Convultra vs Cloudflare Zaraz
Tag Delivery vs Conversion Intelligence
Cloudflare Zaraz appears in "server-side tracking" searches, leading marketers to wonder if it's an alternative to conversion tracking platforms. The short answer: no. They solve fundamentally different problems — and can actually be complementary.
Choose Convultra if:
Best for most teams
- You need accurate conversion data that actually improves ad performance
- You want automatic deduplication across browser and server events
- You need click ID persistence (gclid, fbclid, msclkid) across sessions
- You want Event Match Quality monitoring and optimisation
- You need bot detection to filter fake conversions
- You're an agency needing multi-tenant tracking
- You want to see which conversions were delivered vs failed
Choose Cloudflare Zaraz if:
May be better for some use cases
- Your primary problem is page speed from third-party scripts
- You just need to relay events without any intelligence layer
- You're already on Cloudflare and want basic server-side delivery
- You have developers to handle deduplication, click ID persistence, and debugging manually

Detailed breakdown of each key differentiator.
Deduplication
The Claim
Convultra automatically deduplicates events. Zaraz generates random event IDs that don't match client-side ones.
The Evidence
This is a known pain point in the Cloudflare community. Zaraz generates random event IDs for server-side events. If you run both browser pixels and Zaraz (recommended for maximum coverage), you have to manually wire up deduplication yourself. Without proper dedup, you count conversions twice.
Why It Matters
Ad platforms see inflated numbers. Your optimisation is based on bad data. Campaign performance suffers because you're training algorithms on duplicate events.
Verdict
Convultra wins with five-layer automatic deduplication.
Click ID Persistence
The Claim
Convultra stores click history for 90 days. Zaraz doesn't capture or store click identifiers across sessions.
The Evidence
A user clicks your Meta ad on Monday, browses, leaves without buying. They return directly on Thursday and purchase. Without click ID persistence, that conversion can't be attributed to the original ad click. If an event is blocked before reaching Zaraz's edge worker, the click ID is lost entirely.
Why It Matters
Meta never learns their ad drove the sale. Your attribution data is incomplete. You're optimizing campaigns blind.
Verdict
Convultra wins with 90-day click ID storage in localStorage.
Analytics & Debugging
The Claim
Convultra provides full conversion analytics and delivery logs. Zaraz has no dashboard and breaks standard debugging tools.
The Evidence
Zaraz has no dashboard showing conversion counts, revenue, or forwarding status. Worse: Meta's Test Events and GA4's DebugView don't work through Zaraz — making debugging significantly harder. You're entirely dependent on receiving platforms to tell you what happened.
Why It Matters
When conversions don't match, you need to troubleshoot. Without delivery logs or working debug tools, you're guessing. Convultra shows you exactly which conversions succeeded, failed, or are pending.
Verdict
Convultra wins with full analytics and debugging visibility.
Multi-Tenant / Agency Support
The Claim
Convultra has purpose-built agency features. Zaraz doesn't work well for agencies.
The Evidence
Cloudflare community feedback confirms Zaraz doesn't work well when each client needs separate pixel IDs and API tokens. Convultra was built for agencies from day one: dedicated agency dashboard, client management, one-click login as client, automated reports.
Why It Matters
Agencies managing multiple clients need multi-tenant support. With Zaraz, you'd need separate Cloudflare accounts or complex workarounds for each client.
Verdict
Convultra wins for agencies with multi-tenant architecture.
