## ✨ What is Univer?
|
|
|
|
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.
|

## 🚀 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/`](./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.
|
|
|
|
## ⚡ 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.
|
|
|
|
<details open>
|
|
<summary><strong>Plugin Mode</strong></summary>
|
|
|
|
Plugin Mode gives you lower-level control over packages, style imports, locale merging, Facade API registration, and plugin configuration.

|
|
## 🧩 Preset Mode vs Plugin Mode
|
|
|
|
| Choose | When to use it | Start here |
|
|
| --- | --- | --- |
|
|
| **Plugin Mode** | You need strict control over packages, configured dependencies, lazy loading, or custom runtime composition. | This repository's [`examples/`](./examples) and [architecture guide](https://docs.univer.ai/guides/recipes/architecture/univer) |
|
|
| **Preset Mode** | You want a working Sheets, Docs, or Node setup with minimal configuration. | This repository's [`presets/`](./presets) and the [getting started guide](https://docs.univer.ai/guides/sheets/getting-started/installation) |
|
|
| **Headless Mode** | You need server-side workbook/document processing, formula calculation, or automation without UI. | [Headless Univer](https://docs.univer.ai/guides/sheets/getting-started/node) |
|
|
|
|
Keep the `@univerjs/*` SDK packages in the same coordinated Univer release line on the same version. Independently released packages, including `@univerjs/icons` and `@univerjs/icons-svg`, use the compatible versions declared by package manifests instead of the SDK version. If you use Univer Pro packages, keep `@univerjs-pro/*` aligned with the matching coordinated release line.
|
|
|
|
For API compatibility expectations, experimental APIs, internal APIs, and deprecation rules, see the [API Stability Policy](./docs/API_STABILITY.md).
|
|
|
|
## 🧭 Compatibility
|
|
|
|
- **Browser runtime**: Univer is compiled with a Chrome 88 target and aims to work on Edge `>=88`, Firefox `>=90`, Chrome `>=88`, Safari `>=14.1`, and Electron `>=12`.
|
|
- **Polyfills**: Univer relies on `Intl.Segmenter`. Add a polyfill such as `@formatjs/intl-segmenter` if your target browser or runtime does not provide it.
|
|
- **Build tools**: We recommend Vite, esbuild, or Webpack 5. If your build tool does not support the `exports` field in `package.json` (common in Webpack 4), you may need extra path mapping.
|
|
- **React**: Univer's view layer is built on React 18, supports React 18 and 19, and provides minimal compatibility support for React 16.9+ and 17.
|
|
- **Node.js runtime**: Headless Univer supports Node.js `>=18.17.0`. Developing this monorepo requires Node.js `>=22.18`.
|
|
|
|
## 🛠️ What You Can Build
|
|
|
|
| Area | Open-source capabilities | Univer Pro extensions |
|
|
| --- | --- | --- |
|
|
| **Sheets** | Workbooks, worksheets, ranges, selection, formulas, number formatting, filtering, sorting, data validation, conditional formatting, hyperlinks, comments, find and replace, notes, tables, drawing integration, and extensible UI plugins. | Real-time collaboration, edit history, import/export, printing, charts, pivot tables, sparklines, outlines, shapes, in-cell graphics, data connectors, server-side calculation, and performance-enhanced formula features. |
|
|
| **Docs** | Rich document model, editing UI, lists, hyperlinks, drawing integration, comments, quick insert, and shared document architecture. | Collaboration, import/export, printing, enhanced tables and lists, columns, callouts, code blocks, quotes, shapes, and remote comment resources. |
|
|
| **Slides** | Presentation data model and UI packages under active development. | Pro slide model and UI, slide import/export, chart and table model/UI plugins, and shared shape-editing infrastructure. |
|
|
| **Bases** | Build custom structured-data experiences on top of Univer's plugin, command, and model architecture. | Base database model, commands, formula integration, workbench UI, field editors, and render-engine views. |
|
|
| **Runtime** | Browser apps, Node.js headless usage, Web Worker/RPC patterns, multi-instance usage, and server-oriented automation. | Collaboration client/server packages, Node.js collaboration client, Pro server services, SSR, computing delegation, server-side calculation, and changeset replay tooling. |
|
|
| **Integrations** | React, Vue, Web Components, framework templates, theming, localization, and custom plugins. | Pro presets and enterprise deployment packages. |
|
|
|
|
Sheets are the most mature product surface today. Docs and Slides share Univer's architecture and continue to evolve in the same SDK.
|
|
|
|
## 🔓 Open Source and Pro
|
|
|
|
This repository contains Univer's open-source core and first-party OSS plugins. Univer Pro is developed separately as a commercial extension layer for advanced product surfaces, collaboration, server features, and enterprise integrations.
|
|
|
|
| Category | Open source | Univer Pro / commercial |
|
|
| --- | --- | --- |
|
|
| **Foundation** | Core SDK, plugin system, rendering engine, formula engine, Facade API, themes, i18n, and framework adapters. | Pro presets and enterprise deployment packages. |
|
|
| **Sheets** | Core spreadsheet editing, formulas, number formatting, filter/sort, data validation, conditional formatting, notes, tables, hyperlinks, comments, drawing, find and replace. | Collaboration, edit history, import/export, print, charts, pivot tables, sparklines, outlines, shapes, in-cell graphics, data connectors, range preprocessing, and enhanced formula engine features. |
|
|
| **Docs** | Document model and editor UI, lists, hyperlinks, comments, quick insert, and drawing integration. | Collaboration, import/export, print, enhanced tables/lists, columns, callouts, code blocks, quotes, shapes, and remote thread-comment resources. |
|
|
| **Slides** | OSS presentation model and UI packages. | Pro slide model/UI packages, slide import/export, charts, tables, and reusable shape editor UI. |
|
|
| **Bases** | Extensible plugin architecture for custom data-centric products. | Base database core model, commands, mutations, formula integration, workbench UI, field editors, and render-engine integration. |
|
|
| **Server and runtime** | Node.js headless runtime, RPC/Web Worker patterns, and server-oriented automation primitives. | Collaboration server, Node.js collaboration client, SSR services, computing delegation, server-side calculation, and collaboration changeset replay tooling. |
|
|
|
|
Pro features are documented in the [Univer Pro guide](https://docs.univer.ai/guides/pro). They are intentionally separated here so the OSS package surface is clear.
|
|
|
|
Boundary principles:
|
|
|
|
- OSS packages in this repository are intended to be useful on their own under the Apache-2.0 license. Univer Pro is optional and is not required to use the public OSS SDK APIs.
|
|
- Bugs, regressions, and security issues in OSS packages should be reported and fixed in the OSS repository, even when a related Pro feature exists.
|
|
- OSS documentation should not imply that Pro-only capabilities are available in public `@univerjs/*` packages. Pro-only APIs, packages, and deployment paths should be named explicitly.
|
|
- When an OSS feature has a Pro enhancement, the OSS behavior should remain documented independently so users can evaluate the open-source surface without reading commercial docs first.
|
