Addingwell is a fully-managed GTM server-side hosting + tooling (monitoring, adblocker bypass, Safari resilience) to improve data quality, performance and governance.

Shopify has a built in free connector for Meta Ads as part of the Facebook Sales Channel. This was built in 2021 and is maintained by Shopify.

Neither Addingwell nor the Facebook & Instagram app is Littledata, so here's where Littledata wins:
vs. Addingwell: Addingwell is server-side GTM hosting, but Google Tag Manager still relies on browser-based tags as its data source. Without a direct Shopify server-side connection, it can't fully enrich events with customer data or capture events the browser misses. Littledata pulls data directly from Shopify's servers, giving a more complete customer journey view.
vs. Facebook & Instagram app: Shopify's native Meta connector is browser-dependent and basic — built in 2021 with no identity resolution or cross-platform flexibility. Littledata adds identity resolution to boost Meta audiences, automatic checkout step tracking, and native Shopify Markets support.
Littledata's key advantages over both:
Addingwell vs Facebook & Instagram app's customer reviews
| Addingwell | Facebook & Instagram app | Littledata | |
|---|---|---|---|
| Example product review | Setup took just a few seconds, and it works right away. All my pixels from GTM are now server-side and perfectly connected. So much money saved on ads. | "Tracking is inaccurate, ad spend wasted, and support is unhelpful...data doesn’t match up, making it impossible to optimize campaigns." | "We were having difficulties with accurate and consistent revenue attribution...With Littledata implemented, we now get consistent and accurate revenue attribution." |
| Example support review | The support was very fast to answer our questions and super helpful. Just be careful to check that the events don't trigger twice. | "Cannot get anyone to follow through and help me... I get bounced around from tech support person to another." | "Customer support is absolutely amazing... you can never go wrong when an app does what it says and tacks on great service!" |

Addingwell focuses on paid media channels (GA4 + 7 ad platforms), making it strong for multi-channel ad attribution via server-side.
Facebook & Instagram App is single-destination only (Meta), limiting its utility as a comprehensive tracking solution.
Littledata mirrors Addingwell's channel coverage but adds CRM/retention integrations (Klaviyo, Attentive, Segment), making it better suited if email/SMS marketing data pipelines matter to you.
Key takeaway: If your priority is paid media tracking, Addingwell and Littledata are comparable. If you also need server-side data flowing into retention tools like Klaviyo or Attentive, Littledata has the edge. The Facebook app is too narrow for a comprehensive solution.
