Fathom Lite. Simple, privacy-focused website analytics. Built with Golang & Preact.

Quick Overview

Plausible Analytics is an open-source, lightweight, and privacy-friendly alternative to Google Analytics. It provides simple and easy-to-understand website analytics without using cookies and fully compliant with GDPR, CCPA, and PECR. The project aims to offer a more ethical approach to tracking website visitors while still providing valuable insights.

Pros

Privacy-focused: Does not use cookies or collect personal data
Lightweight: Weighs less than 1KB, having minimal impact on website performance
Simple and intuitive dashboard: Easy to understand analytics without complex metrics
Self-hostable: Can be deployed on your own infrastructure for complete data control

Cons

Less detailed data compared to Google Analytics
Limited integrations with other tools and platforms
Fewer advanced features for in-depth analysis
Requires self-hosting or paid subscription for use, unlike free alternatives

Getting Started

To get started with Plausible Analytics, follow these steps:

Sign up for an account at https://plausible.io/ or self-host the application
Add your website to the Plausible dashboard
Add the following script to your website's HTML, replacing yourdomain.com with your actual domain:

<script defer data-domain="yourdomain.com" src="https://plausible.io/js/plausible.js"></script>

Wait for data to start appearing in your Plausible dashboard (usually within 24 hours)

For self-hosting instructions, refer to the official documentation: https://plausible.io/docs/self-hosting

Competitor Comparisons

matomo

posthog.init('YOUR_PROJECT_API_KEY', {api_host: 'https://app.posthog.com'})

Plausible (JavaScript snippet):

<script defer data-domain="yourdomain.com" src="https://plausible.io/js/plausible.js"></script>

The code comparison shows that PostHog's implementation is more complex and customizable, while Plausible offers a simpler, more lightweight integration.

umami

37,631

Umami is a modern, privacy-focused analytics platform. An open-source alternative to Google Analytics, Mixpanel and Amplitude.

Pros of Umami

Self-hosted and completely free, offering full control over data
Simpler setup process, especially for users familiar with Node.js
More customizable dashboard with additional metrics and chart options

Cons of Umami

Less polished UI compared to Plausible's clean and modern interface
Fewer built-in features for advanced analytics (e.g., custom events, goals)
Smaller community and ecosystem, potentially leading to slower development and fewer integrations

Code Comparison

Umami (JavaScript):

export async function savePageView(website_id, data) {
  const { url, referrer, browser, os, device, screen } = data;
  const [pageView] = await db.transaction(async () => {
    // ... (implementation details)
  });
  return pageView;
}

Plausible (Elixir):

def insert(site, attrs) do
  params = Map.merge(attrs, %{
    "hostname" => URI.parse(attrs["pathname"]).host,
    "site_id" => site.id,
    "timestamp" => NaiveDateTime.utc_now() |> NaiveDateTime.truncate(:second)
  })
  %Pageview{}
  |> cast(params, [:hostname, :pathname, :referrer, :user_agent, :screen_size, :country_code, :operating_system, :browser, :site_id, :timestamp])
  |> validate_required([:hostname, :pathname, :timestamp, :site_id])
  |> foreign_key_constraint(:site_id)
  |> Repo.insert()
end

Both projects implement similar functionality for saving page views, but Umami uses JavaScript with async/await, while Plausible uses Elixir with a more functional approach.

func (s *SQLStore) GetSiteStats(siteID int64, startDate time.Time, endDate time.Time) (*models.SiteStats, error) {
    var stats models.SiteStats
    err := s.db.Get(&stats, `
        SELECT
            COUNT(DISTINCT(pageviews.visitor_id)) as visitors,
            COUNT(*) as pageviews,
            COUNT(DISTINCT(pageviews.hostname || pageviews.pathname)) as pages
        FROM pageviews
        WHERE site_id = $1 AND timestamp >= $2 AND timestamp <= $3
    `, siteID, startDate, endDate)
    return &stats, err
}

Plausible (Elixir):

def aggregate(site, query) do
  from(e in base_query(site, query),
    select: %{
      visitors: fragment("COUNT(DISTINCT visitor_id)"),
      pageviews: fragment("COUNT(*)"),
      bounce_rate: fragment("ROUND(100 * SUM(CASE WHEN sign = -1 THEN 1 ELSE 0 END)::float / COUNT(DISTINCT visitor_id), 1)"),
      visit_duration: fragment("ROUND(AVG(duration::float), 2)")
    }
  )
  |> Repo.one()
end

Both repositories implement analytics data aggregation, but use different programming languages and database query approaches.

We are dedicated to making web analytics more privacy-friendly. Our mission is to reduce corporate surveillance by providing an alternative web analytics tool which doesnât come from the AdTech world. We are completely independent and solely funded by our subscribers.

