Can Nextcloud Actually Replace Google Workspace? We Tested It.
A hands-on evaluation of Nextcloud Hub 26 Winter as a self-hosted alternative to Google Workspace for small and medium businesses.
Every business runs on email, documents, calendars, and video calls. For most, that means Google Workspace or Microsoft 365 — reliable, polished, and deeply embedded in daily workflows. But there’s a growing number of organizations asking a simple question: do we really need to hand all of our data to Google or Microsoft?
The reasons vary. Some are driven by GDPR compliance. Others by cost. Some just don’t like the idea of a single vendor controlling their entire digital workplace. Whatever the reason, the question leads to the same place: what’s the alternative?
We spent a day evaluating Nextcloud Hub 26 Winter — the latest release of the most popular self-hosted collaboration platform — to find out whether it’s a viable replacement for Google Workspace in a real business setting.
Here’s what we found.
What Nextcloud Actually Covers
The first surprise is scope. A single Nextcloud installation gives you:
- Files — cloud storage with sharing, versioning, and group folders (Google Drive)
- Collabora Online — browser-based editing of Word, Excel, and PowerPoint files with real-time co-editing (Google Docs/Sheets/Slides)
- Talk — chat, video calls, screen sharing, and call recording (Google Meet + Google Chat)
- Calendar & Contacts — scheduling, meeting proposals, and address books that sync with your phone and desktop apps (Google Calendar + Contacts)
- Deck — Kanban boards for task management (Trello)
- Tasks — to-do lists that sync with your phone’s reminders app (Google Tasks)
- Forms — surveys and data collection with public links (Google Forms)
- Whiteboard — collaborative drawing and diagramming (Miro/FigJam)
- Notes — simple note-taking (Google Keep)
That’s five to six Google products replaced by one self-hosted platform, under one login, with one consistent interface.
The Cost Argument
Let’s talk numbers. Google Workspace ranges from $7 per user per month (Starter) to $18+ (Standard) — and that’s before add-ons. For a 100-person company on the Standard plan, that’s roughly $21,600 per year.
A Nextcloud deployment on a mid-range cloud server costs roughly $100-200 per month in hosting — call it $1,200-2,400 per year. The software itself is free and open source. Collabora Online, which powers the document editing, offers a free Development Edition with the same core editing capabilities. Paid plans add long-term support and guaranteed security updates.
That’s roughly a 10x cost reduction before you factor in the value of owning your data.
Of course, self-hosting isn’t free of effort. Someone needs to manage the server, handle updates, and troubleshoot issues. But for organizations that already have IT staff — or work with a managed service provider — the economics are compelling.
How Does It Actually Feel?
The verdict: it works. Navigation is responsive, core features are accessible, and the interface — while busier than Google’s minimalist design — is coherent and functional. It works well on both desktop and mobile browsers.
Nextcloud also offers native apps for iOS and Android, plus desktop sync clients for Windows, Mac, and Linux that support on-demand file access, similar to Google Drive’s desktop experience.
The document editing experience through Collabora is solid for typical business documents. It handles .docx, .xlsx, and .pptx files natively, supports real-time co-editing with multiple cursors, and includes comments and track changes. It’s not pixel-perfect with heavily formatted Office documents — but neither is Google Docs. For everyday business use, it gets the job done.
Accessibility
We ran automated accessibility tests across every major Nextcloud app. Scores ranged from 87 to 100 out of 100. The issues found were minor — nothing that would prevent someone using assistive technology from getting their work done.
Where It Falls Short
No honest evaluation skips the gaps. Here’s where Nextcloud doesn’t match Google Workspace:
This is the biggest one. Nextcloud does not include email hosting. It has a webmail interface that can connect to an existing email provider, but it doesn’t send or receive email on its own. If you’re replacing Google Workspace end-to-end, you need a separate email solution.
This isn’t unique to Nextcloud — running your own email is one of the hardest parts of going independent from Google. But it does mean a Nextcloud deployment is not a complete Google Workspace replacement out of the box. You’ll need to either run a separate email server or use a privacy-respecting email provider like Proton Mail or Migadu alongside Nextcloud.
