Team-Spaces
In OpenCloud, Spaces represent a new approach to team-based file collaboration: all content is assigned to the Space β not to individual user accounts. This ensures that files remain permanently available within the team context, even if employees leave the company. Projects become more robust, efficient and scalable in the long term.
Hyperscale architecture
OpenCloud is a tried-and-tested, state-of-the-art cloud-native microservices platform. Instead of a monolithic stack, it relies on asynchronous processing and an API-first approach. For users, this means a noticeably fast, responsive interface with real-time updates β even with large numbers of users, large folders and high workloads.
File management

Collaboration & productivity
Spaces
Spaces are shared workspaces for teams and projects. They bundle files, folders and authorisations so that content is retained even when personnel change.

Shared Drive
Files belong to the Space and not to individual user accounts. This means that content is retained even if team members leave the project or organisation.
Internal sharing
Securely share files and folders in OpenCloud with colleagues, teams or groups. Rights control reading, editing and uploading in File Sync & Share.

External sharing
Share files in OpenCloud securely with customers, partners or authorities - via a password-protected link.

Notifications
OpenCloud informs you in the browser, desktop client, app or by email about new shares, changes and Space members in the activity feed.
Federation
Federation connects multiple OpenCloud installations and other compatible systems via the Open Cloud Mesh (OCM) protocol. Files are automatically made available across locations.
Contacts & Calendar
Use calendars and contact lists in OpenCloud from Apple Calendar, Outlook, Thunderbird, or Radicale services.
Usability & user experience
Intuitive clients
In the browser and desktop client, you use OpenCloud like a file manager: drag & drop, multiple selection and keyboard shortcuts speed up your work.

Fast user interface
The OpenCloud interface remains fast even with many files. Asynchronous updates shorten loading times.
Realtime UI
As soon as data changes, this appears immediately in the web interface - without manually reloading the page.
View modes & responsive design
Display files in list or tile view, customise columns and use the responsive web interface from smartphone to 8K.

Branding and look & feel
Customise the OpenCloud web interface to your corporate design: Logos, colours and themes - including a dark mode option.
Accessibility
The OpenCloud web interface fulfils WCAG 2.1 AA / BITV 2.0 and EAA: keyboard navigation, clear labelling, contrasts and screen reader support increase accessibility.
Compliance & data protection
Digital rights management (DRM)
Secure View in OpenCloud adds watermarks to documents and makes it more difficult to take unauthorised screenshots or share sensitive content.
Compliance
OpenCloud supports organisations in implementing key data protection and security requirements, for example in the areas of GDPR, ISO 27001, CCPA, HIPAA, FERPA or SOC 2.
Encryption
OpenCloud encrypts all data during transmission.
Virus protection
Automatic virus protection in OpenCloud scans files for malware and ransomware. File firewall and rollback protect your cloud storage from attacks.
Audit logs
Audit logs in OpenCloud log file uploads, approvals and logins. Actions are traceable per user and support audits and compliance.
Eco-label
OpenCloud has been awarded the Blue Angel DE-UZ 215 ecolabel for resource- and energy-efficient software.
Identity and access management (IAM)
Strong passwords
Password policies in OpenCloud enforce strong passwords. Banned Password List and Generator increase IT security in the company.
Biometric unlocking
Unlock the OpenCloud app on mobile devices using fingerprint or facial recognition. Biometric login increases security and convenience.
Role-based control
Role-Based Access Control (RBAC) in OpenCloud manages authorisations via roles and enforces passwords or expiry dates for share links, for example.

Multi-Account
Use multiple accounts in parallel in OpenCloud desktop and mobile to separate clients, projects or private and business environments.
Single Sign-On (SSO)
With single sign-on via LDAP, Active Directory or IdPs, employees access OpenCloud with centralised company access data.
Session monitoring
Administrators monitor active sessions in OpenCloud and terminate or time-limit them to prevent unused or risky access.

Operation and provision
Cloud-native architecture
OpenCloud was developed from the ground up as a cloud-native solution. The architecture uses microservices and is optimised for container technologies such as Docker and Kubernetes. This enables flexible deployment and rapid adaptation to modern IT requirements.
File Native Backup
With OpenCloud, a simple backup of the file system using a snapshot or file copy is sufficient for a completely consistent backup. This significantly reduces the effort, complexity and risk of failure, and files can be easily backed up and restored (backup & restore).
Scalable infrastructure
The solution supports both horizontal and vertical scaling. This means that additional servers or resources can be easily added to keep pace with increasing demands without compromising performance.
Independent of databases
OpenCloud has made a conscious decision not to use relational databases and instead uses files to store metadata. This decision simplifies the system considerably and at the same time helps to improve scalability and system stability.
High parallelism
Thanks to development in the GO programming language, OpenCloud can run a large number of simultaneous processes in parallel. This ensures fast and smooth utilisation, even with large amounts of data.
Containerisation
With support for containerised applications, OpenCloud offers maximum flexibility. The software can be easily deployed in different IT environments, from on-premise to multi-cloud environments.
Lower operating costs
Automated scaling and optimised load distribution ensure that the system remains cost-effective even when requirements increase.
