You added Mixpanel to your product eighteen months ago. It was the right call then: fast setup, clean funnels, a dashboard your whole team could actually read. Then your event volume grew, the invoice grew faster, and now you’re staring at a bill that costs more than the server your product runs on.
That’s the exact spot where most teams first hear about OpenPanel, an open-source analytics platform that tracks events, funnels, retention, and user sessions the way Mixpanel does, except you can run it on your own infrastructure for free. No per-event pricing that punishes growth. No third party holding your user data. No dashboard rebuild required, since the feature set overlaps with what you’re already used to.
This guide covers what OpenPanel actually is, how it’s built, what it costs on both the cloud and self-hosted paths, and where it beats (and loses to) the tools people usually compare it against. By the end you’ll know whether it fits your stack, and if it does, what running it on your own server actually involves.

TL;DR: OpenPanel in a Few Lines
Short on time? Here’s the whole guide condensed:
- OpenPanel is open-source web and product analytics, built to cover what Mixpanel does (funnels, cohorts, user profiles, session replay) with the simplicity of a tool like Plausible.
- It’s cookieless by default, which means most sites can skip the cookie consent banner entirely for analytics purposes.
- Self-hosting is free, full stop, under the AGPL-3.0 license. Cloud plans start at $2.50/month and scale with event volume.
- The stack runs on Next.js, Fastify, PostgreSQL, ClickHouse, and Redis, which is why self-hosting means running several containers, not a single binary.
- It has 6.8k GitHub stars and an active Discord, built originally by Swedish developer Carl Lindesvard.
- The name collides with an unrelated hosting control panel also called OpenPanel. They share nothing but a name. This guide is about the analytics tool.
- Self-hosting saves money but costs setup time. That trade-off is where a managed deployment path becomes worth knowing about, and we’ll get to that.
What Is OpenPanel, Exactly?
OpenPanel is an open-source analytics platform that tracks what happens on your website and inside your product: page views, custom events, user sessions, and the paths people take before they convert or churn. It’s built to replace two tools at once. Where Google Analytics or Plausible tell you traffic came from Twitter, and Mixpanel or Amplitude tell you what a logged-in user did once they arrived, OpenPanel does both from a single dashboard.
The project describes itself as combining Mixpanel’s depth with Plausible’s simplicity, and that’s a fair summary once you’ve used it. Funnels, cohorts, retention curves, and user profiles are all there, the way they are in Mixpanel. But the setup and the dashboard stay closer to the one-screen simplicity of a privacy-first tool like Plausible, rather than the more layered interface Mixpanel has accumulated over a decade of feature additions.
How OpenPanel Actually Works
A lightweight tracking script (about 2.3 KB) sits on your site or in your app and sends events to OpenPanel’s API. No cookies are set for this by default. Instead, OpenPanel uses fingerprinting techniques similar to Plausible’s approach to distinguish visitors without storing anything on their device. That’s also what lets most sites skip the cookie consent banner for analytics purposes, since there’s nothing being stored that requires consent under GDPR.
Events land in ClickHouse, a column-oriented database built for exactly this kind of high-volume, read-heavy analytics workload. That’s the same category of database Mixpanel and Amplitude run on internally. It’s a meaningful technical detail, because it means OpenPanel isn’t a lightweight side project bolted onto a relational database. It’s built on the same class of infrastructure the tools it competes with actually use.
Where OpenPanel Fits
If you’re currently running Google Analytics for marketing metrics and Mixpanel for product metrics, OpenPanel is trying to be the one tool that replaces both. That consolidation is the whole pitch: one dashboard, one SDK family, one bill (or no bill, if you self-host), instead of stitching two vendors together and reconciling numbers between them by hand.
OpenPanel vs Mixpanel: What Actually Changes
Mixpanel is the tool most people compare OpenPanel against, since OpenPanel was built specifically as an open-source alternative to it. Here’s where the two diverge.
| Factor | OpenPanel | Mixpanel |
|---|---|---|
| License | Open source (AGPL-3.0) | Proprietary |
| Self-hosting | Yes, free | No |
| Cookieless tracking | Yes, by default | No |
| Funnels & cohorts | Yes | Yes |
| Session replay | Yes, no session cap | Yes, capped at 5,000/month on free, 20,000 on paid |
| Pricing model | Flat tiers, $2.50–$90/month cloud, or free self-hosted | Usage-based, scales into hundreds or thousands per month at volume |
| Data location | Your server, or EU-hosted cloud | Mixpanel’s servers (US by default) |
| GDPR data processing agreement | Available | Available |
If you only remember one line from this table: Mixpanel charges by event volume, and OpenPanel doesn’t. That single difference is why most people go looking for a Mixpanel alternative in the first place. A growing product generates more events every month by definition, and Mixpanel’s pricing scales right alongside it. OpenPanel’s cloud tiers are flat, and self-hosting removes the event-volume question from the pricing conversation entirely.