Threading in Chat
Nextcloud Talk — the chat and video calling component — is functional and improving, but its threading support is still buggy in Hub 26 Winter. The UI shows a Threads tab, but replies don’t consistently appear in it. For teams that rely heavily on threaded conversations (Slack-style workflows), Talk may not be sufficient today.
Scaling
Nextcloud’s All-in-One installer is excellent for deployments up to about 100 users. Beyond that, you need a more complex multi-server setup — splitting the database, file storage, and application across separate machines. There’s no simple out-of-the-box path to grow beyond that. Nextcloud does offer enterprise-grade scaling tools, but only to paying customers.
Migration
Official migration tools exist for Google (calendars, contacts, files), OneDrive, and Dropbox — but they’re not actively developed anymore. The OneDrive tool doesn’t work with Business accounts. There’s no built-in way to bring over chat history from Slack or Teams. Calendars and contacts transfer cleanly, and files can be moved with third-party tools, but it’s not a one-click process.
Backup
The built-in backup system briefly takes the platform offline while it runs. For businesses that need 24/7 availability, this can be supplemented with server-level snapshots or external backup tools that don’t require downtime.
Security and Compliance
This is where Nextcloud genuinely shines for businesses with regulatory requirements.
Data sovereignty is total. You choose the server, the storage backend, and the jurisdiction. No data leaves your infrastructure unless you configure it to.
Audit logging is enabled by default, tracking who logged in, who accessed what files, who shared what with whom, and all administrative changes. These logs can be exported to specialized security monitoring tools — a requirement for many compliance frameworks.
Encryption is available at multiple levels: data is encrypted automatically while travelling over the internet, files can be encrypted on the server’s storage, and for the most sensitive documents, end-to-end encryption ensures that only the intended recipients can read them — not even the server administrator.
The security track record is clean. As of February 2026, across 248 published security reports, only one was ever rated critical — and it was promptly fixed and only affected a niche configuration. Nextcloud runs a public bug bounty program that pays researchers to find vulnerabilities before bad actors do, and publicly discloses everything. That transparency is a sign of a mature, trustworthy project.
For GDPR compliance, self-hosting means your data stays where you put it — no third-party cloud provider involved. For SOC 2 and ISO 27001, the platform provides the technical building blocks; your organization provides the policies. HIPAA is the main exception: if you handle medical data, you may need a Business Associate Agreement with your software vendors, which could require paid support tiers.
The Community Behind It
Nextcloud is not a side project. It has over 34,000 stars on GitHub (a measure of developer interest), receives roughly 120 code updates per week, and has more than 1,300 contributors from around the world. Multiple versions are maintained simultaneously, with updates every two to four weeks. Every part of the project — server, mobile apps, desktop client — is actively worked on daily.
The project is backed by Nextcloud GmbH, a German, employee-owned company with approximately 100 employees. Enterprise support subscriptions are available but not required to use the software. The company has been around since 2016 and shows no signs of slowing down.
This matters because choosing a collaboration platform is a long-term commitment. Nextcloud’s community health and commercial backing make it one of the lowest-risk open source projects you can build on.
The Bottom Line
Nextcloud is not a perfect replacement for Google Workspace. Email is a separate problem. Scaling requires effort. Migration tooling is underdeveloped. Some features — like chat threading — are still catching up.
But it is a viable one. For small and medium businesses that care about data ownership, regulatory compliance, or simply reducing their dependence on Big Tech, Nextcloud offers a remarkably complete platform at a fraction of the cost. One installation, one interface, one login — covering files, documents, calendars, video calls, task management, and more.
The question isn’t really whether Nextcloud can replace Google Workspace. It can, with caveats. The real question is whether the trade-offs — self-hosting responsibility, some rough edges, a separate email solution — are worth the control you gain in return.
For a growing number of organizations, the answer is yes.
