What is ONLYOFFICE?

ONLYOFFICE is an open-source office suite with online editors for text documents, spreadsheets, presentations, fillable forms and PDFs, built for real-time co-editing. The editors come inside ONLYOFFICE DocSpace, a room-based collaboration platform offered in the cloud or on-premises, or can be connected to platforms such as Nextcloud, Box and Moodle. Free desktop and mobile apps cover offline work.

ONLYOFFICE has a free plan. Paid plans start at $20 per admin / month for the DocSpace Business cloud plan. See every plan

Good for

  • Organizations that want to host their own office suite
  • Teams on Nextcloud, Box, Moodle or Odoo that need document editing there
  • Sharing files with clients in separate rooms with their own permissions
  • People who want free desktop editors that work offline

Worth knowing

  • The free DocSpace Startup plan stops at 3 admins, 12 rooms and 2 GB, and lacks SAML SSO, LDAP, branding, a custom domain and the audit trail.
  • DocSpace Business costs $20 per admin a month; the pricing page shows it as reduced from $30 and gives no end date for that price.
  • Docs Enterprise is licensed by simultaneous connections, from $1,500 for a 1-year, 50-connection, on-premises license with Basic support.
  • A 1-year Docs Enterprise license stops working when it ends; a lifetime license keeps running but loses free updates after its support period.
