docs' import { UniverDocsUIPlugin } from '@univerjs/docs-ui' import DocsUIEnUS from '@univerjs/docs-ui/locale/en-US' import { UniverFormulaEnginePlugin } from '@univerjs/engine-formula' import { UniverRenderEnginePlugin } from '@univerjs/engine-render' import { UniverSheetsPlugin } from '@univerjs/sheets' import SheetsEnUS from '@univerjs/sheets/locale/en-US' import { UniverSheetsFormulaPlugin } from '@univerjs/sheets-formula' import SheetsFormulaEnUS from '@univerjs/sheets-formula/locale/en-US' import { UniverSheetsFormulaUIPlugin } from '@univerjs/sheets-formula-ui' import SheetsFormulaUIEnUS from '@univerjs/sheets-formula-ui/locale/en-US' import { UniverSheetsNumfmtPlugin } from '@univerjs/sheets-numfmt' import { UniverSheetsNumfmtUIPlugin } from '@univerjs/sheets-numfmt-ui' import SheetsNumfmtUIEnUS from '@univerjs/sheets-numfmt-ui/locale/en-US' import { UniverSheetsUIPlugin } from '@univerjs/sheets-ui' import SheetsUIEnUS from '@univerjs/sheets-ui/locale/en-US' import { UniverUIPlugin } from '@univerjs/ui' import UIEnUS from '@univerjs/ui/locale/en-US' import '@univerjs/design/lib/index.css' import '@univerjs/ui/lib/index.css' import '@univerjs/docs-ui/lib/index.css' import '@univerjs/sheets-ui/lib/index.css' import '@univerjs/sheets-formula-ui/lib/index.css' import '@univerjs/sheets-numfmt-ui/lib/index.css' import '@univerjs/engine-formula/facade' import '@univerjs/ui/facade' import '@univerjs/sheets/facade' import '@univerjs/sheets-ui/facade' import '@univerjs/sheets-formula/facade' import '@univerjs/sheets-numfmt/facade' const univer = new Univer ( { locale : LocaleType .
