## Introduction
OpenPanel combines web analytics and product analytics into a single open-source platform. It tracks page views, custom events, user journeys, and funnels while keeping data under your control, providing a self-hostable alternative to commercial tools like Mixpanel and Amplitude.

## What OpenPanel Does
- Tracks page views, sessions, and custom events with automatic property capture
- Provides funnel analysis and user journey visualization
- Offers real-time dashboards with filtering by any event property
- Supports both web and mobile SDKs for cross-platform tracking
- Includes a lightweight script (less than 1KB) for minimal performance impact

## Architecture Overview
OpenPanel uses a TypeScript/Next.js frontend with a backend that ingests events via a REST API. Event data is stored in ClickHouse for fast analytical queries. PostgreSQL handles metadata like project settings and user accounts. The ingestion pipeline processes events asynchronously for high throughput.

## Self-Hosting & Configuration
- Deploy via Docker Compose with ClickHouse, PostgreSQL, and Redis included
- Configure the .env file for database credentials, domain, and SMTP settings
- Place behind a reverse proxy (Nginx, Caddy) for TLS and custom domain support
- Data retention policies are configurable to manage storage costs
- Supports sending email reports via configured SMTP server

## Key Features
- Unified web and product analytics in one dashboard
- Privacy-friendly with cookie-free tracking option
- Real-time event stream for debugging integrations
- Customizable dashboards with saved filters and date ranges
- Export capabilities for raw event data analysis

## FAQ
**Q: How does OpenPanel handle GDPR compliance?**
A: Self-hosting means data stays on your infrastructure. The cookie-free mode tracks sessions without storing personal identifiers.

**Q: What is the tracking script size?**
A: The web SDK is under 1KB gzipped, designed to have no measurable impact on page load times.

**Q: Can I import data from Google Analytics?**

**Q: Does it support server-side event tracking?**
A: Yes, the REST API accepts events from any backend, enabling server-side tracking alongside the client SDK.
