Tixels

Tixels is a Shopify app that moves conversion tracking server-side because ad blockers, Safari's cookie limits and browser-side pixels increasingly hide sales from the ad platforms merchants pay. A tracker on the store records browsing and checkout events and a Cloudflare Worker fans each one out to nine ad and marketing platforms, Meta, Google, TikTok, Snapchat, Pinterest, GA4, Klaviyo, Reddit and X, in parallel. Personal data only flows with explicit consent, is hashed at the edge by each platform's own rules, and is stripped before anything is stored.

The data lands in the merchant's own self-hosted ClickHouse analytics store, and a dashboard shows pixel health, a live event feed, and which ads actually drove sales across several attribution models. Deduplication happens in three layers, exact dedupe at the edge, a de-duplicating table in ClickHouse, and a shared event ID passed to each platform, so a sale is never double-counted across all nine destinations. The tracker is kept to roughly 3KB with a build-time size check that fails the build if it grows.

Tixels' development is complete: the marketing site is live and the pipeline is built and security-hardened, with Shopify App Store submission the remaining step.
