Best OneDrive Alternatives for Businesses in 2026

If your business already runs on Microsoft 365, OneDrive often makes sense. It keeps files close to Word, Excel, Teams, and Windows, which makes day-to-day collaboration easy. But we have seen many teams reach a point where that convenience is no longer enough. Maybe you need more control over your data, stricter privacy protections, lower storage costs, or simply less dependence on Microsoft. Any of these reasons can make it worth reconsidering your options.

Honestly, the best alternative really depends on what you are actually trying to fix. In this guide, we compare the best OneDrive alternatives for businesses in 2026, including Nextcloud, Proton Drive, Google Drive, pCloud and Seafile, to help you find the one that actually fits how your team works.

A Quick Comparison

We selected these options based on business privacy, collaboration, self-hosting, file-sync performance and day-to-day ease of use.

1. Nextcloud

If you want my honest pick, Nextcloud is the strongest OneDrive alternative out there, especially if the whole point is to actually own your cloud instead of just swapping one tech giant for another. It's open-source, so you can run it on your own servers or have someone host it for you. Either way, you get to decide where your data lives, how storage is allocated and which collaboration tools your team uses. That kind of freedom is hard to find with the big providers.

Now, here's the catch nobody mentions up front. Self-hosting sounds great until you are the one who is responsible for server maintenance, backups and keeping on top of security updates. For many businesses, that's not realistic, and that's exactly why managed hosting exists.

With CloudBased Backup, we take care of the infrastructure and all the ongoing maintenance behind the scenes. You still manage the parts that matter to your business: your files, users, groups, sharing settings, and policies, all through Nextcloud. So you get a private cloud hosted in German data centers, without taking on the server headaches. It's basically the control of self-hosting without having to become a sysadmin.

Key Features

• Open-source private cloud that can be self-hosted or fully managed
• File sync and sharing across Windows, macOS, Linux, Android and iPhone
• Storage quotas and group folders that your business can manage centrally
• Secure sharing controls, including passwords, expiry dates and upload-only File Drop links
• Nextcloud Office for collaborative work on documents, spreadsheets and presentations
• Nextcloud Talk, Calendar, Contacts, Deck, and Flow for broader team collaboration
• Custom domain and complete visual branding for your cloud portal
• German hosting with GDPR-focused data protection practices through CloudBased Backup

Best For

Businesses that want a private, flexible alternative to OneDrive with more control over data, hosting, storage and collaboration, without managing the underlying server themselves.

2. Google Drive

Google Drive is a sensible pick as a OneDrive alternative when your company already works in Gmail, Google Docs, Sheets, Slides, and Google Meet. But let's be real. Leaving Microsoft 365 for Google Workspace isn't really about swapping one storage app for another. You are choosing a whole different way of working. Teams can create, edit, comment on, and share documents in the browser without spending time moving files between separate tools.

Here's the honest trade-off, though. Google Drive is still a Google-hosted cloud service, not a platform you can host or control yourself. For plenty of businesses, that's totally fine, because they just want a familiar, low-maintenance workspace.

Key Features

• Built into Google Workspace alongside Gmail, Docs, Sheets, Slides, and Meet
• Real-time editing, comments, suggestions, and version history for shared documents
• Shared drives for company-owned files and team folders
• Browser-based access with desktop and mobile apps
• Search tools that help teams find files, documents, and content quickly
• External sharing controls for collaborating with clients, suppliers, and partners
• No server setup, maintenance, or software updates for your IT team to manage

Best For

Businesses already using Google Workspace that want simple browser-based collaboration, strong document editing, and an easy move away from Microsoft 365.

3. Proton Drive

Proton Drive is a strong OneDrive alternative when the real concern is who can access your company’s files. It uses end-to-end encryption, which means your files, filenames, and even folder names get locked up before they ever leave your device. Put simply, Proton itself can't read what you store there. Add in the fact that Proton is based in Switzerland, and you've got a level of privacy that Microsoft and Google do not offer by default.

The trade-off is that Proton Drive is still a hosted service. You can't run it on your own servers or build your own cloud environment around it. So it's a great fit when encryption and private file sharing matter more to you than flexibility.

