## What it is
A CLI tool for receiving and exploring OpenTelemetry traces, metrics, and logs locally, built in Go on top of the OpenTelemetry Collector with a DuckDB backend and a Svelte web UI. It exposes OTLP gRPC and HTTP receivers and serves a local web UI for inspecting telemetry data.

## Use cases
- view opentelemetry traces locally while developing
- inspect otel metrics and logs on my machine
- local otel collector with a web ui
- debug distributed tracing during local development
- receive otlp data on localhost without a backend
- explore telemetry signals before shipping to a vendor

## When to choose
- you need a zero-setup local viewer for OpenTelemetry traces, metrics, and logs
- you want to inspect OTLP data during development without running a full observability backend
- you prefer a lightweight CLI tool with a built-in web UI

## When to avoid
- you need production-grade telemetry storage, alerting, or team-wide dashboards
- you require long-term retention or querying of telemetry at scale
- your Linux distribution ships an older glibc than 2.39
