{"slug":"best-self-hosted-opentelemetry-backends-for-kubernetes","title":"Best Self-Hosted OpenTelemetry Backends for Kubernetes","question":"What are the best self-hosted OpenTelemetry backends for Kubernetes in 2026?","verdict":"As of 2026-08-10, ChatGPT, Claude, Gemini and Grok collectively rank Grafana LGTM #1 for self-hosted opentelemetry backends for kubernetes on ModelsAgree by aggregate score. The models' case: Purpose-built for traces, object-storage-backed (S3/GCS) so retention is cheap at scale, integrates natively with Loki (logs) and Mimir (metrics) under one Grafana pane. The models' main caveat: It's traces-only — you must assemble and operate Loki + Mimir + Grafana + collectors yourself to get full OTel coverage, which is real operational. The strongest alternative is SigNoz — The best overall balance of OpenTelemetry-native ingestion, correlated logs/metrics/traces, strong APM and exception workflows, alerting, ClickHouse. Not unanimous: ChatGPT picks SigNoz; Gemini picks SigNoz; Grok picks SigNoz.
