## What it is
httprobe is a Go command-line tool that takes a list of domains on stdin and probes for working HTTP and HTTPS servers, reporting which respond. It supports custom protocol/port probes, configurable concurrency and timeouts, and a prefer-HTTPS mode.

## Use cases
- check which domains in a list have live web servers
- probe subdomains for http and https during recon
- find web services on non-standard ports like 8443
- filter alive hosts from a bug bounty target list
- quickly verify which endpoints serve https

## When to choose
- you need a fast, scriptable stdin/stdout tool for checking live web servers across many domains
- you want a lightweight single-purpose utility that fits into a recon or asset-discovery pipeline
- you need configurable concurrency and timeouts for large domain lists

## When to avoid
- you need full port scanning or service fingerprinting rather than just HTTP/HTTPS checks
- you want a GUI or a hosted service with dashboards and history
- you need deep crawling or content analysis of the discovered servers
