Messaging platform
Mattermost server, configuration and edition are deployed and updated in a controlled process.
WZ-IT plans, installs and operates Mattermost as managed hosting, in your cloud or on premises. Depending on the target design, we also provide migration, secure network and identity integration, monitoring, backups, updates, integrations and further development.
The following are trademarks of their respective owners: Mattermost (Mattermost, Inc.). WZ-IT is an independent service provider and has no business, partnership, or contractual relationship with these companies. We offer independent migration, installation, hosting, and operations services.
Mattermost is a self-hostable messaging and collaboration platform for organisations that want deliberate control over infrastructure, data location and integrations. Available SSO, compliance and scaling features depend on the selected edition.
As an independent service provider, we support you in installing, configuring, and integrating this powerful communication platform into your existing IT landscape.
We install, host and operate Mattermost for your company - either on our secure, privacy-focused infrastructure in Germany or other locations, as well as on-premise in your own environment.
We provide 24/7 monitoring, backups and maintenance for your Mattermost instance. Human response times and support coverage follow the selected service level.
Production team communication requires application, database, file storage, push services, identities and integrations to be operated together.
Mattermost server, configuration and edition are deployed and updated in a controlled process.
Database, uploads, retention and search are designed around team size and usage.
Identity providers, webhooks, bots and DevOps systems are connected securely.
Monitoring, backups, updates and agreed response paths keep the platform operational.
We operate the technology; policies for content, roles and retention remain with the customer.

Full-service installation with no hidden costs
Mattermost follows a consistent API-first approach. Every action you perform in the UI runs through the same API we use. This makes integrations predictable and stable.
Mattermost offers one of the most comprehensive APIs in the open-source space. We use the official Go and JavaScript drivers for seamless integrations - automatic channel creation from your CRM, user management via LDAP sync, or bidirectional data synchronization with your ERP.
For quick integrations, we use incoming/outgoing webhooks. Messages from monitoring tools (Prometheus, Grafana) land directly in channels. Actions like server restarts or deployments can be triggered via slash commands (/deploy production) directly from chat.
When webhooks aren't enough, we develop native plugins. These run directly on the server (Go backend) and in the client (React frontend). This allows us to modify the UI, add buttons to the message bar, or implement deep logic with database access.
How we implement Mattermost development in practice.
DevOps teams need to switch between terminal and chat for routine tasks. Checking server status, triggering deployments, or retrieving logs requires context switching.
We develop slash commands and bots that work directly in chat. /deploy production rolls out, /status shows server metrics, /logs api-server streams the latest entries. All without leaving chat.
Sales reps maintain data twice - in CRM and team chat. Updates on deals, contacts, or tasks get lost.
Middleware synchronizes your CRM (HubSpot, Salesforce, Twenty) with Mattermost. On contract close, a bot automatically posts to the sales channel. Contact cards can be retrieved via /contact [name].
Alerts from monitoring systems (Prometheus, Grafana, Wazuh) end up in emails or separate dashboards. Response time suffers.
An incident bot receives alerts via webhook, automatically creates a dedicated channel, invites relevant team members, and posts context (logs, metrics). Playbooks are started automatically.
Active users, messages, uploads, search, integrations and calls shape the platform more than the number of registered accounts.
| Usage scenario | Technical starting point | Key factors |
|---|---|---|
| Small team using channels and files | S or M | Storage growth and active users are monitored and scaled when required. |
| Multiple teams and many integrations | M or L plus storage | Bots, webhooks, search and file uploads are included in sizing. |
| Calls, high message load or long history | Custom architecture | Supporting services, search, database and storage are assessed separately. |
| Business-critical or highly available platform | Custom architecture | Clustering, database, storage, push and recovery require an aligned target design. |
The calculator models a standard workload without a separate vendor licence. Calls, Enterprise features and HA are scoped individually.
Mattermost can run on WZ-IT infrastructure, in your cloud, on-premises or integrated with internal systems. Edition and vendor licence are scoped separately.
