otel-tui is a terminal-based observability viewer that lets you inspect telemetry data directly from a text user interface.
It can receive OpenTelemetry data over OTLP, ingest Zipkin traces, scrape Prometheus metrics, and accept Datadog traces, metrics, and logs, making it a handy local tool for exploring application behaviour without needing a full browser-based observability stack.
This is free and open source software.
