Open-source, end to end.
Every project under Casual Office ships under Apache-2.0. You can self-host any of the demos via the published Docker images, fork the repos, and ship derivatives — commercial use included.
By repo
| Repo | License | Notes |
|---|---|---|
| CasualOffice/sheets | Apache-2.0 | Casual Sheets — the entire app + Docker bundle. |
| CasualOffice/docs | Apache-2.0 | Casual Editor — entire repo. The editor itself
(docx-editor/) is a fork of the MIT-licensed
eigenpal/docx-editor with the upstream MIT notice
preserved per attribution; our fork's own modifications and the Go
gateway (backend/) are Apache-2.0. The AGPL
agent-use package from the upstream has been removed. |
| CasualOffice/slides | Apache-2.0 | Casual Slides — the entire app, including the univer-revamp
fork patches. |
| CasualOffice/website | Apache-2.0 | This site. |
Apache-2.0 in plain English
You can use, copy, modify, and distribute the software — including in commercial products. Three obligations:
- Keep the copyright notice + the licence in any redistribution.
- State changes you made to the original code.
- If a
NOTICEfile exists, include the relevant lines.
There's a patent grant — and a patent-defensive termination clause that you should read if you're shipping derivative work commercially.
MIT in plain English
Use it however you want, including in proprietary or commercial products. Keep the copyright + the licence text in copies of the software. No warranty.
Trademark
"Casual Office", "Casual Sheets", "Casual Editor", and "Casual Desktop" are project names used by the authors. The licences cover the code, not the names — use a different name for forks that diverge significantly.