The trade-off runs the other way on maturity. Mixpanel has been refining its analytics engine for over a decade, has deeper integrations with tools like Segment and Salesforce, and has enterprise features (advanced permissioning, SSO, dedicated support SLAs) that a newer open-source project hasn’t fully built out yet. If your team is 200 people deep into a Mixpanel workflow with custom integrations, the migration cost might outweigh the savings. If you’re a startup or an indie project watching your analytics bill outpace your hosting bill, the calculus flips.
OpenPanel vs Other Analytics Tools
Mixpanel isn’t the only tool people weigh OpenPanel against. Here’s how it stacks up against the other names that come up.
OpenPanel vs PostHog
PostHog is the closer competitor in scope. Both are open-source, both cover product analytics beyond simple pageviews, and both offer self-hosting. The difference is depth versus focus: PostHog has expanded into feature flags, A/B testing infrastructure, and session recording as a broader product suite, while OpenPanel stays concentrated on analytics itself. PostHog’s self-hosting path has also gotten more complicated over time. Full self-hosting is now largely community-maintained rather than officially supported, with some cloud-only features. OpenPanel’s self-hosted and cloud versions ship identical features, which matters if you’re choosing self-hosting specifically to avoid a two-tier product.
OpenPanel vs Plausible
Plausible is the simpler tool, deliberately. It’s a pageview-and-referrer dashboard, not a product analytics platform, and it doesn’t try to be one. If all you need is “how many visitors, where did they come from, what pages did they read,” Plausible is lighter and faster to learn. OpenPanel is the pick once you need to know what a logged-in user actually did, not just that they showed up.
OpenPanel vs Umami
Umami is the closest thing to a direct sibling: open-source, self-hostable, cookieless, and simple to deploy. The gap is the same one that separates OpenPanel from Plausible. Umami covers web analytics well but doesn’t reach into funnels, cohorts, or user-level product analytics the way OpenPanel does.
Is OpenPanel Free?
Yes, with a distinction worth understanding. Self-hosting OpenPanel is completely free under the AGPL-3.0 open-source license. You run it on your own server, pay nothing to OpenPanel, and there’s no artificial cap on events, users, or projects.
The hosted cloud version is a separate, paid product that OpenPanel operates for people who’d rather not manage servers. Cloud pricing starts at $2.50/month for up to 5,000 events and scales to $90/month at 1 million events, with every feature included at every tier rather than gated behind a higher plan. Both versions run the identical codebase, so you’re not sacrificing features by choosing the free path.
A Quick Word on the Name Collision
If you search “OpenPanel,” you’ll also find an unrelated product: a paid web hosting control panel, similar in spirit to cPanel or CyberPanel, used for managing shared hosting accounts and PHP environments. It has nothing to do with analytics, comes from a different company, and shares the name by coincidence rather than by any relationship.
This guide, and everything below it, is about the open-source analytics platform: the Mixpanel alternative built by Carl Lindesvard and maintained by the OpenPanel-dev organization on GitHub, currently sitting at 6.8k stars and 460 forks. If you landed here looking for a hosting control panel, this isn’t that tool.
What Self-Hosting OpenPanel Actually Involves
Here’s the part that trips people up. “Self-hosted” sounds like one server and a config file. OpenPanel’s actual stack is closer to a small application platform:
- Next.js dashboard
- Fastify event-tracking API
- PostgreSQL for accounts, organizations, and project configuration
- ClickHouse for the event data itself
- Redis for caching, pub/sub, and the job queue
- BullMQ for background processing
That’s seven containers running together, not one. The official self-hosting guide walks through a Docker Compose setup, and it’s genuinely well documented as these things go. But you’re still the one provisioning a server with enough headroom for PostgreSQL, ClickHouse, and Redis to run privately, wiring up a domain and HTTPS certificate for the dashboard and API, generating secrets, and setting a backup schedule that covers all three databases as one consistent set, since a backup of ClickHouse alone without PostgreSQL leaves you with events and no accounts to attach them to.
