## What it is
httpx is a fast, multi-purpose HTTP toolkit written in Go that runs multiple probes (status codes, titles, TLS certificates, tech detection, etc.) against lists of hosts, URLs, or CIDRs using the retryablehttp library. It is designed for reliability at high thread counts and fits into reconnaissance and vulnerability-detection pipelines.

## Use cases
- probe a list of subdomains for live web servers
- check http status codes and page titles for many urls
- enumerate ssl certificates and web server headers across cidr ranges
- filter live hosts during bug bounty reconnaissance
- feed discovered assets into a vulnerability scanning pipeline
- detect cdns and wafs behind web endpoints

## When to choose
- you need fast, threaded HTTP probing of large host lists
- you want a pipeline-friendly CLI that accepts hosts, URLs, and CIDRs
- you need reliable results with retries and WAF handling built in

## When to avoid
- you need a Python HTTP client library - this is the unrelated Go tool of the same name
- you need full vulnerability exploitation rather than probing and metadata collection
- you need a GUI-based scanner
