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

Nexoya

You can build a cross-channel performance dashboard with automated spend alerts in a week using AI. However, building a trusted predictive optimization engine with two-way ad platform write integrations that automatically pushes thousands of dollars in daily budget edits requires extensive safety engineering, model tuning, and API maintenance.

you can rebuild

  • Cross-channel marketing performance reporting dashboard (Meta, Google, TikTok, LinkedIn).
  • Basic rules-based budget reallocation (e.g., shift budget if ROAS > X or CPA < Y).
  • Aggregated ROI, ROAS, and Spend tracking against defined target budgets.
  • Automated notification alerts when budget spend limits or target KPIs are breached.

what you lose

  • Pre-built, maintained two-way API write connectors for Google Ads, Meta, TikTok, LinkedIn, and Bing.
  • Out-of-the-box predictive algorithms calibrated for ad spend elasticity and conversion attribution lag.
  • Automated safety checks that prevent disastrous API overspending bugs during automated budget pushes.
  • A single managed interface for multi-channel campaign budget planning without maintaining infrastructure.

real moats

  • Trained predictive models fine-tuned on historical performance data across millions in cross-platform spend.
  • Two-way write access integrations with robust fail-safe controls and audited budget execution pipelines.
  • Enterprise trust and risk-mitigation framework required when allowing an automated tool to execute monetary budget changes.
