European Messaging Apps: Directory Shortlist

Wire is a secure communication platform designed for organizations, offering end-to-end encrypted messaging, calls, and file sharing. It provides flexible deployment options including cloud, on-premises, and hybrid solutions. Wire is trusted by enterprises and governments for its security, compliance, and digital sovereignty features.

Element is a secure and interoperable communications platform built on the Matrix open standard. It offers organisations control over their communications with features like end-to-end encrypted messaging, voice and video calls, and desktop collaboration. Element supports digital sovereignty by allowing self-hosted solutions and ensuring independence from vendor-locked systems.

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.

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.

Vroff is a Swedish all-in-one digital workspace that bundles video meetings, threaded chat, project management, a shared calendar, and team metrics into a single platform. Built around a rooms model — team members move between rooms to see who is available and collaborate in real time, similar to Discord but positioned for work. Developed and hosted in Sweden by the privately-owned Zápas Group (parent of SMS Teknik, TellusTalk, and InTime, a 20+ year Swedish software operator). Data is AES-encrypted at rest on Swedish cloud infrastructure; the product complies with GDPR, DORA, and NIS2. End-to-end encryption is on the roadmap but not yet shipped, and a native mobile app is planned for summer 2026. Free for up to 100 users per office.

BirdyChat is a dedicated messaging app for professionals, enabling chats that keep work conversations separate from personal ones, while also allowing users to send and receive WhatsApp messages. It is designed for focused exchanges and collaborative work, with a commitment to end-to-end encryption.
