Summary

Helion is an open-source product and web analytics platform for tracking user behavior, events, funnels, retention and web traffic. It brings together event tracking, user profiles, cohort analysis, real-time dashboards, session replay, A/B testing and revenue tracking. An MCP server lets compatible AI clients such as Claude and Cursor query analytics data, while ClickHouse stores events and runs analytics queries. Teams can route event-triggered notifications to Slack, Discord or a custom webhook, with JavaScript payload transforms. Tracking is cookieless by default and does not require third-party tracking cookies. Session replay is optional, off by default and retained for 30 days. Helion supports SDKs including JavaScript, React, Next.js, Astro and Python, and is available across web, mobile, desktop, API and self-hosted platforms. Self-hosting is supported through Docker Compose on a VPS, Kubernetes cluster or cloud provider; that software is AGPL-3.0 licensed. The self-hosted plan costs 0.00 USD per free with unlimited events and all features. Helion Cloud costs 90.00 USD per month for 1M events and all features.
