One of the most valuable capabilities of Stape.io is setting first-party cookies on your domain via the server container — giving you cookie lifetimes of up to 7 years in Safari (vs. 7 days with client-side ITP-restricted cookies). Adslytics configures Stape to set and manage first-party cookies for GA4 client ID and ad click IDs.