Key Features

• End-to-end encryption for your files, filenames, and folder names
• Secure sharing links with password protection and expiry dates
• Permission controls for invited collaborators, with access that can be changed or revoked
• Proton Docs and Proton Sheets for encrypted document and spreadsheet work
• Dedicated apps for Windows, macOS, Android, iOS, and iPadOS
• Integration with the wider Proton ecosystem, including Mail, Calendar, Pass, and VPN
• Swiss-based provider with a privacy-first approach to cloud storage

Best For

Businesses that store confidential files and want end-to-end encryption by default, especially when privacy matters more than self-hosting flexibility or an extensive collaboration platform.

4. pCloud

If all your business really needs is a simple place to store, sync, back up, and share files, pCloud is worth a look. The thing that makes it stand out is its individual lifetime plans. Instead of adding another monthly subscription, a freelancer or small business owner can just pay once and be done with it. But here's a detail that's easy to miss: pCloud Business plans are billed monthly or annually, so the lifetime option does not apply to a team business account.

For a small team, pCloud offers the essentials without much complexity. You can sync files across your devices, share folders, send password-protected links and recover earlier versions of files. Its business plans also include team management, access controls, up to 180 days of version history and pCloud Encryption for each team member. Just keep in mind that you can't self-host it, and it's primarily a storage and sharing tool.

Key Features

• Individual lifetime storage plans for those who want to avoid recurring personal storage fees
• pCloud Business plans with team management and access controls
• File sync across devices, with offline access when needed
• pCloud Drive, which lets files remain in the cloud without filling local storage
• Shared folders, password-protected links, branded shares and file requests
• File version history and Rewind for recovering earlier file versions
• pCloud Encryption, including zero-knowledge protection for business accounts
• Swiss-based provider with a choice of European Union or United States data storage locations

Best For

Small businesses that need reliable cloud storage, file sharing, and backup tools, but do not need a self-hosted platform or a full suite for documents, chat, calendars, and workflow automation.

5. Seafile

Seafile is a strong OneDrive alternative for technical teams that care most about fast, efficient file syncing and full control over where their data lives. It's open-source and you can self-host it, which means you can run it on your own server, in a private data center, or with a cloud provider you choose. Under the hood, it uses a block-based storage system, which helps avoid storing the same data twice. That makes it well suited to source code, research data, media archives, and folders containing a very large number of files.

There is a trade-off worth understanding before you commit. Seafile stores files in its own internal format rather than as ordinary files you can browse directly on the server. That improves its storage efficiency, but backups, recovery, and external integrations need to follow Seafile’s documented process. And it's really focused on file syncing, so don't expect built-in chat, calendars, or workflow tools as you'd get with a full collaboration suite.

Key Features

• Open-source Community Edition for self-hosted file sync and sharing
• High-performance syncing designed for efficient storage and file transfers
• Seafile Drive, which mounts cloud storage as a virtual drive without syncing everything locally
• Desktop clients for Windows, macOS, and Linux
• Mobile apps for Android and iOS
• Shared libraries, file version history, and secure sharing controls
• Granular folder permissions, protected links, and external upload links
• Optional integrations for collaborative Office document editing

Best For

Technical teams, developers, researchers, and media-focused businesses that need efficient self-hosted file storage and syncing, especially when high file counts or large data libraries matter more than an all-in-one collaboration platform.

Which OneDrive alternative should your business choose?

Honestly, it comes down to one question: why did you start looking beyond OneDrive in the first place? Think about what you're actually trying to fix. Is it privacy? Easier teamwork? Lower costs? Faster syncing? Or do you just want more control over where your company's data lives? Once you know that, the choice gets a lot easier.

• Choose Nextcloud if you want the most control. It is the best fit for businesses that want a private cloud, flexible storage, Linux support and collaboration tools beyond file sharing. If self-hosting feels like too much work, managed Nextcloud hosting gives you the same control without taking on server maintenance yourself.
• Choose Proton Drive if protecting confidential files is your main concern. Its end-to-end encryption is a strong fit for sensitive documents, but it is less suitable for a business that needs a highly flexible, self-hosted workspace.
• Choose Google Drive if your team already lives in Gmail, Docs, Sheets, and Meet. It offers an easy move away from Microsoft 365, especially for browser-based document collaboration, but it does not give you control over the underlying cloud environment.
• Choose pCloud if you mainly need simple storage, backup, and sharing for a small team. It is easy to use, but it is not designed to replace a complete collaboration platform.
• Choose Seafile if your company handles large data libraries, source code, research files, or folders with very high file counts. It is a strong technical option, but it requires more hands-on administration and has a narrower collaboration scope.

At the end of the day, the best choice is the one that solves the specific problem that made your business consider leaving OneDrive.
