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.

Answers to the most important questions
Topics
Mattermost is an open-source messaging and collaboration platform for teams. It offers channels, direct messages, file uploads, integrations and enterprise features like compliance exports and playbooks.
Yes. We handle setup, operations and maintenance (updates, monitoring, backups, incident handling) - so you can use Mattermost productively without building your own ops resources.
Both are possible: on our infrastructure (e.g., Germany, other locations) or on your infrastructure (on-prem / your own cloud account) - depending on requirements for control, network connectivity and processes.
Mattermost supports PostgreSQL and MySQL as databases. For production, we recommend PostgreSQL with appropriately configured setup (connection pooling, backups, replication if needed).
Yes. We set up automated backups and plan (depending on package) regular restore checks, so recoveries don't remain "theoretical" in case of emergency.
Typically in 4 steps: (1) Requirements & user count, (2) Target setup (domains, SSO, policies), (3) Deployment + baseline hardening, (4) Handover + operations (monitoring/backups/updates).
Yes. We can set up separate environments (e.g., staging for updates/tests and prod for live) - with separate instances, domains and access concepts.
Typically included: Provisioning + hardening, updates & patch management, monitoring/alerting, backups/restore, incident response and ongoing operational tasks (e.g., scaling as agreed). Details are package-dependent.
Yes. We agree on maintenance windows (e.g., outside your peak times), test changes (optionally first in staging) and announce plannable updates in advance.
Yes - depending on needs, we set up HA architectures (e.g., multiple app servers behind a load balancer + replicated database). Mattermost Enterprise supports clustering for high availability.
This depends heavily on user count, message volume, uploads and features. Mattermost provides sizing guides for this; we size an appropriate setup from it (and scale later).
Typically technical metadata like metrics, logs, alerts (e.g., utilization, error rates) are generated. We can set up monitoring to match your requirements (e.g., "only in region X", defined retention). What exactly is captured is documented transparently.
Mattermost Team Edition (free) supports local accounts, OAuth 2.0 (GitLab, Google, Office 365) and MFA/2FA. AD/LDAP and SAML 2.0 are Mattermost Enterprise features and require a paid license key per deployment.
Yes - we help with technical configuration (IdP parameters, attributes, group sync, role mapping) and continue to operate the environment stably. Since SAML/LDAP are part of Mattermost Enterprise, you also need a Mattermost Enterprise license key. We are happy to procure it on your behalf.
Yes, Mattermost supports MFA (Multi-Factor Authentication) via TOTP apps like Google Authenticator or Authy.
Standard baseline: least privilege, separate admin roles (System Admin, Team Admin), 2FA/SSO, IP/VPN access (optional), logging/monitoring and defined processes for changes and incidents.
Yes. Mattermost Enterprise offers compliance exports, message retention policies, custom terms of service and audit logs. These features require a Mattermost Enterprise license key (purchased separately) and are particularly relevant for regulated industries.
Playbooks are structured workflows for recurring processes like incident response, onboarding or release management. They include checklists, automations and can be linked to channels.
Yes. Mattermost supports incoming/outgoing webhooks, slash commands and has an app marketplace with integrations (Jira, GitHub, GitLab, Jenkins, etc.). We help with technical connection.
Yes. Mattermost offers native apps for iOS and Android. For self-hosted instances, push notifications can be configured via the Mattermost Push Proxy or your own HPNS (Hosted Push Notification Service).

“WZ-IT's advice on our Azure migration was technically sound and completely non-binding right from the intro call - we took away a great deal.”

“With Timo and Robin, you're not only on the safe side technically - you also get the best human support! Whether it's quick help in everyday life or complex IT solutions: the guys from WZ-IT think along with you, act quickly and speak a language you understand. The collaboration is uncomplicated, reliable and always on an equal footing. That makes IT fun - and above all: it works! Big thank you to the team! (translated)”

“I recently worked with Timo and the WZ-IT team, and honestly, it turned out to be one of the best tech decisions I have made for my business. Right from the start, Timo took the time to walk me through every step in a simple and calm way. No matter how many questions I had, he never rushed me. The results speak for themselves. With WZ-IT, we reduced our monthly expenses from $1,300 down to $250. This was a huge win for us.”

“WZ-IT manages our Proxmox cluster reliably and professionally. The team handles continuous monitoring and regular updates for us and responds very quickly to any issues or inquiries. They also configure new nodes, systems, and applications that we need to add to our cluster. With WZ-IT's proactive support, our cluster and the business-critical applications running on it remain stable, and high availability is consistently ensured. We value the professional collaboration and the noticeable relief it brings to our daily operations.”

“WZ-IT provided very competent support in implementing our server and virtualization infrastructure. As part of the project, a Proxmox-based virtualization environment was set up along with a virtual machine for our application systems. Additionally, a structured backup concept was implemented. A particular focus was on security: the setup of a VPN tunnel and the clean implementation of encryption and access concepts were professionally executed. The structured consulting as well as the reliable and swift implementation deserve special mention. We are very satisfied with the services provided and are happy to recommend WZ-IT.”

The team not only implemented our requirements but also thought along and proactively. Instead of just processing individual tasks, they provided us with well-founded explanations that strengthened our own understanding. WZ-IT took a lot of pressure off us with their structured approach - that was exactly what we needed and is the reason why we keep coming back. (translated)”

I particularly appreciate the clear communication, transparent pricing, and the comprehensive expertise that both bring to the table. Even after the setup, they take care of the maintenance, which frees up my time enormously and allows me to focus on other important areas of my business - with the good feeling that our IT is in the best hands. I can recommend WZ-IT without reservation and look forward to continuing our collaboration! (translated)”
