Best European iMessage Alternatives (2026)

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.

Wire is a secure communication platform designed for organizations, offering end-to-end encrypted messaging, calls, and file sharing.

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.
