OwnCloud is an open‑source private‑cloud solution that allows you to store, sync and share files on your own servers. The main goal is to provide a self‑hosted alternative to public‑cloud services such as Dropbox or Google Drive, while keeping control over your data. In this review I will analyse OwnCloud’s features, explain how to install it, examine its strengths and limitations, and compare it to other similar solutions. This approach enables companies to adopt an open‑source cloud that meets sovereignty and security challenges, while benefiting from an open‑source service supported by an active open‑source community.
What problems does OwnCloud solve?
Many organisations or professional users want to avoid depending on public‑cloud services for reasons of confidentiality, cost or compliance. Commercial cloud solutions can be expensive or restrict access to important data, whereas OwnCloud offers a self‑hosted and free alternative. This choice allows the deployment of a customisable cloud solution, while benefiting from a broad technical support ecosystem thanks to the open‑source community.
OwnCloud also provides cross‑platform synchronization between computers and mobile devices, which is essential for distributed teams or advanced users.
Key features and capabilities
Below is an overview of OwnCloud’s flagship features:
Interface
The web interface is clear and ergonomic, with sync clients available for Windows, macOS and Linux. Mobile apps exist for iOS and Android, making the use of a private cloud easy in a professional context.Performance
OwnCloud is built to handle large volumes of files. It can use caching mechanisms such as Redis to boost performance, making it a flexible cloud solution that can scale according to your needs.Customisation
OwnCloud offers many extensions via apps. Administrators can tailor server behaviour or add complementary functionalities to create a true open‑source service oriented to business needs.Security
OwnCloud includes server‑side encryption, audit logs, advanced access controls and two‑factor authentication in certain editions. These features strengthen the capabilities of an open‑source cloud that meets strict security requirements.
Installation: how to install and configure
Steps to install OwnCloud:
Prerequisites
Vous devez disposer d’un serveur Linux, de PHP et de ses extensions, d’une base de données compatible et d’un serveur web Apache.Download and installation

Use the web wizard or the OCC command‑line tool to configure the instance, create the admin account and set database parameters.Post-installation
Configure background jobs, enable a high‑performance cache and secure access with HTTPS. These practices guarantee optimal operation and facilitate long‑term technical support.
Use cases
A SMB can install OwnCloud on an internal server to store and share sensitive documents securely.
Development teams may use OwnCloud to centralise technical files or synchronise project environments.
Power users often install it on a NAS or personal server to retain full control of their data through a reliable open‑source solution.
