Twitter/X Alternatieven

Element

🇬🇧

by Element

Element is a secure messenger and collaboration platform built on the Matrix open protocol, developed by Element (formerly New Vector) in London, UK. It provides end-to-end encrypted messaging, voice/video calls, and bridging to other platforms (Slack, Teams, WhatsApp). Element is used by the French government, German military (Bundeswehr), and NATO for secure communications. Organizations can self-host for complete data sovereignty, or use Element's managed hosting.

Mastodon

🇩🇪

by Mastodon

Mastodon is a decentralized social network created in 2016 by Eugen Rochko in Jena, Germany. It operates on the ActivityPub protocol, meaning anyone can run their own server (instance) that federates with the broader network — similar to how email works. There is no central company, no ads, and no algorithmic feed. Mastodon grew to over 10 million users after Twitter's acquisition by Elon Musk, and is governed by a German non-profit (Mastodon gGmbH).

Threema

🇨🇭

by Threema

Threema is a Swiss encrypted messenger founded in 2012 by Manuel Kasper in Pfäffikon, Switzerland. Unlike most messaging apps, Threema requires no phone number or email to register — users get a random Threema ID, enabling truly anonymous communication. All messages, calls, and files are end-to-end encrypted, and metadata is minimized by design. Threema is fully open source and has been independently audited. It's widely adopted in German-speaking countries and used by the Swiss government and military.

Stoat

🇬🇧

by Stoat

Stoat (formerly Revolt, rebranded in October 2025) is an open-source, privacy-focused messaging platform built in the UK. It provides a familiar Discord-like experience with servers, channels, voice chat, and rich media sharing — but with full GDPR compliance and EU data hosting. Stoat is fully self-hostable, giving communities and teams complete control over their data. It features fine-grained role-based permissions, end-to-end encryption, and does not require a phone number or real name to register. Ideal for privacy-conscious communities looking for a feature-rich alternative to Discord.

Wire

🇨🇭

by Wire

Wire is a secure collaboration platform founded in 2012 by Janus Friis (Skype co-founder) and headquartered in Zug, Switzerland. It offers end-to-end encrypted messaging, voice/video calls, and file sharing for teams. Wire is open source, independently audited, and used by government agencies and enterprises across Europe for classified communications. It supports self-hosted deployment for organizations requiring full data sovereignty.
