Custom extensions, API integrations, and seamless embedding into your system landscape.
Standard software often covers 90% – we close the last gap. We develop Prosody Modules, connect Jitsi 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.
Jitsi is more than a video solution – it's a framework. The combination of IFrame API for frontend integration and Prosody (XMPP) for backend logic enables deep customization.
For frontend integrations, we use the IFrame API. We control the meeting from outside: mute/unmute, layout changes, participant management from your web app.
In the backend (XMPP server), we use Lua hooks to deeply intervene in session logic. Authentication, room creation, or recording control happens here.
For mobile apps, we use the SDK to seamlessly integrate Jitsi into your iOS/Android app – without the user noticing they're using external technology.
How we implement Jitsi development in practice.
Patients should not need an account and only enter when the doctor is ready.
We implement 'lobby' logic via JWT token. The patient waits in a digital waiting room (your web app) and is only admitted via API when the doctor clicks.
Jitsi should only be accessible to employees with existing company login.
A custom Prosody module validates your internal session tokens or checks against an external database whether the user has permission for this specific room.
Meetings must be recorded and archived for compliance.
We control Jibri (recording service) programmatically. Recordings are automatically started, tagged with metadata, and moved directly to your S3 storage/Nextcloud after ending.
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.
