OpenSlides Hosting in Germany
WZ-IT provides OpenSlides hosting, installation and technical operations for digital meetings, including hardening, backups, monitoring and preparation for critical event dates.
About the technology
OpenSlides for meeting, committee and election management
OpenSlides is an open-source platform for agendas, motions, speaker lists, votes and elections. User imports, roles, devices, networks and support must be tested before the event.
We assess participant numbers, functions, locations and criticality and design a rehearsal, deployment, monitoring and recovery plan.
OpenSlides features for meetings and elections
Manage agendas
Prepare and publish the schedule, items, documents and responsibilities centrally.Process motions
Organise motions, amendments, status and deliberation sequences transparently.Control speaker lists
Manage requests to speak and sequence during the assembly in a structured way.Participants and roles

Test TLS, network paths, authentication and administrative interfaces before use.Evaluate results
Export resolutions, voting results and minutes information within the intended scope.Provide documents
Share templates, attachments and assembly materials centrally with the intended participant groups.Prepare procedures

Import participants, committees and prepared content through supported formats in a controlled way.Model multiple committees
Structure organisations, committees and separate meetings with suitable roles and access boundaries.Support the event technically
Prepare monitoring, capacity, recovery and escalation paths for critical event dates.
Operations beyond installation
Operate OpenSlides as an event-critical platform
Assembly software must do more than remain available. Participant import, roles, documents, projection and voting procedures must be tested together before the event.
Assembly platform
Install, configure and update OpenSlides and its services in a controlled process.Motions and participants
Back up and handle the database, files, imports and exports completely and transparently.Identity and access
Secure users, roles, SSO and external access paths for the event.Test and event
Prepare load tests, monitoring, recovery and escalation before critical dates.
Area
Responsibility between platform operations and organiser
WZ-IT is responsible for the agreed technical operations. The organiser defines procedures, permissions and the authoritative results.
| Area | Responsibility | Scope and boundaries |
|---|---|---|
| Platform and infrastructure | WZ-IT | Deployment, proxy, database, services, monitoring and agreed technical maintenance. |
| Backup and recovery | WZ-IT | Backups of database, files, configuration and keys plus agreed restore verification. |
| Participant import and roles | Shared | We support import and technical roles; the organiser supplies and validates participant and permission data. |
| Rehearsal and load profile | Shared | WZ-IT provides the technology and measurements; the customer tests the actual event procedure. |
| Electoral and procedural rules | Customer | Legal admissibility, statutes, electoral rules and business approvals remain with the organiser. |
| SSO, streaming and custom integration | Optional WZ-IT service | Identity providers, live streaming, custom exports and other integrations are planned separately. |
Hosting & operations
How much does OpenSlides hosting cost?
We combine the right compute size with ongoing operations, backups, monitoring and a service level appropriate for the criticality of OpenSlides. High availability and recovery targets are designed separately where needed.

As an alternative to managed hosting in the data centre, WZ-IT provides the hardware, configures OpenSlides, and handles hardening, monitoring, updates, backup and technical support. Access can be limited to the internal network or enabled through VPN and existing identities.
View WZ-IT App Node →Sizing and deployment
Size OpenSlides by participant count and event risk
The number of registered accounts is not enough. Concurrent users, votes, projection, uploads and time-critical peaks determine the architecture.
| Usage scenario | Technical starting point | Key factors |
|---|---|---|
| Small committee or internal meeting | Technical starting point S or M | Normal usage with limited concurrency and a planned schedule. |
| Association or assembly with many participants | Load and procedure review | Concurrent logins, votes and projector views are tested. |
| Multiple parallel meetings | Individual platform architecture | Tenant boundaries, capacity, data retention and operations are designed separately. |
| Business-critical election or major event | Recovery and readiness concept | Redundancy, recovery, support paths and rehearsal are agreed explicitly. |
- The configuration captures a technical starting point. A binding proposal follows review of features, participants, event risk and integrations.
Sizing and deployment

The location follows participant access, privacy, existing infrastructure and required technical responsibility.

Target architecture
From participant access to secured results
We design the complete chain of access, identity, OpenSlides services, data retention and recovery.
Participants and organisation
Members, delegates, guests, administration and event technology.
Secured access
TLS, reverse proxy, network rules, rate limits and VPN where required.
Accounts and roles
Imported users or SSO with minimal administrative permissions.
OpenSlides platform
Agenda, motions, speaker lists, votes, projectors and exports.
Database and services
Stateful platform services and consistent data retention.
Files and backups
Documents, configuration, keys and encrypted backups.
Monitoring and events
Technical metrics, error signals and agreed escalation paths.
Technical operations alone do not establish the legal admissibility of a vote or election. The organiser remains responsible for the procedure and business approval.

Reviews & projects
Client feedback and projects worldwide
WZ-IT moved our studio infrastructure from decentralised individual devices to a central platform: every site is securely connected via VPN, new devices are onboarded automatically and an entire site is provisioned from a template, without manual steps on location. What impressed me most is the breadth and depth of their knowledge: Timo and Robin are not a typical IT provider who sets up a server and leaves. The two of them think their way into highly complex infrastructure and software topics, work through every requirement we put in front of them, and build networking, provisioning and operations so that everything fits together in the end. WZ-IT is an excellent partner for complex software, network and architecture projects.
