Detailed Review
Calligra Suite is the office and graphics suite developed by the KDE community, the successor to KOffice. Calligra Words is the word processor, Sheets the spreadsheet and Stage the presentation program, all installed locally with no account, no cloud component and nothing transmitted, which makes it one of the lightest data protection assessments in this category. Version 4.0, released in August 2024, moved the whole suite to Qt6 and KF6 with a revised interface, and tagged releases have continued since.
There is no company behind it. Calligra is built by volunteers inside KDE, whose legal body KDE e.V. is a registered non-profit association with its postal address in Berlin, Germany, and the code is free software under LGPL 2+ and GPL.
It costs nothing and has no paid tier. ODF is its native format; Words also opens Microsoft Word files (.doc and .docx) and saves them back to ODF, and Stage uses OpenDocument natively, so exchanging files with Microsoft Office users goes through conversion rather than a promise of exact DOCX, XLSX or PPTX round-tripping.
The trade-offs are practical. Calligra targets Linux and is installed from a distribution's software store or Flatpak; its download page says Windows support is still being worked on, and there is no macOS build listed. It has no real-time collaboration, no hosted version and no vendor support, so it suits an individual or a Linux workstation fleet rather than a team that needs shared editing or guaranteed Microsoft fidelity.
What Calligra Suite does well
- Free software under LGPL 2+ and GPL, with no paid tier
- Words, Sheets and Stage cover documents, spreadsheets and presentations
- Runs entirely locally, so no data leaves the device
- Maintained by the KDE community, with the suite moved to Qt6/KF6 in 4.0
- Opens Word .doc and .docx files and saves to ODF
Where Calligra Suite falls short
- Linux-focused: Windows support is still being worked on, no macOS build
- No real-time collaboration and no hosted version
- ODF-first, so Microsoft fidelity is conversion rather than exact round-tripping
- Volunteer project with no vendor support or SLA
Standout feature. The KDE office suite: free software from the KDE community, built natively for the Linux desktop and entirely local.
