    135 alternatives to Nextcloud 

    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.

    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.

    I have been using Nextcloud for years. I use it to share calendars, contacts and files among all my computers and devices, and with my family members. I use the Deck module (Trello alternative) to manage my work and children activities, Talk module (Zoom alternative) for video conferencing, and others. Nextcloud is simple and powerful, keep the data with myself, yet it is free. I really love it.

    223 alternatives to ownCloud 

    Like Nextcloud, ownCloud is an open source solution that you can self-host on your own server, or you can pay a monthly fee to get an online instance with limited storage. It offers interesting features such as collaborative editing and version management of documents, image galleries, end-to-end encryption, email plugins to host attachments, and more… and you can also extend it by installing add-ons from their marketplace.

    It’s no coincidence that ownCloud and Nextcloud share so many features, because Nextcloud is based on ownCloud. The key differences are the licenses (ownCloud’s enterprise edition comes under commercial license), the exclusive features ownCloud offers only to premium users while all features are free with Nextcloud, the app marketplaces (Nextcloud’s one has more apps), and of course, the pricing plans if you want a managed instance.

    Requires self-hosting, which can be a limit for many. Since a good knowledge of security related matters is mandatory, think twice before using it. However is the best alternative for those not looking for have their data hosted on a NSA server.

    113 alternatives to Syncthing 

    Syncthing is an open source software that allows you to synchronize your files and folders from multiple devices across the Internet using a secure P2P connection. It's a kind of like ownCloud/Nextcloud, but working with the Peer-to-Peer protocol without a "central" server. All communications are encrypted by the TLS protocol and each device is clearly identified with a unique identifier. This allows you to create your own cloud, and share files between your devices (Windows, Linux, macOS, BSD and Android are supported so far) without using servers hosted by third parties. And since everything is hosted on your machines, there are no hosting plans with more storage or more features, Syncthing is completely free.

    If you use Dropbox to sync files across devices Syncthing is probably more secure and you don't have to trust a central authority. Still you do not need to set up a server

    Syncthing is free, open-source, being developed actively. It allows 100%secure synchronization of files between without quota. It does not host files on an external server, which is a good or a bad thing depending on your preference.

    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.)

    Accessing your files via the website is very similar to Dropbox. Low prices, European privacy laws and open source clients compatible with Mac, Windows and Linux. Within Europe, upload speeds of the order of 1-2MB/s, download speeds 1-6MB/s depending on number of files. I got similar speeds with Dropbox in UK. Use together with Cryptomator for max privacy.

    IPFS is all VC-backed marketing hype that doesn't deliver. Also, it is not an alternative to Dropbox. IPFS is a protocol, Dropbox is a service and app. Apps use protocols, protocols don't use apps.
