## What it is
Updo is a command-line uptime and performance monitoring tool for websites, providing real-time metrics on status, response times, and SSL certificate expiry. It supports multi-target and multi-region (AWS Lambda) monitoring, alert notifications via desktop and webhooks, and Prometheus/Grafana metric export.

## Use cases
- monitor website uptime from the command line
- get alerts when a site goes down
- track ssl certificate expiry dates
- monitor multiple urls concurrently
- export uptime metrics to prometheus and grafana
- run health checks from multiple global regions
- watch response times in a terminal dashboard

## When to choose
- you want lightweight, scriptable uptime monitoring without running a full server
- you prefer a terminal-based tool with TUI, text, or JSON output
- you need webhook alerts to Slack, Discord, or custom endpoints
- you want quick SSL expiry and response-time checks for a handful of sites

## When to avoid
- you need a hosted dashboard with team access and history UI
- you require distributed synthetic monitoring at large scale with many probes
- you need status pages or incident management workflows
