+# OpenTelemetry Span Exporter - Standard output
+
+**Status**: [Stable](../../document-status.md)
+
+"Standard output" Span Exporter is a [Span
+Exporter](../sdk.md#span-exporter) which outputs the spans to
+stdout/console.
+
+[OpenTelemetry SDK](../../overview.md#sdk) authors MAY choose the best idiomatic
+name for their language. For example, ConsoleExporter, StdoutExporter,
+StreamExporter, LoggingExporter etc.
+
+If a language provides a mechanism to automatically configure a
+[Span processor](../sdk.md#span-processor) to pair with the associated
+exporter (e.g., using the [`OTEL_TRACES_EXPORTER` environment
+variable](../../configuration/sdk-environment-variables.md#exporter-selection)), by
+default the standard output exporter SHOULD be paired with a [simple
+processor](../sdk.md#simple-processor).
