Infomaniak kDrive

Google Workspace is convenient because Gmail, Drive, Docs, Calendar, Meet, and admin tools all work together. The trade-off is that many European users and businesses now want more control over where work data is hosted, how documents are processed, and whether collaboration tools fit their GDPR and digital sovereignty requirements.

This guide compares the strongest European alternatives to Google Workspace for people, startups, and organizations that need email, documents, cloud storage, calendars, contacts, and team collaboration without defaulting to a US hyperscale suite. If your search is narrower, our related guides cover Gmail alternatives, Google Drive alternatives, Google Docs alternatives, Google Sheets alternatives, and privacy apps.

What counts as a European Google Workspace alternative

A good European cloud office suite should do more than put servers in Europe. We looked for tools that meet at least one of these practical tests:

No single option here is a perfect one-click clone of Google Workspace. Infomaniak kSuite and Proton Workspace are the closest managed bundles. Nextcloud Hub is the strongest self-hosted platform. ONLYOFFICE and Collabora Online are best treated as document engines inside a broader stack.

The best European alternatives to Google Workspace in 2026

1. Infomaniak kSuite: best managed European Google Workspace alternative

Infomaniak kSuite is the closest managed replacement for a business that wants a European cloud office suite without running servers. Infomaniak is based in Switzerland, and its kSuite page lists Mail, kDrive, kChat, kMeet, Calendar, Contacts, Docs, Grids, and Points in one account.

For users searching for Google Workspace alternatives in Europe, the practical advantage is packaging. kSuite combines a European Gmail alternative, a Google Drive alternative Europe buyers can use under Swiss hosting, and Office-compatible document editing. Infomaniak says kSuite is developed and hosted in Switzerland, compliant with GDPR and Swiss FADP, and backed by its own Swiss data centers.

kSuite also has a clear personal entry point. The free personal kSuite includes an email address, 20 GB for email, and 15 GB of cloud storage. kSuite Pro is the business tier, with central billing, team collaboration, unlimited email storage, and up to 6 TB of cloud storage per user according to Infomaniak’s published plan page.

Strengths: The suite is coherent, privacy-focused, and easier to adopt than self-hosting. kDrive has mobile and desktop apps, and kSuite Pro adds the business pieces that individuals do not need.

Limitations: It is not self-hosted. If your policy requires running the service on your own infrastructure, Nextcloud Hub is a better fit. kSuite also depends on OnlyOffice for online document editing rather than being a Google Docs clone built from scratch.

Best for: Small businesses, agencies, nonprofits, and teams that want managed European cloud hosting with mail, drive, meetings, chat, and document editing.

Use it: kSuite, kDrive, Aptoide listing

Bottom line: Pick Infomaniak kSuite first if you want the simplest managed European alternative to Google Workspace.

2. Nextcloud Hub: best self-hosted sovereign cloud collaboration platform

Nextcloud Hub is the strongest choice when the requirement is control. Nextcloud GmbH is based in Germany, and Nextcloud Hub combines Files, Talk, Groupware, Office, Assistant, and automation in one modular workspace.

The key difference from Google Workspace is deployment. Nextcloud says Hub can run on-premises, with a trusted hosting provider, or in a hybrid setup. That makes it one of the clearest sovereign cloud collaboration tools for organizations that need to decide where data lives, who administers it, and which providers can access it.

Nextcloud covers file sync, sharing, desktop and mobile clients, chat, video, calendars, contacts, and mail integration. For document editing, it normally relies on Collabora Online through Nextcloud Office or integrations such as ONLYOFFICE. That modularity is useful, but it also means the quality of the final setup depends on the admin team and hosting provider.

Strengths: Self-hosting, open-source code, broad app ecosystem, strong integration with groupware, files, and office editing.

Limitations: Nextcloud is not a casual signup replacement unless you choose a managed provider. Performance, backups, upgrades, identity integration, and storage policy all become your responsibility.

Best for: Organizations needing self-hosting, schools, public-sector buyers, regulated companies, and technical teams with infrastructure ownership.

Use it: Nextcloud Hub, Nextcloud Enterprise, Nextcloud privacy

Bottom line: Pick Nextcloud Hub when digital sovereignty means owning the deployment, not just choosing a European vendor.

3. Proton Workspace: best privacy-first bundle for mail, drive, docs, and calendar

Proton Workspace is now a serious privacy-first Google Workspace alternative for teams that value encrypted communication over Office feature depth. Proton is based in Switzerland, and its business page positions Proton Workspace as a privacy-first alternative to Google Workspace and Microsoft 365.

