Because Mochi’s core ingestion layer operates strictly through a standard client-side script tag, it remains structurally vulnerable to browser-level ad-blocking. If a security-conscious developer or privacy-focused buyer visits your site with aggressive content blockers engaged, the tracking script can be dropped entirely before it boots. When this occurs, the user's initial traffic footprint is completely lost; if they eventually convert, the backend Stripe webhook will still trigger correctly, but it will surface inside your dashboard as unclassified, orphaned revenue with zero structural channel history.
Additionally, the zero-configuration layout is deeply coupled with Stripe's ecosystem. If your application handles monetization through alternative merchant-of-record networks (such as Paddle, Lemon Squeezy, or specialized regional payment gates), the seamless automated mapping breaks down, shifting the data engineering burden back onto you to pipe custom events manually. Finally, tracking multi-touch attribution funnels—such as a user who discovers your product on a mobile device via social media but completes the final transaction days later on a desktop browser—can stress the boundaries of simplified cookie tracking frameworks.