Interested to learn more? Read more on our website, learn more about the team and our goals on our about page or explore the documentation.

Why is Plausible Analytics Cloud not free like Google Analytics?

Plausible is an independent, open source project funded entirely by our users. We charge a subscription to sustainably develop, maintain and improve the product over the long term.

Google Analytics is free to use because Google monetizes user data for advertising. That model comes with trade-offs: data collection, complexity and additional overhead for compliance and consent.

With Plausible, the business model is simple:

No data collection beyond aggregated, anonymized stats
No third-party data sharing
No advertising or tracking ecosystem
You fully own and control your data

We believe paying for analytics should be straightforward. You pay for a product, not with your usersâ data, but with a transparent subscription. Learn more.

Getting started with Plausible

The easiest way to get started with Plausible Analytics is with our official managed service in the cloud.

Takes ~2 minutes to set up
Global CDN, high availability, backups and security included
No maintenance required

In order to be compliant with the GDPR and the Schrems II ruling, all visitor data for our managed service in the cloud is exclusively processed on servers and cloud infrastructure owned and operated by European providers. Your website data never leaves the EU.

Our managed hosting can save a substantial amount of developer time and resources. For most sites this ends up being the best value option and the revenue goes to funding the maintenance and further development of Plausible. So youâll be supporting open source software and getting a great service!

Can Plausible be self-hosted?

Plausible is open source web analytics and we have a free as in beer and self-hosted solution called Plausible Community Edition (CE). Here are the differences between Plausible Analytics managed hosting in the cloud and the Plausible CE:

	Plausible Analytics Cloud	Plausible Community Edition
Infrastructure management	Easy and convenient. It takes 2 minutes to start counting your stats with a worldwide CDN, high availability, backups, security and maintenance all done for you by us. We manage everything so you donât have to worry about anything and can focus on your stats.	You do it all yourself. You need to get a server and you need to manage your infrastructure. You are responsible for installation, maintenance, upgrades, server capacity, uptime, backup, security, stability, consistency, loading time and so on.
Release schedule	Continuously developed and improved with new features and updates multiple times per week.	It's a long term release published twice per year so latest features and improvements won't be immediately available.
Premium features	All features available as listed in our pricing plans.	Premium features (marketing funnels, ecommerce revenue goals, SSO and sites API) are not available in order to help support the project's long-term sustainability.
Bot filtering	Advanced bot filtering for more accurate stats. Our algorithm detects and excludes non-human traffic patterns. We also exclude known bots by the User-Agent header and filter out traffic from data centers and referrer spam domains. We exclude ~32K data center IP ranges (i.e. a lot of bot IP addresses) by default.	Basic bot filtering that targets the most common non-human traffic based on the User-Agent header and referrer spam domains.
Server location	All visitor data is exclusively processed on EU-owned cloud infrastructure. We keep your site data on a secure, encrypted and green energy powered server in Germany. This ensures that your site data is protected by the strict European Union data privacy laws and ensures compliance with GDPR. Your website data never leaves the EU.	You have full control and can host your instance on any server in any country that you wish. Host it on a server in your basement or host it with any cloud provider wherever you want, even those that are not GDPR compliant.
Data portability	You see all your site stats and metrics on our modern-looking, simple to use and fast loading dashboard. You can only see the stats aggregated in the dashboard. You can download the stats using the CSV export, stats API or the Looker Studio Connector.	Do you want access to the raw data? Self-hosting gives you that option. You can take the data directly from the ClickHouse database. The Looker Studio Connector is not available.
Premium support	Real support delivered by real human beings who build and maintain Plausible.	Premium support is not included. CE is community supported only.
Costs	There's a cost associated with providing an analytics service so we charge a subscription fee. We choose the subscription business model rather than the business model of surveillance capitalism. Your money funds further development of Plausible.	You need to pay for your server, CDN, backups and whatever other cost there is associated with running the infrastructure. You never have to pay any fees to us. Your money goes to 3rd party companies with no connection to us.

Interested in self-hosting Plausible CE on your server? Take a look at our Plausible CE installation instructions.

Plausible CE is a community supported project and there are no guarantees that you will get support from the creators of Plausible to troubleshoot your self-hosting issues. There is a community supported forum where you can ask for help.

Our only source of funding is our premium, managed service for running Plausible in the cloud.

Technology

Plausible is built with a modern, scalable stack:

Backend: Elixir + Phoenix
Databases: PostgreSQL (general data), ClickHouse (analytics)
Frontend: React + TailwindCSS

Our architecture allows Plausible to handle large volumes of traffic efficiently while keeping the dashboard fast and responsive.
