OpenCloud review 2026: features, ownCloud fork history, pricing plans from EUR2 per user, and how this sovereign file-sharing platform compares to Nextcloud.
OpenCloud is an open-source file management, sharing, and collaboration platform built on a fork of ownCloud Infinite Scale (OCIS). The fork was created in 2024-2025 by developers and community members following ownCloud's acquisition by Kiteworks, driven by governance and transparency concerns similar to those that led to the earlier Nextcloud fork in 2016.
The project is developed by OpenCloud GmbH, part of the Berlin-based Heinlein Group, a German company focused on digital sovereignty and data protection whose other products include the mailbox.org email service and the OpenTalk video conferencing platform.
OpenCloud provides core file collaboration functionality: file storage and versioning, full-text search, granular sharing controls, end-to-end encryption, and multi-factor authentication, accessible via web, desktop, and mobile clients.
Commercial tiers add enterprise capabilities such as high availability and Kubernetes support, custom branding, air-gapped deployment for high-security environments, multi-tenancy, EUDI Wallet integration, and SLA-backed support with guaranteed response times.
The Community Edition is free and open source, self-hosted at no license cost with community support through public channels. It is well suited to organizations comfortable managing their own infrastructure and support.
Commercial plans are billed per user per month: Basic (EUR2/user/month) for up to 100 users with community support, Professional (EUR4/user/month) with SLA-backed email support and high availability for larger deployments, and Premium (EUR8/user/month) with 24/7 phone support, multi-tenancy, and custom branding. A High Performance Computing add-on is priced at EUR10 per terabyte per year for large-scale storage integrations.
