our call

Start with Cometly — highest vibe code, weakest moat.

Cometly

Building a basic UTM recorder with a dashboard takes a weekend. Replicating multi-touch attribution, server-side CAPI event deduplication, and maintaining ad platform API connections against breaking changes across Meta, Google, and TikTok is a full-time engineering effort.

you can rebuild

  • UTM parameter capturing and first-party cookie tracking scripts
  • First-touch and last-touch attribution SQL query logic
  • Analytics dashboard displaying CAC, ROAS, and ROI per ad campaign
  • Shopify webhook receiver for sales conversion ingestion
  • Basic server-side event payload generation

what you lose

  • Turnkey client/server event deduplication across Meta, TikTok, and Google
  • Automated token refresh and API schema maintenance across ad platforms
  • Pre-packaged identity stitching across multi-device user journeys
  • Ad spend ingestion pipelines that handle API rate limits and currency conversions
  • No-code Shopify theme app integration

real moats

  • Maintained native integrations with rapidly evolving ad platform APIs
  • First-party identity graph infrastructure optimized for browser privacy limits
  • Turnkey server-side tracking bypassing Safari ITP and ad blockers without custom DNS configuration

Intelligems

A basic 50/50 product price or shipping fee split-testing script can be built in a weekend using Cloudflare Workers and Shopify Functions. Replicating full revenue-per-visitor attribution, flicker-free edge price rewrites, and statistical confidence models requires serious backend engineering.

you can rebuild

  • 50/50 product price split testing via client-side cookie assignment
  • Dynamic shipping threshold A/B testing at cart and checkout
  • Basic visitor and conversion tracking by price variant
  • Geographic price variant assignment using edge IP lookup
  • Session persistence to ensure returning visitors see identical test prices

what you lose

  • Flicker-free edge rendering engineered specifically for Shopify storefronts
  • Automated Bayesian statistical significance and Revenue Per Visitor (RPV) lift calculations
  • No-code Shopify Functions UI for configuring dynamic shipping rules and rates
  • Automated integration with Google Shopping feed prices to prevent ad disallowance
  • Cross-experiment traffic isolation logic to prevent multi-test skew

real moats

  • Deep native integration with Shopify Checkout Extensibility and Shopify Functions
  • Zero-flicker edge routing infrastructure preventing Cumulative Layout Shift (CLS)
  • Domain-specific statistical engine optimized for high-variance ecommerce order values