Operations on European infrastructure with compute, storage, backup and a selectable service level.
Operations in your cloud with existing network, security and identity services.
Integration with your virtualisation, data centre and internal operations processes.
Mattermost is connected to Git, monitoring, ticketing, SSO and secure remote access.
The communications platform becomes part of your operations. Access, integrations, data paths and emergency processes are therefore designed together.
Browsers, desktop and mobile clients plus internal and external users.
TLS, reverse proxy, network rules and optional private access through NetBird or VPN.
Local accounts or connected identity providers with agreed roles and groups.
Channels, messages, playbooks and integrations on a controlled runtime.
PostgreSQL, retention, indices and, at scale, a separate search architecture.
Upload storage, mobile notifications and consistent offsite backups.
Git, CI/CD, monitoring, ticketing, webhooks and custom ChatOps integrations.
Available SSO, compliance, clustering and retention features depend on the selected Mattermost edition and vendor licence.
Answers about editions, migration, integration and operations.
No. The displayed price describes WZ-IT infrastructure and operations. If required features need a paid Mattermost edition, the vendor licence is quoted separately.
Yes, after assessing available exports, users, files, integrations and the target edition. We plan a test migration, cutover and fallback.
We support technical integration with existing identity providers. The available method and provisioning features depend on the selected Mattermost edition and are checked in advance.
Not by default. Calls create a separate load and network profile. We size and price the required components from concurrent participants and the target topology.
Yes. Application, database, storage, proxy, search and, where relevant, Calls and push need to be designed together. Vendor features and licences are included in the assessment.
Yes. We integrate webhooks and existing tools or develop bots, plugins and middleware for DevOps, incident and business processes.
Depending on the setup, we back up database, file storage and configuration consistently. Retention and recovery objectives are agreed; isolated backup files alone are not a complete restore plan.
Yes. We support roles, teams, channels, permissions and the technical rollout. Training and change-management services are agreed according to the project scope.
Yes. Critical changes can use a separate staging environment with a defined approval and rollback process. Whether this needs additional workloads depends on the architecture and data volume.
We review release notes, edition and extensions, protect the relevant data and perform updates in agreed maintenance windows. Major upgrades can be tested in staging first.
Typical signals include availability, resources, database, file storage, queues, search components and backup jobs. Monitoring and retention are limited so message content is not collected unnecessarily.
We integrate official clients, push services and available MFA or SSO methods. Which functions work without external services or extra licences is checked for the selected edition.
Mattermost is a self-hostable communications platform with channels, direct messages, files and integrations. Community and paid editions differ for some identity, compliance and clustering functions; we verify the required edition before planning.
It can run on WZ-IT infrastructure, in your cloud account, on premises or in a hybrid setup with internal services. Network, data location, access paths and operating responsibilities are defined in the target design.
For new production environments we design the database supported by the selected Mattermost version together with file or object storage, search and backups. Existing MySQL installations are assessed separately before takeover.
The agreed scope can include provisioning, baseline hardening, monitoring, backups, updates, incident handling and planned scaling. The service description and selected service level are binding, not the label by itself.
Active users, message load, uploads, search, integrations, Calls, retention and availability targets determine compute, database, storage and whether a distributed architecture is needed.
We design separated roles, MFA or SSO, private administration paths, logging and break-glass procedures. The implementation depends on edition, identity provider and the existing network architecture.
Audit, export and retention functions partly depend on the selected edition. We configure technically available controls; the customer defines legal retention and deletion rules and the permissibility of content.
Yes. We integrate available Playbooks, incoming and outgoing webhooks, slash commands and Git, CI/CD, monitoring or ticket systems. Availability and licence requirements are checked for each integration.
Whether you run Mattermost in-house or need to host confidentiality-professional data §203-ready - we build, operate and maintain Mattermost on an encrypted on-site server. Data never leaves the building in cleartext.
