Both Elevar and Blotout offer server-side tracking and identity resolution, but each has limitations:

Elevar was built around Google Tag Manager, meaning it still relies partly on browser-side tags — limiting full event capture. Its acquisition by Buxton/Audiense has shifted focus toward broader analytics, making it less purely a Shopify tracking tool.

Blotout is platform-agnostic and founder-led, but its primary focus is identity resolution for anonymous visitors rather than comprehensive conversion tracking.

Littledata wins because:

• It sends data directly from Shopify's servers, capturing events the browser never sees — including checkout steps and post-purchase flows — giving a more complete customer journey view than GTM-dependent solutions
• No-code, fully automatic setup reduces implementation risk
• Native Shopify Markets support is critical for international Shopify Plus brands
• A 30-day free trial lets you validate tracking accuracy before committing
• Purpose-built for Shopify, not a broader analytics pivot

For 50 orders, Elevar is 185% more expensive than Blotout and 476% more than Littledata. At 500 orders, Elevar and Blotout are equal, while Littledata is 77% cheaper than both. For 5000 orders, Elevar is 67% cheaper than Blotout but 86% more expensive than Littledata. At 20000 orders, Elevar is 75% cheaper than Blotout and 56% more expensive than Littledata. Overall, Elevar is consistently the most expensive, while Littledata offers the lowest pricing across all order volumes.

Elevar and Littledata offer the broadest destination coverage, both including TikTok, Pinterest, and Microsoft Ads. Littledata uniquely adds Segment, making it ideal if you use a CDP or route data to additional downstream tools.

Blotout has the narrowest native destination list, lacking TikTok, Pinterest, and Microsoft Ads — its differentiation lies more in its privacy-first, first-party data infrastructure than destination breadth.

If channel coverage is your priority, Elevar and Littledata are comparable, with Littledata's Segment integration giving it an edge for more complex data stacks.

Elevar's purchase tracking for Google Analytics ensures GDPR/CCPA compliance by allowing end-users to opt out without adding new emails to marketing lists. In contrast, Blotout offers server-side tracking for 100% accuracy but lacks specific compliance features. Littledata also provides server-side tracking with enhanced features like post-purchase upsells, recurring orders, order filtering by sales channel, refunds, user-provided data for better attribution, and custom mapping. While Elevar focuses on compliance and opt-out options, Blotout and Littledata emphasize accuracy and additional functionalities, with Littledata offering the most comprehensive tracking capabilities.

Littledata outperforms both alternatives for Shopify-to-Klaviyo tracking:

vs. Elevar: While Elevar matches on consent compliance and email suppression, Littledata's server-side Shopify connection eliminates the need for manual checkout tagging and captures far more identified customers on Product Viewed events. Elevar's client-side approach also creates noisy Klaviyo profiles without emails.

vs. Blotout: Blotout only matches on email suppression. Without server-side Shopify data, you'll face all three disadvantages: profile noise, manual checkout setup, and poor Product Viewed identification rates.

Littledata's unique advantages — boosting identity via cross-channel cookies and backstitching profiles onto historical events — mean richer, more complete customer journeys in Klaviyo that neither competitor can replicate.
