Retention.com is a better choice if your goal is de-anonymising website traffic into contactable emails to grow owned email and SMS remarketing. Littledata is the better fit for teams who want turnkey, fully managed server-side tracking without building or maintaining tag infrastructure.

Blotout is a better choice if you want a broader multi-vertical server-side data layer or CDP with compliance needs beyond Shopify. Littledata is the better fit for teams who want turnkey, fully managed server-side tracking without building or maintaining tag infrastructure.

Littledata sends purchase and behavioural data server-to-server, directly from Shopify's servers, so it does not depend on browser tags or a Google Tag Manager container you have to maintain. Tracking keeps working when Shopify changes the checkout, and events can be enriched with customer and order data the browser never sees. Tools built on server-side Google Tag Manager still rely on browser tags to collect events, and someone has to build and maintain the container.

No. Littledata is turnkey: install the Shopify app and server-side tracking is live, with no code and no Google Tag Manager required. Self-managed server-side setups typically need 10 to 40 hours of specialist configuration up front, plus a few hours a month of ongoing maintenance, which is why a low sticker price often hides a much higher true cost.

Littledata's Event Editor lets you customise and enrich the events sent to each destination without code, so you control exactly what data reaches Google Analytics, Meta, Klaviyo and your other marketing tools.

Littledata's Profit signal sends true profit, not just revenue, to your ad platforms, so Meta and Google can optimise campaigns towards the orders that actually make you money.
