Koko Analytics


Koko Analytics is a privacy-friendly, simple and lightweight analytics plugin for WordPress. It does not use any external services, so data about your visitors is never shared with any third-party.
No visitor specific data is collected, only aggregated counts.

Stop sharing visitor data with third-party companies who also happen to sell ads.

Stop unnecessarily slowing down your website.

Koko Analytics lets you focus on the important metrics, while respecting the privacy of your visitors.


  • Plug and play: After installing and activating the plugin, stats will automatically be collected.
  • No external services: Any data never leaves your server.
  • No personal data or anything visitor specific is tracked.
  • No cookies: There is an option to not use any cookies.
  • Fast: Handles hundreds of concurrent pageviews without breaking a sweat.
  • Lightweight: Adds less than 850 bytes of data to your pages. A year worth of data will take up less than 10 MB of storage.
  • GDPR: Compliant by design.
  • Metrics: All the essentials: total pageviews, unique pageviews and referral URL’s.
  • Referrer spam: Built-in blocklist to filter out referrer spam.
  • Cached: Fully compatible with pages served from any kind of cache.
  • Open-Source: The plugin code is open-sourced under the GPL-3.0-or-later license.
  • Tested: Ready for PHP 8.3, but compatible down to PHP 7.3.
  • AMP: Tracks AMP powered pages too (official AMP plugin only).
  • Event Tracking: You can set up custom event tracking through Koko Analytics Pro.


You can contribute to Koko Analytics in many different ways. For example:


  • Koko Analytics’ dashboard to view your website statistics.
  • The settings page where you can exclude certain user roles from being counted.
  • A widget to show your most viewed posts (or any other post type) for a given period.
  • The dashboard widget to quickly show your site visits over the last 2 weeks.


You can install Koko Analytics in multiple ways:

After installing and then activating the plugin, statistics will be collected right away.

You can view your analytics dashboard by going to WP Admin > Dashboard > Analytics.


Does this respect my visitor’s privacy?

Yes, absolutely. Koko Analytics only stores aggregated counts. Nothing visitor specific is tracked.

Does this use any external services?

No external servives are used. All data lives on your server alone.

Does Koko Analytics set any cookies?

By default yes, but you can disable it.

Koko Analytics sets a single cookie named _koko_analytics_pages_viewed with a lifetime of 6 hours. This cookie is used to reliably detect unique pageviews and returning visitors without having to store any personal information on your server.

You can disable the use of cookies from the plugin’s settings page.


Will this slow down my website?

No, the plugin is built in such a way that it never slows down your website for your visitors.

  • It only adds a single script of less than 800 bytes to your pages.
  • All heavy lifting (like aggregating the statistics) is done in a background process.
  • Everything lives on your server, so the plugin doesn’t add any additional DNS look-ups and can benefit from your server’s cache policy.


Is the code for this plugin on GitHub?

Yes, see github.com/ibericode/koko-analytics.

Where can I find more documentation?

Have a look at the Koko Analytics knowledge base.

How to show number of visits to a page?

You can use the [koko_analytics_counter] shortcode to show the number of visitors to the current page.

It takes 3 optional arguments:

  • days: Show count over the last N days. Defaults to “3650”.
  • global: Whether to show the global count (for the entire site) or for the current page only. Defaults to “false”.
  • metric: One of “visitors” or “pageviews”. Defaults to “visitors”.

Example use with arguments:

[koko_analytics_counter days="30" metric="pageviews" global="true"]

How can I help fund Koko Analytics?

You can purchase Koko Analytics Pro to help fund the plugin.

You don’t need anything else. Would be great if I could import Jetpack data into it.

Koko Analytics ist das beste Plugin für datenschutzfreundliche Analysen. Der Support ist sehr gut, er hat schon mehrfach meine Verbesserungsvorschläge umgesetzt. Vielen Dank dafür.
Muzigo 31, 2024
Full-blown analytics solutions, like Google Analytics and Matomo (which are great, don’t get me wrong), are very, almost always, way overkill for the typical user. Lots and lots of data are collected, typically requiring cookie consent, and takes some effort to maintain and analyze if it’s supposed to have any value. Koko is the complete opposite. Close to no settings, not a burden on the client, no (optional) cookies, easy for the users to digest — is my site being visited, yes, keep up the good work creating good content. It’s not much, but it’s so much more than nothing. Absolutely a fine starting point for most analytics needs.

Tried other stats / analytics plugins, but some don’t show all the visits. Or show too much info you don’t use. Koko Analytics is easy to use and seems to work better then others. Used Jetpack stats before and this is a good replacement.
