OpenPanel Review
Open-source product and web analytics with self-hosting, MCP integration, and Mixpanel-level event depth
OpenPanel is a compelling open-source alternative to Mixpanel and Google Analytics that you can self-host for full data ownership or use on a cloud plan starting at $2.50/month. The feature depth is genuine: custom events, funnels, A/B testing, revenue tracking, and 38 MCP tools for AI agent integration. The trade-off is that setup and maintenance require more technical confidence than SaaS-only competitors.
Pros and cons
- Open-source with self-hosting option for complete data ownership
- Event-based pricing starting at $2.50/month for 5K events, scales predictably
- Custom event tracking, funnels, A/B testing, and revenue tracking in one platform
- 38 MCP tools for connecting OpenPanel data to AI agents
- Privacy-first tracking without cookies on a hosted plan that handles compliance
- Self-hosting requires technical setup and ongoing infrastructure maintenance
- No white-label delivery for agencies managing client analytics
- Smaller community and ecosystem than Mixpanel or Google Analytics
What is OpenPanel?
OpenPanel is an open-source analytics platform that combines product analytics and web analytics in a single tool. It is positioned as an alternative to Mixpanel for event tracking and Google Analytics for web traffic, with the option to run the entire stack on your own infrastructure. The cloud-hosted version starts at $2.50/month for 5,000 events, making it accessible well below the price point of most product analytics tools.
The platform covers custom event tracking, user flow analysis, funnel conversion, A/B testing, and revenue tracking. Privacy-first tracking is built in: no cookies are required on the hosted plan, and self-hosters have complete control over where data is stored and how long it is retained. For teams with regulatory requirements around data residency, self-hosting removes the dependency on a third-party cloud entirely.
A notable differentiator is the integration with AI agents via 38 MCP (Model Context Protocol) tools. This lets AI agents query OpenPanel data, trigger event tracking, and incorporate analytics context into automated workflows. For teams building AI-assisted products or using agent frameworks like Claude Code, this is an unusual capability that most analytics platforms do not offer.
Core features
Self-hosting with full data ownership
OpenPanel can be deployed on your own infrastructure, giving you complete control over where analytics data lives, how long it is retained, and who can access it. This is the primary reason teams choose OpenPanel over cloud-only alternatives: for GDPR Article 28 compliance, data residency requirements, or simply not wanting to send behavioral data to a third party. The open-source codebase means you can inspect, audit, and modify the tracking logic itself.
Custom event tracking and user flow analysis
OpenPanel tracks arbitrary custom events across your product and website, building session timelines that show how individual users or cohorts move through your application. Funnel analysis lets you define multi-step conversion paths and filter by any event property to identify where drop-offs occur. This puts it in the same functional category as Mixpanel or Amplitude, at a fraction of the cost on the cloud plan.
A/B testing and revenue tracking
Split testing is built into OpenPanel, so you can run experiments and measure results against event-based conversion metrics without a separate tool. Revenue tracking connects to subscription and purchase events, giving you a picture of which traffic sources, experiments, or user segments drive actual revenue rather than just engagement metrics.
38 MCP tools for AI agent integration
OpenPanel exposes 38 Model Context Protocol tools that allow AI agents to query analytics data, retrieve event counts, pull user segment summaries, and incorporate OpenPanel context into agent-driven workflows. This is uncommon in the analytics market and is specifically valuable for teams using agent frameworks like Claude Code, Cursor, or custom LLM pipelines where analytics context should inform automated decisions.
Privacy-first tracking without cookies
On both the cloud and self-hosted plans, OpenPanel tracks visitors and events without third-party cookies. This keeps you compliant with GDPR and CCPA without needing to implement a consent management platform for the analytics layer. For self-hosters, first-party data stays entirely within your own infrastructure with no data leaving your environment.

Who it is for
Needs Mixpanel-level event tracking at a price that makes sense before product-market fit. OpenPanel gives you funnels, user flows, and revenue tracking from $2.50/month, and the self-hosting option means you never have a surprise bill when your event volume spikes.
Operating under data residency requirements or internal policies that prohibit sending behavioral data to third-party SaaS platforms. Self-hosting OpenPanel keeps all analytics data on your own infrastructure while still delivering product analytics depth equivalent to commercial tools.
Building products or workflows that involve AI agents. The 38 MCP tools mean your AI agents can query product analytics data directly, surface insights, or trigger actions based on event patterns without manual data export steps.
Verdict
OpenPanel delivers genuine product analytics depth at a price point that makes it the strongest value option in the self-hosted and low-cost cloud analytics space. The MCP integration is a meaningful differentiator for teams building AI-driven workflows. The limitation is that it asks more of you technically than Mixpanel or Amplitude: self-hosting has real maintenance overhead, and the cloud plan, while cheap, has a smaller support ecosystem behind it. For technical teams that can handle the setup, this is a hard tool to beat on price-to-capability ratio.
Frequently asked questions
Is OpenPanel truly open-source?
Yes. OpenPanel is open-source and the codebase is available on GitHub. You can self-host the entire platform on your own infrastructure, inspect the tracking code, and modify it to meet your requirements. The cloud plan is a managed version of the same codebase.
How does OpenPanel pricing work?
Cloud plans are priced per monthly event volume, starting at $2.50/month for 5,000 events. An event is any tracked action: a pageview, a custom event, a user sign-up, or a purchase. Self-hosting is free, though you pay for your own infrastructure. There is no per-seat pricing.
What are the 38 MCP tools used for?
The MCP (Model Context Protocol) tools expose OpenPanel data to AI agents. This means an AI agent running in Claude Code, Cursor, or a custom LLM pipeline can query your event counts, pull user segment data, or retrieve funnel metrics as part of an automated workflow. It is most useful for teams where AI agents need analytics context to make decisions.
Can OpenPanel replace Google Analytics?
For web analytics use cases, yes, with the understanding that OpenPanel provides more event-tracking depth than GA4 in some areas while lacking GA4's integration with Google Ads and Search Console. For pure web traffic reporting, it covers pages, referrers, devices, and geography alongside custom event data.
Does OpenPanel offer white-label or agency features?
OpenPanel does not have built-in white-label delivery features. Agencies managing analytics for multiple clients typically either create separate projects per client on the cloud plan or self-host a shared instance. There is no branded client portal equivalent to what Simple Analytics or AI Peekaboo offer.
