Littledata supports the most extensive list, including Google Analytics, TikTok, Pinterest, and Segment, catering to diverse analytics and marketing needs.

Littledata is superior for tracking customers from Shopify to Klaviyo due to its comprehensive approach to data privacy and customer identity.

This makes Littledata a more effective choice for CRM management.
