Functions and technology
Options for an on-premise installation
OpenTalk comes with open and well-documented APIs. Clearly specified interfaces enable seamless integration into existing platforms and products. All access to features is subject to strict authentication and authorization.
REST-based APIs are available for provisioning of users and rooms, configuration, metrics, and reporting.
This enables a rich set of use cases beyond pure video conferencing and makes OpenTalk a versatile video communication solution for third-party applications.
OpenTalk utilizes modern container technology. Each conference will be launched within a container. For small-scale installations, that's usually "localhost", or alternatively, a Kubernetes cluster for anything bigger. OpenTalk takes care of the provisioning, operation and shutdown of each conference container.
Containerization ensures vertical & horizontal scaling as wells as clear data separation between conferences and participants. OpenTalk allows hassle-free operation, good management of CPUs and other resources, and avoids the "10K" scale-out issues that other solutions may suffer from. A conference container runs largely independently, which is great for administrators, as configuration changes and even system updates can be performed at all times without causing disruption.
OpenTalk supports customization of logo and colors to fit your corporte identity. Presets and features can be configured system-wide, client-by-client, or at an individual level, per conference. Giving you the flexibility to brand OpenTalk to suit your needs.
On our roadmap:
Provide background images from the server end to fit your corporate design, to be used by everyone affiliated by default.
OpenTalk supports the operation of conferences in a cluster of federated conference servers, which enables the creation of security zones. A new conference can be bound to a specific conference server, which hosts the meeting. Participants need to access this specific server to attend the meeting. This way, some conferences can be accessed only from pre-defined locations, such as the computers of your in-house network. Thus, any security-sensitive content will be protected by an additional level of security.
On the other hand, open conferences with external participants can be held in a way that optimizes traffic, using video bridge servers that are freely accessible over the Internet.
Using well-defined interfaces and APIs, all kinds of qualitative and quantitative metrics can be retrieved from the OpenTalk platform for monitoring and performance analytics.
OpenTalk allows you to stay on top of all mission-critical indicators: Server health, available resources and consumption by container, participant numbers per conference, number of connections, reconnects, other events, usage time, and many more.
Good reporting and meaningful statistics show the current status and predicts future situations, so that impending bottlenecks can be identified at an early stage and available resources allocated accordingly.

30 years of experience
The people behind OpenTalk are the competent team of the Heinlein Group, who also run the e-mail provider mailbox.org and look back at 30 years of experience in the design and operation of secure electronic communication. OpenTalk has been developed from the ground up as open source software with a modern IT architecture. Modern, stable, user-friendly, and secure.
You have the choice
On-Premise or Private Cloud: OpenTalk adapts flexibly to your needs and can be run as a stand-alone solution or also integrated as a component into an existing platform, thanks to its open interfaces. OpenTalk can be operated either within your own infrastructure (on-prem) or accessed on our servers in Germany (SaaS). OpenTalk fully implements the requirements of secrecy protection and the General Data Protection Regulation (GDPR).
Peer Heinlein, CEO OpenTalk“Good digital communication must be independent, confidential and well thought out. And that is exactly how we designed OpenTalk: as a secure alternative to established video conferencing solutions, for true data autonomy.”
Frequently asked questions
With the Community Edition, OpenTalk underlines its commitment to Open Source. It is intended for private and semi-professional use (single server system with limited number of users), but has all the essential features of a modern video conferencing solution. The installation is described -> here for technically experienced users and administrators (Linux knowledge required). We also provide the source code on the -> OpenCoDE.de platform under the -> European Public License, providing full transparency. Vendor support and support services are not provided for the Community Edition.
The Enterprise Edition is aimed at organizations that want to run a professional solution including vendor support in their own data center. In addition to advanced features, automated deployment, scaling based on containerization, monitoring and direct integration into the enterprise infrastructure are offered out of the box. Installation instructions for Enterprise Edition customers are available via protected access.
If you are interested and have any questions, please -> contact our sales department.
Licensing is based on a subscription model including support. The calculation of the annual fee is based on the number of registered users. There are no additional costs for guest participants.
If you are interested and have any questions, please contact our sales team.
OpenTalk integrates the -> Keycloak component. This allows both the management of user accounts in the system and the connection to existing user directories such as LDAP, Microsoft Active Directory or -> Univention UCS. In addition, 2-factor authentication and single sign-on can be implemented in this way.
Yes, OpenTalk currently uses Docker container technology. It provides pre-built containers for all system services that can be deployed across different systems, including high availability and horizontal scaling.
Support for Kubernetes is currently under development. Please contact our sales team if you are interested.
Yes, the Enterprise Editions can be used to create multiple tenants within the platform, as well as easily run multiple instances, allowing for complete data separation at the tenant level.
