Alternatives to Dropbox for all platforms with Open Source License

  • Nextcloud

    A safe home for all your data – Access & share your files, calendars, contacts, mail & more from any device, on your terms.

    • If you don't mind setting up your own server, NextCloud is a great Dropbox alternative because: 1) it's open source, 2) you control your data, 3) the limit of your storage is determined only by the limit of your hard drive. Alternatively, you can get services to host a NextCloud install on their servers for you, but then you give that service access to your data. Unless you encrypt client side with something like Cryptomator first. JohnFastmanDec 2016 • 17 agrees and 1 disagrees Disagree   Agree
    • Open-sourced, easy to install and maintain, close to feature parity with Dropbox (except Paper). PaourFeb 2017 • 14 agrees and 2 disagrees Disagree   Agree
    • Nextcloud is totally private with a great variety of additional apps, to customize the server fully to your personal needs. And it's all free (if you host it yourself). And there is even no limitations for storage space. They even offer free apps/ clients for Android, iOS and Windows (Phone). Contacts, (shared) Calendars, internal Chat, live collaboration on office documents and soon to come end-to-end encryption - what else would you need?!
