The short version

Each has a real cost: Cloudflare free tier limited to basic features (no advanced analytics or premium features); OpenTelemetry genuinely complex to adopt: collectors, pipelines, samplers and exporters are a system to run in their own right
They diverge on capability: Cloudflare covers Global CDN, OpenTelemetry covers Vendor-neutral SDKs.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Cloudflare

Free tier limited to basic features (no advanced analytics or premium features)
Pro tier ($20-25/month) caps at professional websites (higher tiers needed for enterprise scale)
Caches only anonymous API GET responses (authenticated requests and non-GET methods not cached)
Geographic coverage limited to announced 330+ cities (may not cover all regions globally)

OpenTelemetry

Genuinely complex to adopt: collectors, pipelines, samplers and exporters are a system to run in their own right
Language SDKs mature at different rates, so a polyglot estate gets uneven support
It produces and moves telemetry but does not store or visualise it, so a backend is still required and still billed

Answered from the vendors’ own pages

Cloudflare: Does Cloudflare have a free tier?

Yes, Cloudflare includes a free tier with generous allowances: 100k daily requests for Workers, 10 GB monthly storage for R2, and 1 GB for Workers KV.

Source

OpenTelemetry: Is OpenTelemetry free?

Yes, open source under the CNCF. What you pay for is the backend you export to.

Cloudflare: How much does Cloudflare cost beyond the free tier?

Cloudflare uses pay-as-you-go pricing beyond free allocations, charging per million requests, per GB-month of storage, or per vCPU-second depending on the service.

Source

OpenTelemetry: Does OpenTelemetry replace Datadog or Grafana?

No. It replaces their proprietary agents and instrumentation libraries. You still need a backend to store and query the data.

Cloudflare: Does Cloudflare charge egress fees?

No, Cloudflare explicitly states no egress fees and no hidden costs; you only pay for the usage metrics specific to each service.

Source

OpenTelemetry: Why adopt a vendor-neutral standard?

Because instrumentation is the expensive part. Once code emits OTel, changing observability vendor is a collector config change instead of re-instrumenting every service.

Cloudflare: What's the Enterprise pricing model for Cloudflare?

Cloudflare Enterprise offers custom pricing and volume discounts available through direct sales for organizations with specialized needs and large-scale usage.
