Description
Companies want to understand how people actually use their product — which features get used, where users drop off, whether a change increased revenue — without either building this from scratch or handing all their user data to a big analytics vendor. OpenPanel is a free, open tool that gives a team this kind of insight while keeping the data on infrastructure they control.
OpenPanel is an open-source analytics platform that combines product analytics (in the style of Mixpanel), privacy-first web analytics (like Plausible) and traffic analysis (like Google Analytics) in one tool. Client SDKs and a server-side API send events into a real-time engine, which powers dashboards covering funnels, user cohorts, individual user profiles, session replay, retention curves (day 1/7/30), revenue and MRR tracking, and A/B testing. It supports GDPR-compliant cookieless tracking, exposes a REST API for raw data access, and — notably for 2026 — ships an MCP server so AI coding assistants like Claude, Cursor and Windsurf can query analytics data directly. The core is AGPL-3.0 and free to self-host with unlimited events; the hosted cloud starts around $20/month with a pay-per-event model beyond a free allotment.
💬 Our review
The short version: if you want Mixpanel-grade product analytics without Mixpanel-grade pricing or a giant vendor holding your user data, OpenPanel's free self-hosted option is a genuinely strong deal.
OpenPanel's pitch — one tool instead of stitching Plausible (privacy) plus Mixpanel (product analytics) plus a BI dashboard — is ambitious but the feature list backs it up: funnels, cohorts, session replay and revenue tracking are usually split across multiple paid tools. Self-hosting with unlimited events at zero license cost is the standout value proposition versus Mixpanel, whose usage-based pricing gets expensive fast at scale. The MCP integration is a smart, timely addition — letting an AI coding assistant pull real product-usage data during development is genuinely useful, not just a buzzword feature. The AGPL-3.0 license is worth knowing: it's more restrictive than MIT/Apache for anyone embedding OpenPanel inside a product they distribute (copyleft obligations kick in), though for internal analytics use that's irrelevant. As a younger project (no long public track record cited), expect some rough edges compared to Mixpanel's decade-plus of polish; but for a team willing to self-host and comfortable with AGPL, it's hard to beat on features-per-dollar.
