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
open source escape hatches
- PostHog MIT
- Tracardi MIT
- Plausible Analytics AGPL-3.0
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.
