Compare with other solutions Solution selector

Best for

  • sites already on Cloudflare (CDN, Workers, R2)
  • fast server-side without Docker container maintenance
  • reducing client-side tags and improving performance

Strengths

  • Runs on edge - low latency, fewer browser scripts
  • Integrations with marketing and analytics tools
  • Part of Cloudflare ecosystem - easy start if domain is on CF
  • Usage model with free tier to start

Weaknesses

  • Not a GTM Server-Side container - different setup than sGTM
  • Less flexibility than full GTM SS for complex tags
  • Migration from client GTM requires redesign, not lift-and-shift

When to choose

  • You already use Cloudflare and want server-side on edge
  • Site performance and fewer browser tags are priorities
  • You don't need full GTM SS template ecosystem

When to avoid

  • You have extensive client GTM and want 1:1 sGTM container
  • Stack requires GTM SS-only community templates
  • Domain is not on Cloudflare and you won't migrate
