Say Hello to OpenTalk!

The secure video conferencing solution from Germany.
Created with usability, digital sovereignty and scalability in mind.
Digitally sovereign

We believe that video conferencing should offer great features, high productivity and a personalized user experience. Where security is not optional but a fundamental requirement.

Welcome to OpenTalk.


Digital Sovereignity

„Good communication starts with open communication. That's how we designed OpenTalk - secure video conferencing that empowers digital sovereignty.“

User Experience

Video conferencing has become a productivity tool just like other groupware.

A clear and vibrant visual design and a rich set of features make our solution stand out from the crowd. Ease of use is very important to us and browser support avoids any software installation hassles. Personalization options are key to make the UI meet your needs.


OpenTalk was developed from scratch and optimised for usability, security and stability. A modern architecture ensures best scalability and support for many use case scenarios.

OpenTalk is based in Germany and fully GDPR-compliant.


OpenTalk offers many unique communication and moderation features, and even a audit-compliant voting system.

OpenTalk provides all this out of the box, and can support scenarios with many users. Digital sovereignty and technology that works.

Available at mailbox.org

Currently, you can already use OpenTalk as an integrated offering with the email provider mailbox.org. In mid-2023, OpenTalk will launch its own SaaS offering with increased limits and enhanced functionality.
