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; Redpanda the community edition is source-available rather than OSI open source, which matters for some procurement
  • They diverge on capability: OpenTelemetry covers Vendor-neutral SDKs, Redpanda covers Kafka API compatible.
  • Prices and features above were last checked on 29 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

OpenTelemetry

  • Instrumenting once and keeping the option to change observability vendor laternot Redpanda
  • Standardising telemetry across services written in different languagesnot Redpanda
  • Routing and filtering telemetry centrally to control observability spendnot Redpanda

Redpanda

  • Kafka workloads where the operational cost of running Kafka is the blockernot OpenTelemetry
  • Latency-sensitive streaming where tail latency mattersnot OpenTelemetry
  • Smaller teams wanting streaming without a dedicated platform groupnot OpenTelemetry

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

Redpanda

  • The community edition is source-available rather than OSI open source, which matters for some procurement
  • Kafka API compatibility is high but not total, and deep ecosystem tools can hit gaps
  • Smaller community than Kafka, so fewer people have solved your problem before
  • Some operational and tiered-storage features are enterprise-only

Does OpenTelemetry or Redpanda run on more platforms?
OpenTelemetry runs on Linux, macOS, Windows, Kubernetes, Docker. Redpanda runs on Linux, Docker, Kubernetes, Self-hosted.
Can I use OpenTelemetry for free?
Both have a free tier, so you can try either at no cost before committing.
What is OpenTelemetry best used for?
OpenTelemetry is most often used for instrumenting once and keeping the option to change observability vendor later, standardising telemetry across services written in different languages, routing and filtering telemetry centrally to control observability spend. Of those, instrumenting once and keeping the option to change observability vendor later and standardising telemetry across services written in different languages are not what Redpanda is typically brought in for.
What can OpenTelemetry do that Redpanda cannot?
OpenTelemetry covers Vendor-neutral SDKs, Collector, Three signals, Auto-instrumentation. Redpanda covers Kafka API compatible, No JVM or ZooKeeper, Thread-per-core, Built-in HTTP proxy and schema registry.

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.

Redpanda: Is Redpanda free?

A community edition is free and source-available. Enterprise features and Redpanda Cloud are paid, and the licence is not OSI open 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.

Redpanda: Can I use my Kafka clients?

Yes. Redpanda implements the Kafka API, so existing clients and most tooling connect without changes.

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.

Redpanda: Why remove ZooKeeper and the JVM?

Both are significant sources of Kafka’s operational burden — tuning, coordination and failure modes. Removing them is the core of Redpanda’s pitch.