The bundle includes Proton Mail, Calendar, Drive, Docs, Sheets, Meet, VPN, Pass, and business administration features depending on plan. Proton says the suite protects business data with end-to-end encryption, Swiss jurisdiction, and compliance support such as ISO 27001, SOC 2 Type II, HIPAA, CCPA, and GDPR claims.

For an individual, Proton is a strong European Gmail alternative and a privacy-friendly Google Drive alternative. For a company, the more relevant question is whether Proton Docs and Sheets cover enough document workflow. They are improving, but they are still younger than Google Docs, Sheets, or mature self-hosted office engines.

Strengths: Strong privacy model, encrypted mail and storage, custom-domain email, import tools, and a growing document layer.

Limitations: No self-hosting. Heavy spreadsheet users and teams with complex document templates should test Proton Docs and Sheets before migration.

Best for: Individuals, startups, legal/finance teams, journalists, nonprofits, and privacy-focused teams that need encrypted email plus secure file collaboration.

Use it: Proton for Business, Proton pricing, Proton Drive

Bottom line: Pick Proton if privacy is the reason you are leaving Google Workspace.

4. Tuta Mail: best encrypted European Gmail alternative

Tuta Mail is not a full Google Workspace replacement, but it is one of the strongest European Gmail alternative picks for users who mainly need encrypted email, calendars, contacts, custom domains, and team administration. Tuta is based in Germany and says all user data is stored on its own servers in ISO 27001-certified data centers in Germany.

The Tuta business page lists custom domains, shared mailboxes, branding, multiple administrators, calendar sharing, email import, GDPR data processing agreements, and business plans starting at EUR 6 per user per month when paid yearly. Tuta also says emails, calendars, contacts, subject lines, and address book data are encrypted.

The fit is narrow but clear. If your organization asks for a GDPR-friendly productivity suite because Gmail is the problem, Tuta solves the email and calendar part well. If your team needs Docs, Sheets, Drive-style storage, video meetings, and workflow automation, pair Tuta with another tool or choose kSuite, Proton, Nextcloud, or Mailbox.org instead.

Strengths: Strong email privacy, encrypted calendar and contacts, open-source clients, custom domains, and German hosting.

Limitations: No full Google Docs-style office suite. Self-hosting the service is not available.

Best for: Privacy-focused individuals, freelancers, small teams, nonprofits, and companies that primarily need secure email and calendar.

Use it: Tuta Business, Tuta pricing, Tuta open source

Bottom line: Pick Tuta when replacing Gmail matters more than replacing every Google Workspace app.

5. Mailbox.org: best standards-based European email and office suite

Mailbox.org is a German email and digital workspace provider aimed at private users, SMEs, public-sector buyers, and organizations that prefer standards-based tools. The business page lists Mail, Drive, Meet, Office, and Admin in one service.

Mailbox.org is especially practical for businesses that want managed email hosting without Big Tech lock-in. It says data remains in Europe, services are hosted on its own servers in Germany, and the company has ISO 27001 certification and BSI C5 testing. Business plans start at EUR 1 per user per month for Light, with Standard at EUR 3 and Premium at EUR 9 per user per month before VAT.

The Standard and Premium plans add Drive, calendar and address book, Office, and Meet. Mailbox.org also offers migration help through Audriga for email, calendars, contacts, and cloud files, which matters for teams leaving Gmail or Microsoft 365.

Strengths: Low starting price, German hosting, mature email, calendar, contacts, drive, office, and migration services.

Limitations: The office experience is more conventional groupware than a slick Google Docs replacement. It is managed hosting, not a self-hosted platform.

Best for: SMEs, public-sector adjacent organizations, privacy-conscious families, and teams that want managed German email plus office basics.

Use it: Mailbox.org Business, Mailbox.org private plans, Mailbox.org security

Bottom line: Pick Mailbox.org if you want a practical GDPR-friendly productivity suite built around strong email and open standards.

6. Open-Xchange OX App Suite: best for service providers and public-sector platforms

Open-Xchange OX App Suite is different from the consumer tools in this guide. It is mainly sold to hosting providers, telcos, ISPs, and public-sector deployments that want to offer their own email, calendar, documents, storage, tasks, and collaboration platform.

