Stape and sGTM alternatives for first-party CAPI
Server-side GTM containers and Stape proxy Meta and Google through your subdomain. Purpose-built edge routers skip the GTM layer while keeping first-party delivery.

Problem: You set up Stape or a server-side GTM container to proxy Meta CAPI through gtm.yourdomain.com. It works, but debugging requires GTM preview mode and you still maintain tag containers.
What sGTM proxies solve
Server-side GTM moves tag execution off the browser onto your infrastructure. First-party subdomain requests avoid some block lists. Stape simplifies hosting sGTM on Cloud Run or Cloudflare.
You still think in GTM tags, triggers, and variables — not in canonical business events.
The SDK + edge alternative
An SDK sends events to your edge worker. The worker formats payloads per platform, retries failures, and writes delivery logs — no GTM container.
Configure event allowlists per platform in the dashboard.
trackstack.capture("Purchase", {
email: user.email,
value: 4999,
currency: "USD",
transactionId: "txn_abc",
eventId: "evt_purchase_abc",
});Choosing between approaches
Pick sGTM when marketing owns tag changes in GTM daily. Pick an edge conversion router when engineering owns revenue events and wants typed SDK capture.
Both can run first-party. The difference is operational model: tag containers vs canonical events in code.
Cost and complexity
sGTM hosting bills scale with request volume and container count. Edge routers optimized for conversion fan-out often reduce moving parts versus tag + client + server containers.

Google Tag Manager vs server-side conversion tracking
GTM excels at marketer-controlled tag deployment. Server-side CAPI excels at reliable delivery. Most teams need both — but not the same tool for both jobs.
