Because the output is plain OpenTelemetry, it works with Datadog, Honeycomb, Grafana and others, and its semantic conventions became part of OpenTelemetry. Add one instrumentation if you already run OTel, or use the Traceloop SDK to start quickly. A JS/TS version exists as OpenLLMetry-JS. ★~7.5k.","theCatch":"Traces can include prompts and completions, which may hold personal data, so configure content capture deliberately. The Traceloop SDK defaults point toward Traceloop's hosted platform; set your own exporter. It is instrumentation, not a UI, so you still need a backend.","verdict":"The vendor-neutral way to get LLM calls into your existing tracing.","addedAt":"2026-10-18","featured":false,"domain":"Observability","subSpecialty":"Observability","subcategory":"Observability","tags":["self-host","permissive","vector","observability","active"],"capabilities":[],"surfaces":["Self-host"],"ecosystem":["Multi-platform"],"licenseModel":"Apache-2.0","githubStars":7501,"starsPerWeek":46,"access":"free","archived":false,"repo":{"createdAt":"2023-09-02","pushedAt":"2026-10-13","license":"Apache-2.0","archived":false,"checkedAt":"2026-10-19"}},"related":[{"slug":"sentry","name":"Sentry","tagline":"Error tracking that actually helps"},{"slug":"grafana","name":"Grafana","tagline":"Dashboards for everything observable"},{"slug":"prometheus","name":"Prometheus","tagline":"Time-series metrics for cloud-native"},{"slug":"opentelemetry","name":"OpenTelemetry","tagline":"Vendor-neutral observability framework"},{"slug":"datadog","name":"Datadog","tagline":"Unified observability platform"}],"links":{"self":"/api/gems/openllmetry","html":"/gems/openllmetry","markdown":"/gems/openllmetry.md","category":"/api/gems?category=observability","categoryPage":"/stacks/observability"}}
