What it is

Thinkfree Office combines an online word processor, spreadsheet and presentation tool for creating, viewing and editing documents. It supports DOC/DOCX, XLS/XLSX, PPT/PPTX and ODF files in ODT, ODS and ODP formats. The product supports collaborative editing, real-time collaboration and track changes, with a maximum document size of 300 MB. Organisations can deploy it on-premises, in a private cloud or through the Hosted API option; Docker and Kubernetes are supported. In a self-hosted setup, documents, version history and access logs remain on infrastructure managed by the customer. Hosted API adapters include Google Drive, Dropbox and Amazon S3, with WOPI support for platforms such as SharePoint and Nextcloud; saved files return to customer storage. White-labeling and interface customization include logos and colors. A Doc2PDF option converts Word, Excel and PowerPoint formats to PDF while preserving layout. A free 30-day trial is available; the MCC License costs $900 a year, billed based on active browser tabs with a 30-tab minimum.
