Data Limits in Matomo – No Limits

Note: The information in this page applies to you if you’re running Matomo On-Premise on your own servers or Matomo for WordPress.
If you are using the Matomo Cloud instead, there are limits enforced depending on which plan you’re using.
Quotas also can be lifted as required as part of the Enterprise plan.
Matomo Cloud also uses rate limiting on various resources to ensure the fair use of the platform.

Unlike many of our competitors in the analytics world that limit how you can capture and store your data, with Matomo On-Premise or Matomo for WordPress the main limits for you will be your server capabilities and hard disk space.

No Data Sampling

Matomo does not use data sampling on any analytics report. You always get to view the whole of your data and not a sampled data set.

Table Truncation

For performance reasons, Matomo will by default only archive the first 1,000 rows. You can easily edit the config file to enjoy non truncated reports and see 100% of your data. To do so read How can I force Matomo to not limit the data?

Data Storage and Data Collection Limits

There is no limit. You did not read this wrong. You can keep all your data forever.

By default, all historical visitor data, and all reports are kept. You can choose to anonymize the data or purge the old log or report data after a few months. It’s your decision as it is your data.

Also, we have added a new feature to make data storage management easier, by allowing you to easily delete older logs and reports. This is especially useful if you are using shared hosting, or have limited database space.

Raw data export

Other tools like Google Analytics often limit the access to event data (raw data), for example GA4 limits export of raw data to 1 million events per day into BigQuery. Matomo does not have any limit and 100% of your RAW data can be exported in full, for example into your data warehouse.

Tag Manager > Container size limit

There is no limit to the size of any container in the tag manager. There is also no limit to the number of containers, or the number of tags within a container.
