+# Product Analytics **(CORE)**
+
+> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/225167) in GitLab 13.3.
+> - It's deployed behind a feature flag, disabled by default.
+> - It's disabled on GitLab.com.
+> - It's able to be enabled or disabled per-project.
+> - It's not recommended for production use.
+> - To use it in GitLab self-managed instances, ask a GitLab administrator to enable it.
+
+GitLab allows you to go from planning an application to getting feedback. Feedback
+is not just observability, but also knowing how people use your product.
+Product Analytics uses events sent from your application to know how they are using it.
+It's based on [Snowplow](https://github.com/snowplow/snowplow), the best open-source
+event tracker. With Product Analytics, you can receive and analyze the Snowplow data
+inside GitLab.
+
+## Enable or disable Product Analytics
+
+Product Analytics is under development and not ready for production use. It's
+deployed behind a feature flag that's **disabled by default**.
+[GitLab administrators with access to the GitLab Rails console](../administration/feature_flags.md)
+can enable it for your instance. Product Analytics can be enabled or disabled per-project.
+
+To enable it:
+
+```ruby
+# Instance-wide
+Feature.enable(:product_analytics)
+# or by project
+Feature.enable(:product_analytics, Project.find(<project id>))
+```
+
+To disable it:
+
+```ruby
+# Instance-wide
+Feature.disable(:product_analytics)
+# or by project
+Feature.disable(:product_analytics, Project.find(<project id>))
+```
+
+## Access Product Analytics
+
+After enabling the feature flag for Product Analytics, you can access the
+user interface:
+
+1. Sign in to GitLab as a user with Reporter or greater
+   [permissions](../user/permissions.md).
+1. Navigate to **Operations > Product Analytics**
+
+The user interface contains:
+
+- An Events page that shows the recent events and a total count.
+- A test page that sends a sample event.
+- A setup page containing the code to implement in your application.
+
+## Rate limits for Product Analytics
+
+While Product Analytics is under development, it's rate-limited to
+**100 events per minute** per project. This limit prevents the events table in the
+database from growing too quickly.
+
+## Data storage for Product Analytics
+
+Product Analytics stores events are stored in GitLab database.
+
+CAUTION: **Caution:**
+This data storage is experimental, and GitLab is likely to remove this data during
+future development.
+
+## Event collection
+
+Events are collected by [Rails collector](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/36443),
+allowing GitLab to ship the feature fast. Due to scalability issue, GitLab plans
+to switch to a separate application, such as
+[snowplow-go-collector](https://gitlab.com/gitlab-org/snowplow-go-collector), for event collection.