None of that is unusual for self-hosted infrastructure in general. It’s the same category of work covered in a guide to understanding Docker and its components, and it follows the same security basics as any other internet-facing service, covered in more depth in our guide to web hosting security best practices. It’s just more moving parts than a typical single-container app, which is exactly why some teams decide to hand the provisioning part to someone else and keep the “free and open source” part of the deal.
Deploying OpenPanel Without Assembling It by Hand
If the container count above sounds like more infrastructure work than you want to take on, that’s the gap OpenPanel Hosting on xCloud is built to close. It’s the same self-hosted OpenPanel, the same AGPL-3.0 open-source codebase, just deployed for you instead of assembled by hand.
What xCloud sets up automatically:
- The dashboard, API, and worker images, pinned to a specific OpenPanel version by immutable digest
- Private PostgreSQL, ClickHouse, and Redis services, kept off the public internet
- The cookie secret and database credentials, generated for you rather than typed into a
.envfile - HTTPS on your domain, with the certificate issued and renewed automatically
- All three persistent volumes, so your event history survives a restart
- Server-level backups and snapshots, so the coordinated-backup problem above isn’t something you have to design yourself
You still own the data. It’s still self-hosted, still open source, still yours to export or walk away from at any point. What changes is that you’re not the one keeping seven containers healthy at 11 p.m. when ClickHouse decides to misbehave.
If you’re already comfortable managing a server yourself, xCloud’s one-click app catalog covers nearly 300 other Docker-hosted apps the same way, and the platform’s Git-based deployment flow works well if you’re pairing OpenPanel with a Node.js app you’re also tracking events from.
Own Your Analytics Data This Week
The core decision is simpler than the feature comparison table makes it look. If you’re paying Mixpanel by the event and watching that number climb every quarter, OpenPanel gets you the same funnels and cohorts without the meter running. If you’re currently juggling Google Analytics and a separate product analytics tool, OpenPanel is a real case for consolidating into one dashboard and one SDK.
The only real question left is who manages the server. Self-hosting by hand is free and gives you full control, at the cost of your own time keeping PostgreSQL, ClickHouse, and Redis patched and backed up together. A managed path trades a monthly hosting fee for getting that time back. Neither answer is wrong. Pick based on whether your team’s hours or your team’s budget is the scarcer resource this quarter.

Frequently Asked Questions
Is OpenPanel really free?
Self-hosting is free under the AGPL-3.0 license, with no event caps or feature gates. OpenPanel’s cloud version is a separate paid product starting at $2.50/month, for teams that would rather not manage the server themselves.
Is OpenPanel the same as the hosted openpanel.dev service?
Not exactly. The self-hosted codebase and the hosted cloud service run the identical application, so you get the same features either way. The difference is only who operates the servers, not what the product does.
Does OpenPanel replace Google Analytics?
For most use cases, yes. OpenPanel covers pageviews, referrers, and traffic sources the way GA4 does, and adds funnels, cohorts, and user-level product analytics that GA4 doesn’t handle well without a BigQuery export. The main thing you’d lose is GA4’s specific ad-platform integrations if you rely on those.
Do I need to show a cookie consent banner with OpenPanel?
In most cases, no. OpenPanel doesn’t set tracking cookies by default, which means it typically falls outside the consent requirements that apply to cookie-based analytics under GDPR. Confirm this against your own legal requirements if you operate in a regulated industry or region.
What server size do I need to self-host OpenPanel?
The project’s own manifest asks for roughly 3 GB of RAM as a floor. In practice, seven containers with real event volume and ClickHouse retention want more headroom than that, which is why a 16 GB instance is a safer starting point than the bare minimum once you’re past a test install.
Can I migrate away from OpenPanel later if I need to?
Yes. Because it’s open source under AGPL-3.0, you can export your data, fork the codebase, or move to a different tool at any point. There’s no proprietary export format or vendor lock-in holding your event history hostage.
Is OpenPanel the same as the OpenPanel hosting control panel?
No, and this is a common mix-up. The analytics tool covered in this guide has nothing to do with the separately branded hosting control panel that manages shared hosting accounts. Different company, different product, same name by coincidence.
