## What it is
A Python rewrite of the Slowloris low-bandwidth HTTP Denial of Service attack tool. It holds many connections open to threaded web servers by periodically sending headers, exhausting the server's thread pool.

## Use cases
- test my web server's resilience to slowloris DoS attacks
- run a low bandwidth denial of service test against a threaded HTTP server
- simulate connection exhaustion attacks during a pentest
- check whether my server's thread pool survives slow header attacks
- perform authorized load testing with SOCKS5 proxy support

## When to choose
- you need a simple, pip-installable CLI for slowloris-style DoS testing
- you want low-bandwidth attack simulation without flooding traffic
- you need SOCKS5 proxy or HTTPS options during security assessments

## When to avoid
- you need general-purpose load or performance testing with metrics
- you want protection or mitigation tooling rather than attack simulation
- you lack explicit authorization to test the target server

## Facets
- artifact type: cli-tool
- maturity: stable
- function: penetration-testing, http-client, cli
- domain: security, penetration-testing, networking
