Whether in meetings, workshops or everyday project work – collaborative visual work is becoming increasingly important. Teams that work remotely or in hybrid setups need tools to quickly structure thoughts and capture results. A digital whiteboard embedded directly into your own cloud infrastructure offers a decisive advantage: all ideas are created where the rest of your data already resides – protected, centralized and always accessible.
The Whiteboard Server for Nextcloud combines the flexibility of an interactive canvas with the security of a self-hosted solution. Unlike SaaS services such as Miro, Mural or Conceptboard, your content never leaves your infrastructure. This makes the Whiteboard Server particularly attractive for companies, public authorities and organizations with high requirements for data protection and information security.
A collaborative whiteboard unfolds its benefits in virtually every work context. The following examples show how different target groups use the Whiteboard Server:
Data protection is not an optional feature but a fundamental prerequisite for professional collaboration. The Whiteboard Server is operated exclusively on servers in Germany, located in TÜV-audited, ISO 27001 certified data centers. This means the solution meets the strict requirements of the European General Data Protection Regulation (GDPR).
Unlike US-based cloud services, your data is not subject to access by foreign authorities (no CLOUD Act, no Patriot Act). You retain complete control at all times:
This makes the Whiteboard Server particularly suitable for public authorities, municipalities, healthcare facilities, law firms and enterprises that process sensitive information and must comply with regulatory requirements.
Numerous whiteboard solutions rely on a centralized SaaS model with servers outside the EU. The Whiteboard Server for Nextcloud takes a fundamentally different approach:
| Whiteboard Server | SaaS providers (Miro, Mural) | |
|---|---|---|
| Data location | Germany / EU | Usually USA |
| GDPR-compliant | Fully | Limited |
| Data control | Fully with the customer | With the provider |
| Integration | Nextcloud-native | Separate platform |
| Cost | From €9.99/month | From approx. $8–16/user/month |
| Open source | Yes (Excalidraw) | No |
The Whiteboard Server can be easily connected to any existing Nextcloud instance – regardless of where it is hosted. Setup takes just a few minutes:
The Whiteboard Server is provider-independent and works with Nextcloud installations at any host. Switching cloud providers is possible at any time without losing whiteboard functionality.
Which Nextcloud version is required?
The Whiteboard Server is compatible from Nextcloud 25 onwards. We recommend using the latest stable version for optimal performance and security.
How many participants can work on a board simultaneously?
The number depends on the chosen plan: Whiteboard S supports up to 10, Whiteboard M up to 30 simultaneous users. For larger teams, Whiteboard L with individual configuration is available.
Does the whiteboard also work on tablets and smartphones?
Yes. Since the whiteboard runs entirely in the browser, it can be used on any device with a modern web browser – including iPads, Android tablets and smartphones.
Can I use the Whiteboard Server with a self-hosted Nextcloud?
Yes, the server is provider-independent and works with any Nextcloud installation, whether self-hosted or with a managed hosting provider.
