httpx

httpx is a versatile and high-performance HTTP toolkit designed for probing web services effectively. Its primary use case focuses on conducting a variety of HTTP-based checks such as status codes, content length, and various headers, equipped with features like smart fallback from HTTPS to HTTP, multi-threading, and error handling for WAFs. With a modular code base and customizable flags, httpx allows users to efficiently gather information from URLs, IPs, or CIDR networks while automatically managing retries and backoff strategies.
