Nextcloud gives you access to all your files wherever you are.
Where are your photos and documents? With Nextcloud you pick a server of your choice, at home, in a data center or at a provider. And that is where your files will be. Nextcloud runs on that server, protecting your data and giving you access from your desktop or mobile devices. Through Nextcloud you also access, sync and share your existing data on that FTP drive at school, a Dropbox or a NAS you have at home.
Nextcloud is free, open source and you can get involved in making it better!Get started
Because your data is everywhere
Right now, nearly ALL data there is about you is stored at half a dozen companies, with names changing per country (Facebook, wechat, Vk, Google, Weibo, Tencent, Microsoft). They know where you live, what you search for, who you talk to, what you buy, what you eat and --probably-- what you think.
Because knowledge is power
Your data represents who you are and can easily be abused.
And power gets abused. Always. Maybe by a local politician who doesn't like that you discovered his fraud. A local police woman who likes your boyfriend. A well connected businessman who likes to buy your store for cheap. A crime syndicate annoyed you try to help drug addicts kick off.
Maybe you just care about privacy
Even if your data isn't abused --they promise not to, right?-- isn't it nobody's business what you do?
We believe privacy is a right, a foundation for democracy. And we like to help you get it back.
And running your own, private Nextcloud server is the best way to get started!
Nextcloud is people
Nextcloud is an open source community of developers and contributors, some helping out in their free time, others paid by their company to make Nextcloud better.
We organize events, attend conferences, hang out together at meetups and hackweeks. If you would like to meet Nextclouders, check out our events page!
Share with others on your terms.
The easy web interface allows you to share files with other users on your server, to create and send password protected public links, to let others upload files to your cloud and to get notifications on your phone and desktop when a user on another cloud server shares files directly with you. And you can do all these things from the desktop or mobile clients, too.Share with Nextcloud
We are deeply committed to protecting the safety of your data and we're certain that Nextcloud offers the best security in the self hosted file sync and share world, because:
we follow industry best practices around security (aligned to ISO27001)
we offer some of the highest open source security bug bounties
we integrate unique in-transit, server-side and client-side end-to-end encryption technologies.Security in Nextcloud

Build your own website!

Automatically upload files to replace large attachments or integrate Calendars and Contacts in your mail client
The Nextcloud Secure Sharing Outlook Add-in enables Nextcloud users to easily and securely send files, folders or upload links to others from within Microsoft Outlook.

It also makes it easy for users to provide others with a secure file upload link.

Thanks to the Mozilla Thunderbird Lightning Calendar add-in and the Cardbook Thunderbird Contacts add-in, Calendar and Contacts integrate great into Thunderbird.
