   Nextcloud

    1202 likes

   Nextcloud is an open source software that allows you to manage your files and sync them across all your devices - like Dropbox. There are, however, several differences: You can self-host a Nextcloud instance, allowing you to fully manage it, or you can use a Nextcloud provider to host your data for you. You have access to more security, privacy and administration options. You can add plugins for almost everything (emails, tasks, calendars, maps, news, video chats, notes, and more).

   Of course, it’s a bit more complicated to set up since you have to self-host it or find a provider, but if what you’re looking for is an open source and extensible solution that you can fully manage yourself, Nextcloud might be the right pick for you.

   Open-sourced, easy to install and maintain, close to feature parity with Dropbox (except Paper).

   With self-hosted sync, you maintain complete control over your data instead of trusting it to some third-party company. Plus, Nextcloud offers handy features like calendar integration and automatic photo uploads from your phone

   It runs well even on an old laptop or a large server, great for sharing files, collaborating on documents and managing my photo library.

   Although Seafile.de works with a slightly more complex client than does Dropbox, it also has more options. Importantly, it's open source, unlike Dropbox. Also, storing files using Seafile.de 's services mean your data is stored in Germany, which has stricter privacy laws. Note: Whilst Seafile does offer client-side encryption, at the time of writing this encrypts only file contents, not names or metadata. (Dropbox doesn't offer this at all, however.)

   They had me at .syncignore, i.e you can use a .gitignore file to just ignore files in a synced folder, useful for node_modules and stuff.

   It is a cloud storage service, which is not only an alternative to Dropbox, but also extends it, by enabling connection with Dropbox, Google Drive and OneDrive inside one application.

    Pydio is very similar to Owncloud, therefore if owncloud is deemed an alternative to Dropbox, so is Pydio

    X Cloud is the best alternative to Dropbox, iCloud, etc. because it prioritises the user's privacy. The only person who has access to your files is you. This is not true of these other providers. It also has the most beautiful and intuitive UI of all it's competitors.
