Office tools, one runtime
Univer
Not one tool — the whole runtime. Sheets, docs, slides, and canvases live in one .univer file, composing and embedding freely, with humans and agents working side by side.
- Every block in one place — a slide holds a live sheet, a doc cites its source, a canvas lays it all out
- Data stays synchronized across every block — sources change, references update
- Humans and agents co-edit in the same file, every change traceable
Core Features
Full details in the feature list.
One Runtime for Every Office Tool
Spreadsheets, docs, slides, canvases, relational tables, and more — on a single runtime. Data stays connected and traceable: a doc references a sheet; the source changes, everything synchronizes.
Human–Agent Co-Editing
Humans and agents edit the same file at the same time. Review, refine, or directly modify agent-produced work — at any point in the workflow.
Multi-Agent Workflows on Worktrees
Run multiple agents on the same file simultaneously — each on its own isolated worktree. Humans review and merge every contribution.
Git-Style Version History
Every change is tracked and reviewable. Restore any version, merge with control.
Agent Self-Verification
Agents set their own validation conditions, test their output, and iterate until requirements are met — before handing it back.
High-Fidelity Import & Export
High-fidelity import and export for XLSX, DOCX, PPTX, CSV, TSV, PDF, and more. See the full format list under Capabilities.
Self-Hosted by Design
Deploy on your own infrastructure. No third-party accounts, no data leaving your environment.
Embed Anywhere
White-label, no watermark. Customizable themes, feature trimming, i18n, and open NPM packages.
Excel-Grade Performance
A formula engine with 500+ formulas and execution — computation speed on par with Excel, capacity up to 10M cells. Changeset sync — collaborators get the diff, not the file. Less to transfer, faster to sync.

Univer Runtime
Compose & embed
- Spreadsheets, docs, slides, relational tables, canvases, and more — every piece works like a block, composing and embedding freely
- Put a sheet in a doc, a doc in a slide — any file embeds any other
- Container pages aren't type-locked — a worksheet can be a doc or a slide page
- One storage and computation layer underneath — a sheet embedded in a doc still runs its formulas
Collaboration
- Real-time multiplayer editing
- Humans and agents edit the same file simultaneously or in turns
- Every change traceable to its author — human or agent
Unified storage & computation
- Synchronized blocks across file types
- Cross-file formula references — sources change, results recalculate
- Update the source — every reference stays synchronized
- Changeset sync — collaborators get the diff, not the file. Less to transfer, faster to sync
Deployment & data sovereignty
- No third-party accounts needed
- Local deployment and offline editing
- Full self-host — server and viewer; data stays private and never touches third-party servers
Versioning & human control
- Full version history, restore any version
- Agent changes are structured and reviewable
- Approve, merge, or restore after agent edits
- View any version in the Viewer (roadmap)
- Side-by-side version comparison (roadmap)
Agent workflows
- Any agent with the CLI can read, understand, create, and modify every file type
- Agent self-verification — set conditions, test, fix, then deliver
- Multiple agents in parallel, on isolated Worktree branches
- Agents work across files — read here, write there, stay in sync
- Shell-native — compose with awk, grep, sed, jq, and Python
Integration & extensibility
- Webhooks and events — file changes trigger downstream systems
- Custom buttons and UI components via Facade API
- Theme customization via Facade API
- Feature trimming — read-only mode, hidden tools
- Multi-language interface (i18n)
- Embed in your product, no watermark
- Open-source NPM packages, maintained
