The DocumentServer description names collaborative online editors for text, spreadsheets, presentations, forms and PDF, “fully compatible with Office Open XML” (.docx, .xlsx, .pptx) and real-time co-editing. DesktopEditors is the desktop pack of that family. Those are upstream labels. We have not independently tested OOXML fidelity.
Listed on Excel alternatives, PowerPoint alternatives, and Microsoft Word alternatives. Mature local suite without a collab server: LibreOffice Calc / Impress. New Rust editors: GridCraft, DeckCraft, WordCraft.
FAQ
Is ONLYOFFICE free and open source?
The GitHub projects we opened (ONLYOFFICE/DocumentServer and ONLYOFFICE/DesktopEditors) ship AGPL-3.0 LICENSE files (checked 2026-10-20). Hosted or enterprise SKUs on the vendor site are separate. Not legal advice.
Docs vs Desktop Editors?
DocumentServer (“ONLYOFFICE Docs”) is the collaborative online suite (7,032 stars, last push 2026-10-16, release v10.0.0 on 2026-10-12). DesktopEditors is the desktop pack (5,602 stars, v10.0.0 on 2026-10-13) for Windows, Linux, and macOS. Same AGPL-3.0 family.
Excel, Word, or PowerPoint?
The GitHub description names viewers/editors for texts, spreadsheets, presentations, forms and PDF, compatible with OOXML (.docx, .xlsx, .pptx) and real-time co-editing. We list it on all three hubs. No quality ranking against Microsoft 365 or LibreOffice.
