The
beta version of OnlyOffice Docs predecessor, Teamlab Document Editor, was introduced at

HTML5 that allows dynamic, scriptable
rendering of 2D shapes and
bitmap images.[4]

OOXML (DOCX, XLSX, PPTX) and DOCXF and OFORM. Other types of supported
formats (ODT, DOC,
RTF,
EPUB, MHT, HTML, HTM, ODS, XLS,
CSV, ODP, PPT, DOTX, XLTX, POTX, OTT, OTS, OTP, XML, XPS, DjVu and PDF-A) are processed with inner
conversion to DOCX, XLSX or PPTX if editing is possible.

API.[5] OnlyOffice Docs also supports integration via
WOPI.[6]
OnlyOffice DocSpace
OnlyOffice DocSpace is a cloud collaboration platform by OnlyOffice that combines online editors and a sharing environment based on rooms.[7]
Rooms of different types can be created:
In Collaboration rooms, users have access to all editing tools in the editors and can freely access any content.
In Public rooms, it is possible to invite users via external links to allow them to view files without registration, as well as embed the room contents into web interfaces.
In Custom rooms, following roles can be granted: room manager, power user, viewer, editor, commenter, reviewer, and form filler, with corresponding level of access to the files in the room.
Along with various access levels, DocSpace admins can adjust the security settings to control the login procedure and prevent data leaks, including such options as
2FA and
Single Sign-On, trusted mail domains and session lifetime, IP restriction, etc.[8]
