Digitally sovereign

Secure video conferencing for those who value productivity, digital sovereignty, and true data protection.

User-friendly

Video conferencing can be so much more than just a black background with images and sound. They're fun and productive when everyone can find their way around intuitively and nifty features make everyday work easier. - Thanks to browser support, you can get started right away with OpenTalk without any software installation.

Productive

OpenTalk has been redesigned from the ground up and optimized for ease of use, security and stability. For pleasant, trouble-free meetings, even with many participants. Presenters benefit from well thought-out features based on many real-world use cases.

Uniquely more

OpenTalk offers unique additional functions: smart moderation options, easy communication between participants and audit-proof voting. Digital sovereignty is a matter of course for us. Decide for yourself how you want to use OpenTalk: as an online service or as your own installation.

Additional functions that are fun to use.

True added value

Group rooms (Break-out)

Group rooms can be created randomly, by number of moderators, or by group affiliation of the participants. Moderators can enter or leave those rooms at any time.

Sub-conferences (sub-room meetings)

Would you like to discuss something privately with another participant while the conference is ongoing? Open a sub-room to chat in confidence and keep following the main event at the same time.

Meetings with multiple hosts/moderators

The use of more than one moderator makes it possible to conduct conferences more efficiently in parallel, as several moderators can divide the work between them. When a conference has finished, moderators can remain in the meeting for off-boarding.

Audit-proof voting mechanism

Effective resolutions, not just talk: OpenTalk offers an auditproof mechanism for conducting open and secret votes and will reliably document the results.

High scalability

Need to serve a million participants? Not a problem. OpenTalk’s container architecture ensures stable platform operation and so, reliability and scalability for providers.

Integration

Get everything you need from a single source: Thanks to open APIs, OpenTalk can be integrated with calendars in Microsoft Outlook® or Mozilla Thunderbird.

Open interfaces and SSO

Our APIs give access to all functionality. Appearance, behaviour and features can be controlled separately. Singlesign- on (SSO) via Keycloak facilitates the seamless integration into your own systems.

Data protection and confidentiality

The GDPR, confidentiality, and secrecy protection are in our DNA. Our well-designed architecture

ensures data separation, client suitability and transparent security mechanisms.

Technical assets

Open Source

OpenTalk is open source, naturally. Developed by Heinlein, the product combines years of experience and technological finesse to a video conferencing solution that offers auditable code and free community use - in keeping with our philosophy of independence and digital sovereignty.

Performance

OpenTalk supports small-scale operation on root servers and can be easily scaled for the needs of large enterprises, national data centers or ISPs. Thanks to the Docker and Kubernetes technologies, many hundreds of conferences with very large numbers of participants can be run in parallel, securely and with high performance.

Architecture

OpenTalk is hosted on dedicated servers in Germany and implemented with a secure, high-performance programming language. Its core architecture was designed from scratch and avoids weaknesses that other conference solutions suffer from, offering 100% data sovereignty. For secure communication and data protection - fully GDPR-compliant.
