Custom extensions, API integrations, and seamless embedding into your system landscape.
Standard software often covers 90% – we close the last gap. We develop Plugins, connect OpenProject 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.
OpenProject is powerful, but rarely alone in large corporations. We integrate it into your existing ERP and controlling landscape.
We use the API for bidirectional sync. Projects created in ERP -> automatically created in OpenProject. Times booked in OpenProject -> transferred to ERP.
Status changes drive processes. When a work package is set to 'Completed', we automatically inform the client or trigger invoicing.
We develop plugins that add new tabs to project views, provide specific export formats, or map complex approval workflows.
How we implement OpenProject development in practice.
Project managers plan in OpenProject, controllers need numbers in SAP CO. Manual transfer is error-prone.
Middleware that keeps cost centers and budgets in sync. Booked hours are transmitted to SAP nightly as activity allocation.
Standard status transitions (New -> In Progress) are insufficient. Conditional transitions are needed (e.g., four-eyes principle).
Development of workflow guards that block status changes if mandatory fields are missing or the user does not have the required role.
Management needs a one-pager project status that OpenProject does not export natively.
A custom reporting plugin that aggregates data and generates a management summary PDF that exactly matches your corporate design.
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.
