Kleff is an open-source hosting platform designed to make server deployment simple, powerful, and developer-friendly.
Inspired by Pterodactyl and Vercel, Kleff provides a modular API-driven ecosystem for hosting both web and game servers — built entirely around clean architecture and modern DevOps principles.
Whether you’re running a Minecraft server, deploying a full-stack web app, or managing CI/CD pipelines, Kleff gives you full control over your infrastructure — locally or in the cloud.
Kleff is composed of microservices that work together seamlessly:
| Service | Description |
|---|---|
| Auth Service | Handles authentication, JWT sessions, and secure token management. |
| Container Service | Manages lifecycle of Docker containers (create, start, stop, restart, delete). |
| API Gateway | Entry point for all client and SDK interactions. |
| Frontend Dashboard | Modern UI for developers to deploy and monitor servers. |
| Metrics & Monitoring | Integration with Prometheus and Grafana for live server stats. |
Each service is containerized and built for horizontal scalability — perfect for distributed hosting setups.
- Go — backend services & API gateway
- TypeScript / React — frontend dashboard
- Docker — container orchestration
- PostgreSQL / MongoDB — persistent data storage
- Nginx / BunkerWeb — reverse proxy layer
- Prometheus / Grafana — observability & metrics
Kleff’s mission is to empower developers to self-host without compromise.
We believe in open systems, transparent architecture, and community-driven innovation.
All core components of Kleff are open-sourced — from the API to the deployment engine — to encourage contributions, learning, and customization.
