# ONLYOFFICE / Collabora

An office suite you host. ONLYOFFICE Docs is AGPL-3.0; Collabora Online is MPL — Word, Excel, PowerPoint, and Google Slides without the Microsoft 365 or Workspace seat.

**Replaces:** Google Slides / PowerPoint / Microsoft Excel / Microsoft Word

**Tier:** Medium

## Problem

Microsoft Word, Excel, and PowerPoint are the Microsoft 365 editors. Google Slides is the Workspace deck. You wanted .docx/.xlsx/.pptx on hardware you control. ONLYOFFICE Document Server is AGPL-3.0 (ONLYOFFICE/DocumentServer). Collabora Online is MPL (already named on /replace/google-docs). CryptPad is AGPL-3.0 if the job is an end-to-end-encrypted pad, not an OOXML suite. This is not Microsoft 365 Copilot, Excel's every Power Query SKU, or Google Slides' add-on store. A live sheet with relations stays on /replace/google-sheets (Grist). Files-and-suite Nextcloud stays on /replace/google-drive.

## Stack

- [ONLYOFFICE Docs](https://www.onlyoffice.com) — AGPL-3.0 document server for .docx/.xlsx/.pptx
- [Collabora Online](https://www.collaboraonline.com) — MPL LibreOffice-based editor Nextcloud Office can wrap
- [CryptPad](https://cryptpad.org) — AGPL-3.0 end-to-end-encrypted pads if OOXML is not the job

## Estimated SaaS cost saved

| You stop paying | Typical / year | Self-host instead |
|---|---:|---|
| Microsoft 365 / Google Workspace editors (small team) | $1,200 | ONLYOFFICE or Collabora + a volume |

**About $1,200 / year** on a small team, before you count lock-in.

## AGENT_PROMPT

```
Replace Microsoft Word, Excel, PowerPoint, or Google Slides with ONLYOFFICE Docs (preferred) or Collabora Online.

- Nextcloud if you also want Drive-shaped files — /stacks/nextcloud-files. Live sheets stay on /stacks/grist-sheets.
- Write AGENT_PROMPT.md.
```

## FAQ

### ONLYOFFICE or Collabora?

ONLYOFFICE if you want the AGPL OOXML suite. Collabora if you want the MPL LibreOffice-based editor (the Nextcloud Office wrap). /compare/onlyoffice-vs-collabora.

### Is this Google Sheets?

A .xlsx file, yes. A live multiplayer sheet with relations is Grist — /replace/google-sheets.

### Why not just Nextcloud?

Nextcloud is the Drive suite that can wrap these editors — /replace/google-drive. This page is the editor itself.
