Stape focuses on server-side tracking via Google Tag Manager, improving data quality across multiple platforms. However, GTM still relies on browser-side tags, limiting its ability to capture server-side Shopify events or enrich data the browser doesn't see.
Retention.com specializes in identity resolution to recover lost shoppers and boost Klaviyo flows, but is narrowly focused on audience building rather than comprehensive tracking.
Neither pulls data directly from Shopify's servers, which is where Littledata wins:
For an ecommerce manager prioritizing data completeness and marketing ROI, Littledata offers the most purpose-built, Shopify-native solution.

Stape and Littledata offer broad multi-channel tracking across paid media, analytics, and email platforms — ideal if you need unified server-side data across your entire marketing stack.
Retention.com is narrowly focused on Klaviyo, positioning it primarily as an email/SMS identity resolution and list-growth tool rather than a comprehensive tracking solution.
Littledata adds Segment as a destination (unlike Stape), making it stronger for teams using a CDP layer.
Bottom line: If you need full-funnel server-side tracking across paid + owned channels, Stape or Littledata are better fits. Retention.com serves a different purpose — maximizing identified email audiences — and shouldn't be evaluated as a direct tracking alternative.
