GitLab Development & Integration
Custom extensions, API integrations, and seamless embedding into your system landscape.
Standard software often covers 90% – we close the last gap. We develop Integrations, connect GitLab with your tools, and automate workflows.
Our Development Services
From API integration to complete custom solutions – we cover the entire spectrum.
API & Interface Integration
We make your systems talk to each other. Whether REST, GraphQL, or webhooks – we connect software with your CRM, ERP, or identity provider.
- Bidirectional data synchronization
- Third-party system connections
- Custom webhooks & event handlers
- Legacy system integrations
Custom Middleware & Logic
Often data formats from System A don't match System B. We develop middleware that sits in between, transforms data, and controls processes.
- Transformation layer (ETL)
- Data stream validation
- Caching layer for performance
- Microservices architecture
Embeddings & Custom Apps
Want to use software features in your own intranet or customer portal? We embed software headlessly and build custom UIs around it.
- White-label integration
- Custom dashboards (React/Vue)
- UI extension via plugins
- Mobile app customizations
Automation & Bots
Save manual work through intelligent automation. We develop bots and scripts that handle tasks automatically.
- ChatOps & slash commands
- Automated reporting
- Workflow orchestration
- Trigger-based actions
GraphQL Power & Pipeline Integration
GitLab is more than a Git repository – it's a complete DevSecOps platform. The powerful GraphQL API and event system make it an ideal candidate for deep integrations.
REST & GraphQL API
GitLab offers a powerful GraphQL API that enables precise data queries without over-fetching. Particularly performant for custom dashboards that display the status of hundreds of pipelines, issues, or merge requests in aggregate.
Webhooks & System Hooks
GitLab fires events for almost everything: push, merge request, pipeline failure, issue update. We develop middleware that receives these hooks and controls your processes – automatic ticket creation in Jira, deployment triggering, or compliance notifications.
CI/CD & Runner Integration
The strength lies in CI/CD. Instead of UI plugins, we develop custom executor scripts or containers for GitLab Runners. Compliance checks, security scans (SAST, DAST), license audits, or deployment logic are integrated directly into your build pipelines.
Concrete Use Cases
How we implement GitLab development in practice.
CI/CD Pipeline Extensions
Standard CI/CD templates don't cover your specific requirements: custom compliance checks, internal security tools, or proprietary deployment targets.
We develop custom CI/CD components and container images for your GitLab Runners. These execute your specific checks (SBOM generation, license compliance, custom SAST) and integrate seamlessly into existing pipelines.
Issue Tracker Synchronization
Developers work in GitLab Issues, but project management uses Jira/Asana/Linear. Double data maintenance and sync problems are the result.
Bidirectional synchronization via webhooks and APIs. Status updates, comments, and attachments are automatically mirrored. Merge request links appear in the external tool, issue IDs are referenced in commits.
Compliance & Audit Dashboard
For audits, information from various GitLab projects must be manually compiled: Who merged what when? Which pipelines failed?
A custom dashboard aggregates data via GraphQL API: merge request approvals, pipeline success rates, deployment history. Export functions for PDF reports and automatic alerts for policy violations included.
Development with Foresight
Update-safe, scalable, and secure – why you should trust us with your development.
Update-safe (No Core Hacking)
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.
Full-Stack Expertise
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.
Modern Tech Stack
We use modern, type-safe technologies: React, TypeScript, Node.js, Python, Go. Plus PostgreSQL, Redis, and Docker/Kubernetes for infrastructure.
Security by Design
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
How We Work
From requirements to go-live – transparent and structured.
Analysis
We review API documentation, analyze your requirements, and identify optimal integration points.
Architecture
We design the solution: middleware, plugin, or script. Data flows, interfaces, and security concept are defined.
Development
Agile implementation with code reviews, automated tests, and continuous coordination. You see progress in real-time.
Deployment
Integration into your CI/CD pipeline or hosting on our infrastructure. Documentation and training included.
