Coderz Stack

The Coderz Stack is a fully self-hosted, production-ready infrastructure platform running on a single server. It replaces multiple paid SaaS tools with open-source alternatives — delivering enterprise-level observability, logging, automation, and API management at a fraction of the cost.
Server IP: 109.199.120.120 — All services are containerized using Docker Compose.

​
What’s Inside

The stack is organized into 8 functional layers:

Monitoring

Grafana + Prometheus + Node Exporter + cAdvisor — real-time metrics for host, containers, and APIs.

Logging

Dual pipeline: Loki/Promtail for fast querying and ELK (Elasticsearch + Logstash + Kibana) for deep log analytics.

API Gateway

Nginx-based API Gateway with Redis caching and rate limiting — protecting and accelerating all backend APIs.

Orchestration

Prefect for scheduled workflows — health checks, daily reports, alerts, and cleanup jobs.

APIs

Python Web API (port 8888) and .NET API (port 5050) — both fully monitored and logged.

Database

PostgreSQL with pgAdmin — managed, backed, and monitored.

Load Testing

k6 with a web UI — run stress, spike, and ramp-up tests against any service.

Kubernetes

k3s lightweight Kubernetes cluster — deploy containerized workloads with full observability.
