Custom extensions, API integrations, and seamless embedding into your system landscape.
Standard software often covers 90% – we close the last gap. We develop Rocket.Chat Apps, connect Rocket.Chat 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.
Rocket.Chat combines classic REST API with a powerful Apps-Engine. This allows us to deeply intervene in the message flow and build integrations that feel like native features.
Full access to users, channels, and messages. We use the Realtime API (WebSocket) for bots that react instantly, and REST for batch operations like user sync.
The Rocket.Chat Apps-Engine allows intercepting events (PreMessageSent, PostUserCreated). We modify messages on-the-fly or prevent actions based on compliance rules.
We develop native Rocket.Chat apps in TypeScript. These run isolated in the Rocket.Chat sandbox, are update-safe, and can render UI elements like buttons or modals.
How we implement Rocket.Chat development in practice.
Standard routing for WhatsApp/Livechat isn't enough. VIP customers should be routed directly to key account managers.
A custom app checks the phone number in CRM (Salesforce/HubSpot) on message arrival and routes the chat directly to the assigned advisor.
Employees must leave the chat window and switch to HR tool for vacation requests.
A bot posts an interactive form directly in chat. The employee clicks, fills out, and the app sends the data to the HR backend.
Sensitive data (credit card numbers, passwords) must never end up in chat history.
A pre-message hook scans every message before saving via RegEx or AI. Critical content is masked or sending is blocked with a warning.
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.
Our Tech Stack
From requirements to go-live – transparent and structured.
We review API documentation, analyze your requirements, and identify optimal integration points.
We design the solution: middleware, plugin, or script. Data flows, interfaces, and security concept are defined.
Agile implementation with code reviews, automated tests, and continuous coordination. You see progress in real-time.
Integration into your CI/CD pipeline or hosting on our infrastructure. Documentation and training included.
Let's get technical. We'll assess feasibility and effort.
