## What it is
otel-tui is a terminal-based OpenTelemetry viewer that receives traces, metrics, and logs via OTLP (gRPC/HTTP) and displays them in a TUI. It also supports Zipkin, Prometheus, and Datadog signal formats and is inspired by otel-desktop-viewer.

## Use cases
- view opentelemetry traces in the terminal
- inspect spans and service topology locally
- debug telemetry from an instrumented app without a backend
- view logs and metrics from OTLP exporters
- receive zipkin or datadog traces in a local viewer
- scrape prometheus targets and view metrics in a TUI

## When to choose
- you want a lightweight local OpenTelemetry collector with a terminal UI
- you're developing instrumented services and need quick trace/log/metric inspection
- you prefer terminal tools over web dashboards like Jaeger UI

## When to avoid
- you need persistent storage or long-term telemetry retention
- you need a shared/team dashboard or alerting
- you need full OpenTelemetry Collector processing pipelines
