What Is Nextcloud? The Private Cloud Your Business Actually Controls

You've probably got files stored in the cloud already. Maybe it's OneDrive because it came with your Microsoft 365 subscription. Maybe it's Google Drive because you've been using Gmail for years. Perhaps it's Dropbox, or iCloud, or some combination of all of them.

Here's something that doesn't always get said out loud: with most of those services, your files are sitting on someone else's servers, processed by someone else's systems, and subject to someone else's terms and conditions. That's not necessarily a dealbreaker, but it's worth knowing. And it's exactly the problem that Nextcloud was built to solve.

At Tranquil IT, Nextcloud is the cloud platform we use ourselves and recommend to our clients. Here's why.

So, What Exactly Is Nextcloud?

Nextcloud is an open-source cloud platform that gives you everything you'd expect from a cloud storage service: file sync, sharing, access from any device, and collaborative editing, but hosted on your own infrastructure (or ours, on your behalf) rather than a Big Tech data centre.

Think of it like having the convenience of Google Drive or Dropbox, but where the storage lives on a server that belongs to you or your business. You're not locked into a vendor, not paying for storage you don't control, and not agreeing to terms that let a corporation scan your documents to improve their ad targeting.

Nextcloud is free and open-source, which means its code is publicly audited and there's no hidden business model running underneath it. The way it makes money is simple: enterprise support contracts and optional paid add-ons for large organisations. For everyone else, the core platform is entirely free to use.

The Problem with Big Cloud

To understand why Nextcloud matters, it helps to understand what you're agreeing to when you use mainstream cloud services.

When you store files in Google Drive, those files live on Google's servers. Google's systems scan them: for malware, yes, but also for content that informs the rest of Google's services. Microsoft does similar things with OneDrive. These companies are based in the United States, which means your data can be subject to US law, including legislation that allows government agencies to request access to data held by US companies, even if that data belongs to a business or individual in the UK or Europe.

For many people, this is a perfectly acceptable tradeoff. For others, particularly businesses handling sensitive client data, legal documents, financial records, or personal information, it isn't.

What Nextcloud Can Do

Nextcloud isn't just a file storage box. It's a full collaboration platform. Here's what comes built in:

• File sync and sharing. Upload files, sync them across your devices, and share folders or individual files with colleagues or clients using a simple link. Works from any browser, or via dedicated desktop and mobile apps.
• Collaborative document editing. Nextcloud integrates with Collabora Online and OnlyOffice, so you can open, edit, and co-author Word documents, spreadsheets, and presentations directly in your browser, with no Microsoft 365 subscription required.
• Calendar and contacts. A built-in calendar and contacts app that syncs with your phone and desktop clients, without routing your diary through Google or Apple.
• Talk: secure chat and video calls. Nextcloud Talk gives you a private, encrypted alternative to Teams or Zoom for internal calls and messaging. Everything stays on your server.
• Automatic photo backup. The Nextcloud mobile app can automatically back up your phone photos to your server the moment you take them, exactly like Google Photos, but without Google.
• Version history. Every file keeps a full version history. Accidentally overwrite something? Roll it back in a few clicks.

You can also extend Nextcloud further with a large library of community apps, covering everything from project management and e-signatures to email hosting and two-factor authentication.

Why We Use and Recommend It

We evaluated a lot of cloud platforms before settling on Nextcloud. What kept us coming back was the combination of four things that are genuinely hard to find together.

Real data ownership. When we deploy Nextcloud for a client, their files live on a server we manage on their behalf, in a location we both know and agree on. There's no ambiguity about where the data is, who can access it, or what happens to it.

No per-user storage limits. Most cloud services charge you per user and per gigabyte. With Nextcloud, your storage is as large as the hardware underneath it. Scaling up means adding a bigger drive, not upgrading a plan.

Privacy by design. Nextcloud doesn't scan your files for advertising or train AI models on your data. What's on your server stays on your server.

It just works. The desktop sync client, the mobile apps, the browser interface: they're all polished and reliable. We've used it daily for years and it holds up.

How Does Nextcloud Compare to the Alternatives?

Is Nextcloud Right for You?

Nextcloud is a great fit for most of our clients, but it isn't for everyone. Here's a quick way to think about it.

You'll love Nextcloud if you want your data to stay in the UK, if you're running a business and have obligations around where client data is stored, if you'd rather pay a fixed hosting cost than an ever-increasing per-user subscription, or if you simply want a cloud service that doesn't treat your files as a product.

The main consideration is that Nextcloud does need to be hosted somewhere. You can run it on your own hardware, a rented server, or (the simplest option for most of our clients) let us handle the setup and hosting entirely. We manage the server, apply updates, handle backups, and make sure everything stays running. You just get a login and a fast, private cloud that works.

If you're already using File History for local PC backups or Time Machine on your Mac, adding Nextcloud as your offsite cloud copy is the final piece that completes a solid 3-2-1 backup strategy. One that you control end to end.

Getting Started with Nextcloud

If you want to explore Nextcloud on your own terms, Nextcloud offers a free trial you can spin up in minutes. Their features page gives a thorough overview of everything the platform can do.

If you'd rather have it set up properly from the start (hosted, configured, and ready to use): that's exactly what we do at Tranquil IT. We handle the technical side so you can focus on using it.
