The short version

  • Each has a real cost: OpenTelemetry genuinely complex to adopt: collectors, pipelines, samplers and exporters are a system to run in their own right; ProtonVPN free plan limited to one device at a time
  • They diverge on capability: OpenTelemetry covers Vendor-neutral SDKs, ProtonVPN covers No-logs policy.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

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

ProtonVPN

  • Free plan limited to one device at a time
  • Free plan restricted to 10 countries with random selection
  • Pricing amounts not clearly published; shown as variable

Answered from the vendors’ own pages

OpenTelemetry: Is OpenTelemetry free?

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

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.

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.