Open-Xchange is a German company with offices in Cologne, Bremen, Hamburg, and Olpe. Its OX App Suite page describes a white-label email, productivity, and collaboration platform with email, calendar, documents, drive, tasks, provider tooling, integrations, and cloud or on-premise deployment. The company also highlights OX Guard for OpenPGP-based encryption and large-scale provider operations.

For a typical startup, OX is probably too provider-oriented. For a European hosting company, government supplier, university IT body, or managed-service provider, it is much more relevant because it lets the provider own the brand, domains, customer relationship, and deployment model.

Strengths: Provider-grade email and collaboration, white-labeling, on-premise or cloud deployment, public-sector relevance, and integrations with storage and document tools such as Nextcloud and Collabora Online.

Limitations: Sales-led and operator-focused. Most small businesses should buy a hosted service built on OX rather than trying to procure it directly.

Best for: Hosting providers, telcos, ISPs, public-sector platforms, and organizations building a sovereign workspace for many users.

Use it: OX App Suite, Open-Xchange company page, Open-Xchange locations

Bottom line: Pick Open-Xchange when you need to provide a European workspace service, not just subscribe to one.

7. ONLYOFFICE: best privacy-friendly Google Docs alternative for Office files

ONLYOFFICE is one of the strongest document-editing options if your Google Workspace usage centers on Docs, Sheets, Slides, PDF forms, comments, review, and Microsoft Office file compatibility. ONLYOFFICE says it is owned by Ascensio System SIA, a Latvian company that is a subsidiary of OnlyOffice Capital Group Pte. Ltd., according to its official FAQ.

ONLYOFFICE Docs Enterprise covers document, spreadsheet, presentation, PDF, form, co-editing, comments, version history, chat, and audio/video call integrations. It can run as a cloud service or on your own server, and it has connectors for platforms including Nextcloud, ownCloud, Moodle, WordPress, and others.

This is not the best standalone answer if you need a European Gmail alternative or calendar. It is best as the office layer inside a sovereign stack: Nextcloud plus ONLYOFFICE, ownCloud plus ONLYOFFICE, or ONLYOFFICE DocSpace for room-based collaboration.

Strengths: Excellent Office-format focus, self-hosting, free desktop and mobile apps, open-source community builds, strong document collaboration.

Limitations: ONLYOFFICE Docs alone does not replace Gmail, Calendar, or Drive. Workspace and DocSpace products cover more, but buyers should choose the deployment carefully.

Best for: Teams that need document fidelity, self-hosted document editing, Nextcloud integration, or a privacy-friendly Google Docs alternative.

Use it: ONLYOFFICE, ONLYOFFICE Docs Enterprise, ONLYOFFICE security

Bottom line: Pick ONLYOFFICE when document editing is the hard part of leaving Google Workspace.

8. Collabora Online: best LibreOffice-compatible document engine for sovereign stacks

Collabora Online is another strong document layer for European-friendly and self-hosted collaboration. Collabora Productivity is based in Cambridge, United Kingdom, and has a broad European open-source footprint, including a German managing director and deep LibreOffice involvement.

The Collabora Online page describes collaborative editing for documents, spreadsheets, and presentations that can integrate into existing infrastructure. It supports Microsoft Office and OpenDocument formats, works with Nextcloud and other platforms, and emphasizes data sovereignty because documents remain in the chosen infrastructure.

Collabora’s free CODE edition is useful for testing, home use, or small teams, but Collabora explicitly says it is not recommended for production. Businesses should use supported Collabora Online subscriptions or a managed provider.

Strengths: Open source, strong ODF and Office compatibility, Nextcloud integration, production support, public-sector fit.

Limitations: It is not a full suite by itself. You still need storage, identity, email, calendar, and admin around it.

Best for: Organizations building a sovereign office stack with Nextcloud, ownCloud, Open-Xchange, or another European platform.

Use it: Collabora Online, Collabora CODE, Collabora subscriptions

Bottom line: Pick Collabora Online when your stack needs a mature open-source document editor under your control.

9. CryptPad: best encrypted collaborative docs for sensitive small-team work

CryptPad is a French-made, end-to-end encrypted collaborative office suite developed at XWiki in Paris. It is not a Gmail or Calendar replacement, but it is one of the most privacy-friendly Google Docs alternatives for sensitive notes, documents, spreadsheets, forms, whiteboards, kanban boards, and shared workspaces.

CryptPad encrypts data in the browser, so readable document content does not leave the user’s device. Its about page says even service administrators cannot see document or user-data contents. The software is fully open source and can be self-hosted.

