Neither Addingwell nor Aimerce is Littledata, so here's where Littledata wins:
Addingwell is a server-side GTM hosting solution — it improves tag performance and bypasses adblockers, but still relies on browser-initiated tags. It lacks direct Shopify server-side data access, meaning it misses events the browser doesn't see and can't natively enrich events with Shopify customer data. No identity resolution, no automatic checkout tracking, no Shopify Markets support.
Aimerce is closer in positioning but lacks native Shopify Markets support and automatic checkout step tracking. It also doesn't offer a 30-day free trial.
Littledata wins on:
For a Shopify Plus brand prioritizing complete, high-quality data with minimal setup, Littledata offers the most comprehensive out-of-the-box solution.

Addingwell focuses on paid media & analytics (GA4, Meta, Google Ads, TikTok, Pinterest, Snap, Microsoft Ads) — ideal for ad platform signal enrichment.
Aimerce has the narrowest coverage, targeting only Meta, Google Ads, and Klaviyo — with a specific focus on identity resolution and returning visitor recognition.
Littledata offers the broadest destination mix, uniquely adding Segment, Klaviyo, and Attentive alongside the standard ad/analytics stack — making it the strongest option if email/SMS marketing data pipelines (Klaviyo, Attentive) or a CDP layer (Segment) are priorities.
Key differentiator: Littledata bridges paid media and owned marketing channels; Addingwell is ad-focused; Aimerce is identity-focused with minimal destinations.
