# Which Nextcloud alternatives are worth considering? A comparison

There are many powerful, open-source Nextcloud alternatives. However, they differ significantly in terms of features, data protection, and use cases. We explain which solutions are suitable for which requirements and how ownCloud, Seafile, Syncthing, SparkleShare, and FileCloud compare.

## What is Nextcloud?

[Nextcloud](https://www.ionos.com/en-ie/digitalguide/server/tools/what-is-nextcloud/) is a free cloud solution that includes Cloud storage as well as teamwork and groupware tools. The software is suitable for both private and business use.

The proven strengths of this open-source application include:

- a large selection of Nextcloud apps, collaboration tools, and extensions
- role and permission management
- GDPR-compliant use with suitable hosting
- an active community and regular development
- a choice between self-hosting and managed hosting

Compared to many alternatives, Nextcloud offers more than file storage. It provides a **complete work platform with additional features** such as Office integration and communication tools.

## What to look for in Nextcloud alternatives

Not every Nextcloud alternative offers the same range of features. Many solutions focus more closely on specific areas, such as synchronisation, security, or file sharing. As a result, the best choice depends on what you need most. Important criteria when comparing alternatives to Nextcloud include:

- **Feature set**: file synchronisation only or a complete platform?
- **Hosting model**: self-hosting, managed hosting, or peer-to-peer
- **Data privacy and security**: encryption, server location, and access control
- **Collaboration**: co-editing, versioning, and comments
- **Performance**: resource requirements and speed when handling large files
- **Administrative effort**: easy setup or more complex configuration

## All Nextcloud alternatives at a glance

There are many open-source solutions for license-free Cloud software. We present **five interesting Nextcloud alternatives** with different strengths and use cases.

Since most of these are open-source solutions, **self-hosting or managed hosting with a suitable provider** gives you more control over data storage, security measures, and cloud security.

## ownCloud

The open-source solution [ownCloud](https://owncloud.com/ "ownCloud website") enables file synchronisation and collaborative work across devices and locations. As private Cloud software, it combines **real-time teamwork, file sharing, and centralised data storage**. This makes ownCloud similar in purpose to Microsoft 365 or [iCloud](https://www.ionos.com/en-ie/digitalguide/server/tools/what-is-icloud/), while still giving users the option to self-host the platform. It is suitable for private users as well as companies with around 25 employees or more. In addition to the free version, ownCloud offers paid packages with customer support and additional features.

**Key features:**

- centralised storage, editing, and sharing of files and content, regardless of location, time, or device
- comprehensive management for creating groups, file shares, and access rights
- upload chunking to split large files into smaller packages
- options for self-hosting on your own servers or using managed hosting
- activity stream with an event log for actions and file access
- collaboration on Office documents with and support for Microsoft Office and LibreOffice
- file versioning and optional file locking
- extensive administrative access features
- very good web interface
- reliable data security for compliance and data protection
- good compatibility with Linux-based systems

Note Since late 2023, ownCloud has been part of Kiteworks, a US-based technology company. While ownCloud’s open-source status remains unchanged and the platform continues to be actively developed, organisations with strict European data sovereignty requirements should factor this ownership change into their evaluation.

## Seafile

[Seafile](https://www.seafile.com/en/home/ "Seafile website") is open-source software with features similar to cloud storage services like Dropbox, including file sharing and file transfer. Unlike Dropbox, however, Seafile uses open, license-free source code on both the server and client side. With comments, clear file versioning, messaging, and client-side end-to-end encryption, Seafile is especially useful for **collaborative work on files and content**. The software is available as a free version and as a Professional Edition.

**Key features:**

- centralised storage, editing, and sharing of files and content, regardless of location, time, or device
- file sharing and file transfer through central data storage on the cloud server
- file sharing with selected users via link
- particularly fast file synchronisation and file versioning
- useful collaboration tools for teams and projects, such as comments and messages
- easy installation

## Syncthing

With [Syncthing](https://syncthing.net/ "Syncthing website"), you get an open-source solution for **peer-to-peer file synchronisation**. Instead of relying on your own or hosted Cloud storage, Syncthing synchronises files directly between computers over the internet. Files remain on users’ local devices while still being updated and shared via device ID.

By eliminating the need for a central Cloud server, Syncthing also reduces one potential attack surface for cyberthreats. Its web interface provides useful tools for **custom access management, folder configuration, and statistics**. Additional devices can also be connected for synchronisation and file sharing via ID.

**Key features:**

- real-time data synchronisation between computers over the internet via device ID
- assignment of rights and access permissions for shared files and folders
- practical web interface for configuring settings, shares, and additional devices

    </tr>
    <tr>
      <td>additional devices can be connected via ID</td>
      <td>requires more technical understanding than traditional Cloud services</td>
    </tr>
  </tbody>

## SparkleShare

The open-source solution [SparkleShare](https://www.sparkleshare.org/ "SparkleShare website") is available for Linux, macOS, and Windows, though Linux support is most mature. It is therefore mainly used for **administrative file management on Linux systems**. With a file hosting service, SparkleShare can synchronise files and make them available centrally on a local or hosted server. Git version control makes it possible to restore files and track changes. This is especially useful in larger projects with many access rights, where teams need a clear overview of file status at all times. Since SparkleShare is based on Git, it can also be seen as a graphical frontend for Git.

In September 2024, the developer announced in a [GitHub post](https://github.com/hbons/SparkleShare/issues/2006 "github.com: future of the SparkleShare project") that the project would **no longer be actively developed** due to time constraints, though he has since indicated a possible rewrite in Rust. Although the application remains usable for now, the future of SparkleShare is uncertain.

**Key features:**

- central provisioning and cross-device, encrypted file synchronisation
- easy file restoration and traceable changes thanks to Git version control
- simple desktop integration with a dedicated directory for folders and files

## FileCloud

[FileCloud](https://www.filecloud.com/ "FileCloud website") is file-sharing software designed primarily for businesses. Its main strengths are **security, administration, and compatibility**. The platform is highly flexible and integrates with many widely used programs and Cloud services, including Microsoft Office, AWS, and Google Workspace. The graphical user interface can be customised, for example with a company logo, and data formats can be adapted to the end user’s location. You can host a FileCloud server yourself or use FileCloud’s hosted option.

Administrators can manage access rights for individual devices and remotely delete data from those devices when needed. FileCloud also supports automated deletion of private user data. With FileCloud-hosted deployment, companies can choose the country where their data is stored, making it easier to meet internal data protection and compliance requirements.

**Key features:**

- cross-device compatibility and synchronisation
- security features such as AES-256 encryption, SSL/TLS protocols, and login via SSO and/or two-factor authentication
- flexible customisation of the user interface based on company preferences or localisation, plus the option to self-host the server
- numerous integrations with popular software packages and Cloud services
- simple and comprehensive device and file management, with some automation options
- unlimited versioning
