Event Log — Open Source Self‑Hosted Event Analytics

Overview

This repository contains a high-performance, open-source infrastructure for collecting, processing, and visualizing event data in real time. The goal is a lightweight, modular self-hosted system that gives developers full control over their data.

Architecture (short)

• apps/web — Next.js based dashboard (frontend)
• apps/server — Java / Gradle backend (API, event engine)

Configuration

# Create initial configuration (only if no configuration exists yet)
./scripts/generate_config.sh

# Keep existing configuration and fill in missing values
./scripts/update_config.sh

# Reset configuration to default values
./scripts/reset_config.sh

Docker

# Danach den Stack starten
docker compose up -d

The generated .env file contains the same values as eventlog.conf and is used by docker-compose.yml.

If you like, I can add pnpm workspace and CI setups, as well as base configs for linters and editors.