The pricing model is transparent. Public instances and self-hosting are free options. CryptPad.fr paid plans add storage and priority support for individuals, teams, and organizations, while managed enterprise instances start from published yearly pricing.

Strengths: End-to-end encrypted collaboration, open source, self-hosting, anonymous or low-friction sharing, strong docs for privacy-focused groups.

Limitations: No email, no direct Gmail replacement, and not a broad enterprise admin suite like Google Workspace.

Best for: Journalists, NGOs, schools, activist groups, privacy-focused teams, and small teams that need private collaborative documents.

Use it: CryptPad, CryptPad pricing, CryptPad about

Bottom line: Pick CryptPad when document confidentiality matters more than suite completeness.

How to choose by user profile

Individual user

Pick Proton if private email, encrypted cloud storage, and simple document sharing are the priority. Pick Infomaniak my kSuite if you want free European mail and kDrive storage in one account. Pick Tuta Mail if you mostly need a private inbox and calendar.

Small business

Pick Infomaniak kSuite if you want the lowest-friction managed European Workspace replacement. Pick Mailbox.org if standards-based email, calendars, drive, office, and migration support matter more than a highly polished docs interface. Pick Proton Workspace if encryption is more important than advanced office editing.

Startup

Pick Proton Workspace if your startup handles sensitive customer data, legal documents, or investor communications. Pick kSuite Pro if you want a managed European cloud office suite with chat, meetings, drive, and document editing. Pick Nextcloud Hub only if your team has someone ready to own infrastructure.

Privacy-focused team

Pick Tuta Mail for encrypted email and calendar. Add CryptPad for encrypted collaborative documents if you do not need a full office suite. Pick Proton Workspace when you want one vendor for mail, calendar, drive, docs, and secure sharing.

Organization needing self-hosting

Pick Nextcloud Hub as the base. Add Collabora Online or ONLYOFFICE for document editing, and consider Open-Xchange if you are building a provider-scale email and collaboration platform.

Company needing managed European cloud hosting

Pick Infomaniak kSuite first. Compare Mailbox.org if email and open standards are central. Compare Proton Workspace if encryption and Swiss privacy are central. Avoid self-hosted stacks unless you have internal IT capacity or a trusted managed-service provider.

Migration checklist before leaving Google Workspace

Before switching, map the jobs Google currently handles for you:

Then test with real work. Move a shared folder, a complex spreadsheet, a recurring calendar, and one external-collaboration workflow. A GDPR-friendly productivity suite is only useful if the daily workflow survives the move.

FAQ

What is the best European alternative to Google Workspace?

Infomaniak kSuite is the best first choice for most teams that want a managed European alternative to Google Workspace. It combines email, kDrive storage, document editing, calendar, contacts, chat, meetings, and team administration in a Swiss-hosted service. Nextcloud Hub is better if self-hosting is required.

Is there a GDPR-friendly productivity suite in Europe?

Yes. Infomaniak kSuite, Mailbox.org, Proton Workspace, Nextcloud Hub, and several self-hosted combinations can be configured as GDPR-friendly productivity suites. The important part is the contract and deployment: check the data processing agreement, hosting location, subprocessors, retention settings, access controls, and migration path.

What is the best European Gmail alternative?

Proton Mail, Tuta Mail, Mailbox.org, and Infomaniak Mail are the strongest European Gmail alternatives in this guide. Proton and Tuta are best for encryption-first users. Mailbox.org and Infomaniak are better if you want email inside a broader managed productivity suite.

What is the best Google Drive alternative in Europe?

Infomaniak kDrive is the simplest managed European Google Drive alternative for most users. Proton Drive is stronger for encrypted storage. Nextcloud Files is the best option when you need self-hosted or provider-hosted storage under your own policy.

Can a business self-host a Google Workspace alternative?

Yes. The most practical route is Nextcloud Hub plus Collabora Online or ONLYOFFICE for document editing. Larger providers or public-sector platforms can also look at Open-Xchange for email and productivity services, but that is a provider-grade product rather than a simple small-business subscription.

Are European cloud office suites as complete as Google Workspace?

Some are close, but the trade-offs differ. Infomaniak kSuite and Proton Workspace cover many core jobs in one subscription, while Nextcloud can cover even more if properly deployed. Google Workspace still has a smoother default experience for real-time docs, search, and third-party integrations, so teams should pilot real workflows before migration.
