Custom extensions, API integrations, and seamless embedding into your system landscape.
Standard software often covers 90% – we close the last gap. We develop Plugins & Bots, connect Mattermost with your tools, and automate workflows.
From API integration to complete custom solutions – we cover the entire spectrum.
We make your systems talk to each other. Whether REST, GraphQL, or webhooks – we connect software with your CRM, ERP, or identity provider.
Often data formats from System A don't match System B. We develop middleware that sits in between, transforms data, and controls processes.
Want to use software features in your own intranet or customer portal? We embed software headlessly and build custom UIs around it.
Save manual work through intelligent automation. We develop bots and scripts that handle tasks automatically.
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.
Update-safe, scalable, and secure – why you should trust us with your development.
We don't modify the open-source software's source code. Instead, we use official APIs and plugin architectures. Your installation remains updatable and maintainable.
We understand not just the code, but the infrastructure beneath it. Our developers know how queries affect database performance and how to build scalable APIs.
We use modern, type-safe technologies: React, TypeScript, Node.js, Python, Go. Plus PostgreSQL, Redis, and Docker/Kubernetes for infrastructure.
Every line of code is written with security in mind. Input sanitization, secure authentication (OAuth2/OIDC), and compliance with data protection regulations are standard.
