Best European Alternatives to Microsoft Teams and Zoom

Microsoft Teams is the default hub for chat, video calls, and collaboration at countless organizations, but it’s built by a U.S. company and often routes data through third-party infrastructure. If data sovereignty and privacy matter to you, a growing number of European alternatives can fill the same role while keeping your information closer to home. These platforms are GDPR-compliant, store data within the EU or Switzerland, and are built with privacy as a core principle rather than an afterthought.

Proton Meet (Switzerland)

Proton Meet comes from Proton, the Swiss company already known for Proton Mail and Proton Drive. It was built specifically to compete with Teams, Google Meet, and Zoom, and its standout feature is end-to-end encryption on every call and shared file — meaning not even Proton’s own staff can see what’s discussed. If you’re already using other Proton tools, you might also want to check out our guides on running Proton apps on Linux or getting credit through a Proton referral code.

Infomaniak kChat & kMeet (Switzerland)

Infomaniak kChat is the messaging and collaboration piece of Infomaniak’s kSuite productivity bundle. It covers team chat, direct messaging, and lightweight project organization, all hosted securely by the Swiss provider. Paired with kMeet for video calls, the two tools together form a genuine Teams substitute — fully hosted in Switzerland and built around European privacy standards.

Nextcloud Talk (Germany, Open Source)

Nextcloud Talk is the communication module inside Nextcloud, the German open-source platform for full team collaboration. It handles audio and video meetings, chat, and screen sharing, and because it can be self-hosted, you decide exactly where your data lives and how the servers are managed. That makes it a strong fit for hybrid teams that want real independence from big cloud providers.

Stackfield (Germany)

Stackfield is a German team communication service built around end-to-end encryption. It bundles chat, file sharing, audio and video calls, and project management into a single platform, making it a solid all-in-one pick for organizations that want to replace Teams without stitching together several separate tools.

Wire (Germany/Switzerland)

Wire combines messaging, voice and video conferencing, and file transfer, all protected by end-to-end encryption. It can also be deployed on-premise for organizations that need maximum control over their infrastructure, which makes it especially appealing to companies with strict internal privacy requirements.

A Few More European Options Worth Knowing

Beyond the platforms above, a couple of other open-source tools offer partial Teams-style functionality:

• Rocket.Chat — an open-source chat and collaboration platform with voice and video support, available either self-hosted or in the cloud.
• Mattermost — open-source team chat with strong integrations and audio/video capabilities added through plugins.

Why Bother Switching to a European Alternative?

The case for moving away from Teams usually comes down to a handful of recurring benefits:

• Your data stays within the EU or Switzerland, under tighter privacy laws.
• No third-party tracking for advertising or analytics purposes.
• Greater control over your own infrastructure and easier GDPR compliance.
• Many of these tools are open-source or otherwise transparent about how they work.

The Bottom Line

Microsoft Teams remains the market leader, but that comes with real privacy and data-sovereignty trade-offs. Alternatives like Proton Meet, Infomaniak’s kChat and kMeet, Nextcloud Talk, Stackfield, and Wire all offer secure, GDPR-compliant ways to chat and meet online. They’re worth a serious look for any team or organization that wants to keep its communications inside Europe while regaining more control over its data.
