Core Concept

Events represent actions performed by your website visitor or customer.

Events are the central measurement of who, how, and when your website or application is being used. Events may be collected using Firstparty.js, the Firstparty HTTP API, or a Warehouse Source, and can be sent to an unlimited number of Warehouses of your choice.

Accurate measurement

Increase data quantity & quality

Firstparty serves cookies and its tracking library from your website's domain. This means browsers and ad blockers won't prevent you from collecting the data you need to run your business.

Reduce Customer Privacy Infringement

Firstparty keeps cookies on your domain, so your customers are never tracked once they leave your site.

Safer (first-party) cookies

By restricting cookies to your domain and never sharing them with a third-party, your website visitors can't be tracked across the internet with Firstparty data.

We Never Share Data

Firstparty will never share your data with anyone but who you tell us to. Want to run completely isolated from third-party marketing systems? No problem.
