OpenTelemetry (OTel) was supposed to standardize observability and kill vendor lock-in. In 2026, OTel is the standard... but vendors have adapted.

OpenTelemetry Successes:

  • CNCF's 2nd most active project behind K8s
  • Native support in all major languages (auto-instrumentation improving rapidly)
  • Collector architecture enables flexible pipelines
  • eBPF integration for zero-code instrumentation

The 2026 Reality:

  • Most orgs use OTel for data COLLECTION
  • But still send to commercial backends (Datadog, Honeycomb, Grafana Cloud)
  • Vendors now compete on analysis, AI-powered insights, and UI
  • Open source backends (Jaeger, Prometheus, Tempo, Loki) for cost-sensitive teams

Vendor Landscape 2026:

  • Datadog: Most complete, most expensive, best for unified observability
  • Honeycomb: High-cardinality champion, best for debugging complex systems
  • Grafana Cloud: LGTM stack (Loki, Grafana, Tempo, Mimir), cost-effective
  • New Relic: Reinvented with better pricing, strong APM
  • Chronosphere: For truly massive scale (DoorDash, Snap, Uber)

Debate Questions:

  • Is OTel actually reducing vendor lock-in or just shifting the lock-in point?
  • What's your observability stack cost vs value?
  • Are you using eBPF? What's the experience like?
  • Logs vs metrics vs traces - what's your priority?
