Bily ‑ CAPI Ai Tracking and Retention X both aim to improve ad performance by leveraging conversion APIs, but they cater to different segments of Shopify merchants. Bily is positioned as a simple, easy-to-use solution primarily focused on accurately tracking conversions and bypassing limitations imposed by iOS14 and ad blockers. Its strength lies in its straightforward implementation of server-side tracking for Facebook, Google, and TikTok. Bily's core value proposition is delivering accurate data to ad platforms. It appears to be targeting smaller merchants or those needing a more focused conversion tracking solution. Retention X, on the other hand, is a comprehensive e-commerce growth OS.

Retention X's strength is its unified platform that encompasses a wider range of functionalities for customer-obsessed teams looking to optimize various aspects of their business, from acquisition to retention. The key difference lies in the scope. Bily is primarily a tracking app solving a specific tracking problem whereas Retention X is a comprehensive solution trying to address customer intelligence, conversion tracking, attribution and automation in one platform.
