5. Syncany

Released in about an year ago in near March 2014, Syncany is one of the lightest and open source cloud storage and file sharing application. It is currently being actively developed by Philipp C. Heckel and as of today, is available as a command line tool for all supported platforms, but GUI version is under active development.

One of the most important feature about Syncany is that it is a tool and requires you to bring in your own storage, which can be FTP or SFTP storage, WebDAV or Samba Shares, Amazon S3 buckets etc.

Other features which make it an awesome tool to have are: 128-bit AES+Twofish/GCM encryption for all the data leaving the local machine, file sharing support with which you can share your files with your friends, offsite storage as chosen by user instead of provider-based storage, interval-based or on-demand backups, binary compatible file versioning, local deduplication of files. It can be more advantageous for companies who want to use their own storage space rather trusting some providers provided storage.

Not just a file sharing or synchronization tool or software, Cozy is bundled as a complete package of functions that can help you build your complete App Engine.

Like Syncany, Cozy provides flexibility to user in terms of storage space. You can either use your own personal storage or trust Cozy team’s servers. It relies on some open source software’s for its complete functioning which are: CouchDB for Database storage and Whoosh for indexing. It is available for all platforms including smartphones.

Main features which make it a must to have Cloud storage software are: ability to store all the Contacts, Files, Calendar, etc in the Cloud and sync them between laptop and smartphone, provides ability to user to create his own apps and share them with other users by just sharing Git URL of the repository, hosting static websites or HTML5 video game consoles.

As a step further to provide its availability even for cheap hardware’s, Cozy team has introduced Cozy Light which performs well even on cheap hardware’s like: Rasberry Pi, small Digital Ocean VPS etc.

    I am missing 2 very popular open source cloud storage solutions: yunohost.org and sandstorm.io. Also ArkOS.io is an slow growing but lightweight environment for home use.

  5. Gheorghe says:

    Hello, good article, but if you mentioned for each cloud storage how many GB are per free account, that would be great.

    • Ravi Saive says:


      Thanks for finding this article useful, yes we do agree that we would’ve mentioned about storage per account, but their storage changes regularly, so its difficult for us to check every-time and update the article, you can get the details about storage on their official page..

      your point is noted, but they keep change their storage very ofenly, so

  6. David says:

    This is a great compilation although I believe you missed out syncthing.net

  7. John says:

    Numbers 10 (Yandex Disk) and 11 (Bitcasa) aren’t open source. It’s the same as saying Amazon S3 is free.

    You missed one: http://barebonescms.com/documentation/cloud_storage_server/

    Replace 10 or 11 with the above software?

    • Gunjit Khera says:

      Accept your point.
      Thanks for updating about cloud storage server
      Would try to replace above 10 and 11 with this

  8. Yannis says:

    I don’t see how No.10 (Yandex.Disk), fits in this list. Am I missing something?
