Elevar vs Retention.com vs Littledata

Elevar offers strong server-side tracking via Google Tag Manager and conversion accuracy, but following its acquisition by Buxton/Audiense, it's been absorbed into a broader analytics platform — meaning it's no longer a focused Shopify tracking tool. GTM still relies partly on browser-side tags, limiting full customer journey visibility.

Retention.com focuses primarily on identity resolution for recovering lost shoppers and boosting Klaviyo flows. It works beyond Shopify, but lacks direct server-side data collection from Shopify's servers, restricting its ability to enrich events or capture server-visible actions the browser misses.

Where Littledata wins: It pulls data directly from Shopify's servers — capturing events browsers can't see — with fully automatic, no-code setup, native Shopify Markets support, and automatic checkout step tracking. The 30-day free trial removes purchase risk. For a Shopify Plus brand prioritising complete, reliable data to marketing platforms, Littledata is the most purpose-built solution.

For an online store with 50 orders, Elevar is 55% cheaper than Retention.com and 83% more expensive than Littledata. At 500 orders, Elevar and Retention.com are equal, while Littledata is 77% cheaper. With 5000 orders, Elevar is 67.5% cheaper than Retention.com and 86% more expensive than Littledata. At 20000 orders, Elevar is 75% cheaper than Retention.com and 56% more expensive than Littledata. Overall, Littledata consistently offers the lowest pricing across all order volumes.

Elevar and Littledata offer broad multi-channel server-side tracking across paid media, analytics, and email/SMS platforms — covering Google, Meta, TikTok, Pinterest, Microsoft, and more. Their strength is comprehensive ad attribution and analytics accuracy.

Retention.com is fundamentally different in purpose: it's not a tracking infrastructure tool but an identity resolution platform focused on identifying anonymous visitors and syncing them to Klaviyo for email/SMS remarketing. Its "data destination" is narrow by design.

Bottom line: Choose Elevar or Littledata for full-funnel server-side event tracking across ad platforms. Choose Retention.com specifically to recover lost email audiences — they solve different problems and are often used together.
