Shopify has a built in free connector for Meta Ads as part of the Facebook Sales Channel. This was built in 2021 and is maintained by Shopify.

Facebook & Instagram App is Shopify's native Meta connector (free, no-code), but it's limited to Meta platforms only and lacks identity resolution — meaning you're working with whatever audience data Meta already has.
Retention.com adds identity resolution to boost audiences and works across platforms beyond Shopify, making it more versatile for recovering lost shoppers and feeding Klaviyo flows.
Where Littledata wins over both:
Neither competitor pulls data directly from Shopify's servers. This is a critical gap — browser-based tracking misses server-side events, checkout steps, and customer enrichment that only server-side capture provides. Specifically:
Littledata combines identity resolution + server-side tracking + no-code setup + Shopify Markets support — giving you the most complete, accurate customer journey data of the three, across any marketing platform.

Meta Ads (Facebook/Instagram app): Sends event data directly to Meta's Conversions API for ad attribution and optimization — focused solely on fueling Meta's ad platform.
Retention.com → Klaviyo: Identifies anonymous site visitors and pushes them into Klaviyo as profiles/events, primarily enabling email/SMS retargeting flows for otherwise lost traffic.
Littledata: Acts as a server-side data pipeline across multiple destinations simultaneously — enriching and forwarding accurate Shopify event data to ad platforms (Meta, Google, TikTok, Pinterest, Microsoft), analytics (GA4, Segment), and owned marketing tools (Klaviyo, Attentive). It's a centralized tracking layer focused on data accuracy and deduplication across your entire stack.
Bottom line: Littledata is infrastructure; the others are point solutions for specific channels.
