The NextBox Idea
To make the cloud more secure for everyone we decided to start a crowdfunding campaign with our idea. We want to reach more people and convince them not to blindly entrust their data to big-name corporations and expose themselves to more and more hidden risks. We want to offer everyone a way to give their data a safe home.

Why Crowdfunding?
Developing a new product not only costs a lot of work but also money. We produce our products exclusively in Germany and have very high quality standards. Since we are a small company without investors, we rely on the support of the community.

Automatic, Administration-Free Updates
Compared to similar systems, NextBox is characterized by maintenance-free operation. To enable this, Ubuntu Core is used, which is designed to run secure IoT systems. This is a lightweight Linux operating system that will be provided with security updates for 10 years (starting in 2018). The Nextcloud software is installed as a snap package, which is compartmentalized from the actual operating system. This enables reliable software updates, so that in the event of a failure (e.g. power failure) incompletely installed updates will be rolled back. Software is stored independently of user data, so data is preserved. All this is possible without user interaction. Therefore, no terminal/SSH access is needed to manage the system. Advanced users are of course free to install their own system on NextBox.

How is remote access from the Internet enabled?
We have put a lot of effort into providing smooth and easy-to-use remote access. NextBox can be shared using either of the following methods:

  •  The easiest-to-use method requires only the entry of a domain name, one's email address, and an authentication code included with the NextBox for configuration. Afterwards the NextBox is accessible under the chosen domain name, e.g. With this method, traffic is routed through a proxy server provided by Nitrokey. This ensures that the NextBox can be reached without any problems. It should be taken into account that, for example, when accessing via cell phone which is logged into the in-house WLAN, the data traffic is routed once to the proxy and once back to the NextBox, and thus passes the Internet connection twice.
  • If no proxy is to be used, an easy-to-use method using Dynamic DNS (DynDNS) is available. The configuration in the NextBox is also very simple, as in the above point. In addition, however, a port share (port 443) may have to be set up on the home Internet router. The use of UPnP is planned to further simplify this step. With FritzBoxes, among others, the selected domain must be released under "DNS rebinding". Since nowadays most internet connections are IPv6 capable, the use is usually problem-free. But if the client or the NextBox is not connected via an IPv6 capable access, access problems may occur.
    The DynDNS provider used is the Berlin association deSEC, which provides a modern and professional DynDNS service.
  • Advanced users can use any other DynDNS services.
  • In addition, remote access is possible using a static IP address or a self-defined domain (e.g. using the Dynamic DNS service of the Internet router).

Hello, what a great project! What about connecting a USB RAID storage? Is it possible to automatically mirror the backup from the internal drive to an external RAID System? Kind regards, Phil
Backup to USB takes just two clicks. But it's not a mirror.
Is it battery powered?
No battery.
What is the difference or why should i buy your product instead of a NAS from other companies with Web-Access?
Because it has Nextcloud with many apps, is open source and high quality from Germany.
Ist es möglich bzw. wird es möglich sein auf der NextBox weitere Dienste (ich denke da an pi-hole) zu installieren und zu nutzen?
Alle MB haben BIOS, Raspberry auch? Wenn ja,was für eins (AMI,..)
"BIOS" ist ein nicht so wohldefinierter Begriff, grundsätzlich gibt es beim Raspberry lediglich eine SoC-Firmware, welche aber unveränderbar ist. Mehr Infos findet man zum Beispiel hier:
Is it possible to install and use pi-hole on a NextBox.
Sure, the NextBox is open (you can access it via ssh) and install whatever you want as it runs on Debian. Keep in mind that only Nextcloud is supported to run on the NextBox, means if you encounter problems with pi-hole we cannot provide you support.
Kann man auf der NetBox weitere Dienste, wie z.B. pi-hole, installieren und nutzen?
Ja, man kann einen ssh-zugang einrichten und dann auf dem System alles tun, was man so auf einem Raspberry PI 4 mit Debian tun kann. Das passiert dann natürlich auf eigene Verantwortung.
super sache diese nextbox. ich überlege mir eine zuzulegen. nur habe ich eine frage: kann ich den speicher mit einem raid erweitern? die optionen mit 5tb sind zu klein und ich hätte gerne eine langfristige ausfallsicherheit. zB mit einem RAID1
Hey hey, nein leider kann man den Speicher aktuell nicht mit einem RAID1 erweitern um so redundante Datenspeicherung zu erhalten. Die NextBox ist nicht als klassische NAS angelegt, wo man etwas derartiges erwarten würde. Das liegt primär daran, dass der Raspberry PI4 einfach nicht genügend Schnittstellen für ein derartiges Setup bereit hält.
