Thinkfree Office in Nextcloud for Data Sovereignty
In our previous article, Data Sovereignty Fuels Google workspace Alternatives, we explored the growing movement across Europe to find alternatives to Microsoft 365 and Google Workspace. At the heart of this shift lies a mounting concern over data sovereignty. Following the enforcement of GDPR, laws like the U.S. CLOUD Act have raised fears that foreign legislation could indirectly control data stored within European jurisdictions. This has prompted governments, public institutions, and enterprises in sensitive industries to rethink their cloud strategies altogether.
So what solutions are actually being adopted? In this article, we take a closer look at one of the most realistic combinations currently in use across Europe: Nextcloud paired with Thinkfree Office. We’ll explore why this combination is gaining traction from both a technical and regulatory perspective.
Why Look Beyond Open-Source Office Solutions?
Nextcloud is a collaboration platform that allows organizations to store and manage data entirely on self-hosted infrastructure, eliminating the need to rely on third-party cloud services. Bundled with open-source editors like Collabora Online, it enables document editing without license fees and supports teams seeking data sovereignty and cost-efficiency. However, users have noted that it can fall short in real-world use, particularly when handling professional-grade documents.:
-
Rendering Performance: Delays in loading complex documents, real-time collaboration lag, and mobile rendering issues due to browser limitations.
-
Low-Resolution Image Output: Images in documents or presentations often appear pixelated or lose clarity.
-
Inaccurate Document Formatting: MS Office files suffer from formatting discrepancies, compromising document fidelity.
-
Connection and Integration Challenges: Frequent errors like “Failed to load” disrupt document access.
These are not just minor technical issues. They can have a noticeable impact on everyday workflows. Rendering delays can slow down collaboration and reduce overall efficiency. Blurry images or quality loss during PDF export may affect clarity and make documents seem less professional. Formatting inconsistencies in MS Office files can cause challenges in fields like law or finance, where accuracy is essential. Connection problems, often caused by backend misconfigurations, may disrupt access at important moments. Collabora reflects the values of open-source software, but due to these limitations, some users remain cautious about relying on it as a full replacement for Microsoft Office in professional settings.
OnlyOffice has often been noted as a practical alternative, particularly in response to concerns about rendering quality and compatibility. However, its adoption in public institutions remains limited, partly due to sensitivities around the developer’s geopolitical background. In sectors where legal neutrality and institutional credibility are essential, caution tends to prevail.
