# OpenTelemetry: Pricing, Features & Alternatives

OpenTelemetry is not a dashboard. It is the CNCF standard, SDKs and Collector that decide what a trace looks like and where it gets sent. Its GenAI semantic conventions now live in their own repository and cover spans, metrics and events for model clients, MCP and provider-specific calls (OpenAI, Anthropic, Bedrock, Azure AI). Instrument once with OTel and the traces can go to Langfuse, LangSmith, Braintrust or a Grafana stack you run yourself. That is why it belongs on this list: it is how you avoid getting locked into any of them.
