Very easy setup -


Syncthing is an open-source solution for practical peer-to-peer file syncing. It doesn’t rely on cloud storage for syncing data and uses the internet instead. This means that files stay on users’ local devices but can still be updated and shared in realtime using device IDs.

In eliminating the cloud server, Syncthing provides one less opportunity for potential attacks. In addition, its practical web interface offers tools like user-defined assignment of access and privileges, folder integration and statistics. Additional devices can be added using the ID.

The most important features:

  • Practical collaboration and realtime data syncing between computers using device IDs and the internet (peer-to-peer)
  • Assignment of privileges and access to unlocked files and folders for selected users
  • Helpful web interface for configuring roles, unlocking files or connecting additional devices

Peer-to-peer syncing in realtime between devices without a cloud server Connecting and syncing multiple devices is somewhat complicated
Practical web interface for admin and configuration settings, privileges and access No file system monitoring
Connecting additional devices with an ID is no problem Problems can arise with Linux-based systems


This open-source solution SparkleShare is focused on Linux, making it one of the preferred softwares for administrative management on Linux systems. SparkleShare can be used to sync files and store them centrally on a local or hosted server. Git version control ensures that files can be restored and changes can be tracked. That ensures that status of files is always clear, even when it comes to large projects with a lot of users with access. Since it’s based on Git, SparkleShare can also be seen as a graphic front end for Git.

The most important features:

  • Centralized file sharing and encrypted syncing across devices
  • Simple file restores and tracked changes with Git version control
  • Easy desktop integration with a special directory for files and folders
Pros Cons
Fast, data syncing and collaboration across devices Suboptimal client encryption (files names not encrypted on server)

You can either self-host your FileCloud server or have FileCloud host it.

Admins can manage the access privileges of each individual device and also delete data from those devices remotely. You can also automate the deletion of private user data using FileCloud.
