Welcome to the official GitHub repository for ONLYOFFICE Apps!
ONLYOFFICE Apps are modular building blocks that extend ONLYOFFICE Docs: AI agents, Forms, Rooms, and Files. Each app solves an everyday problem, and you turn on only what you need. Apps and editors work as one flexible system: install the editors, extend them with apps, and integrate the package into your own solution. No technical skills required, so you can get going in minutes. Starting with version 4.0, released alongside ONLYOFFICE Docs 10.0, ONLYOFFICE Apps replace DocSpace.
This repository contains the source code for the backend and frontend components of ONLYOFFICE Apps.
- From one fixed space to modular apps: AI agents, Forms, Rooms, and Files are now separate apps you can mix and match. In the cloud, all apps are activated by default; on server builds, a quick installation gets you set up. Existing DocSpace accounts move to the new structure automatically, with no action needed.
- AI chat in every app: work with rooms, files, and forms faster, with workspace automation, quick file generation, intelligent search, and a personal knowledge base.
- Bigger knowledge base for AI agents: now supports TXT, MD, JSON, CSV, Word, Excel, and PowerPoint formats (including macro-enabled files and templates), and PDF.
- Forms app: start from auto-generated forms or ready-made templates, collect responses in a database or spreadsheet, and let AI analyze the results.
- Files app: one home for all your documents, with quick search and filters, folders and tags, and precise access settings.
- AI in the cloud, ready in one click: no API keys, no AI subscription, and a choice of leading models. Note: custom API keys set up in the cloud before this release are no longer used; you can keep using them in the free Desktop Editors.
- Works with ONLYOFFICE Docs 10.0: AI tools in every editor, a smarter PDF Editor, faster spreadsheets, and 40+ security fixes.

AI Chat across all apps. Work faster with rooms, files, and forms: open the chat as a side panel in any room, folder, or document. Your conversations follow you across the workspace.
- Create ready-to-use files: ask for a report, a fillable PDF form, a presentation, or an image, and get the file right in your workspace.
- Work with files and images: attach documents, scans, receipts, or screenshots and ask AI to extract, summarize, or analyze them.
- Search the web: get up-to-date answers with clickable sources.
AI agents for your team. Create custom agents in their own dedicated section for a wide range of tasks. Give an agent instructions and a knowledge base built from your own documents, then invite colleagues with different roles. Call any agent from the AI Chat in any room or folder.
Extend AI with MCP. With the built-in ONLYOFFICE MCP Server, AI can create rooms, organize files, and manage users right from the chat. Connect external MCP servers too, and choose how much freedom AI gets with tool approval modes.
AI in the cloud. Start in one click, with no AI provider sign-up or API keys. There is no AI subscription: you pay only for what you use from your workspace Wallet. Choose from a hand-picked selection of models from OpenAI, Anthropic, Google, xAI, DeepSeek, and more, and assign a different model to each task, such as chat, summarization, translation, OCR, or image generation.
💡 Want your own API keys or local models? Connect your cloud to the free ONLYOFFICE Desktop Editors and use any AI provider, or run models locally with Ollama or LM Studio.

- Never start from a blank page: pick an auto-generated form or a ready-made template, tweak it, and share. You can also ask AI to build a fillable PDF form from a short description.
- Responses land neatly in a database or spreadsheet, all organized for you.
- AI analyzes the results and helps you understand every answer.
Rooms are built for working together, with a room type for every situation. Each room comes with preset permissions and roles.
- Collaboration rooms: Invite users to co-author and edit documents in real-time.
- Public rooms: Share documents for view-only access with external users via a public link.
- Custom rooms: Define your own access permissions, whether it's for review, commenting, or form filling.
- Virtual data rooms: Automatically index and track all content. You can enable watermarks, set file lifetime, restrict downloading and copying.
AI helps you find, manage, and keep everything tidy.
- Store and manage all your documents in a single spot.
- Find what you need in seconds with quick search and filters.
- Organize with folders and tags, and decide exactly who sees what.
- No more digging through endless folders: AI helps you track down the file you need.

The standalone deployment runs all ONLYOFFICE Apps services in one container, alongside optional containers for the editors, MySQL, and OpenSearch. It is the default topology of the installation script for every edition: Community, Enterprise, and Developer. If you need to scale out horizontally, use the microservices or stack topology instead. Check the instructions ➡️
Note: This creates a development/testing environment not suitable for production use. For production deployment, see How can I get ONLYOFFICE Apps?
