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
