## What it is
Logdy is a lightweight, single-binary realtime log viewer that pipes terminal output or log files into an embedded local web UI, acting like a combination of tail, grep, awk, sed, and jq with a browser interface. It can also be embedded as a Go library to stream application logs to a self-hosted UI.

## Use cases
- view tail -f logs in a web browser
- search and filter realtime application logs locally
- parse and transform log lines with custom TypeScript rules
- embed a log viewer UI into a Go application
- follow multiple log files at once
- inspect kubectl or shell command output in a UI

## When to avoid
- you need centralized log aggregation across many servers
- you require long-term log storage and retention
- you need a production-grade distributed logging pipeline
