httpx is a fast and multi-purpose HTTP toolkit that allows running multiple probes using the retryablehttp library. It is designed to maintain result reliability with an increased number of threads.
- Simple and modular code base making it easy to contribute.
- Fast And fully configurable flags to probe multiple elements.
- Supports multiple HTTP based probings.
- Smart auto fallback from https to http as default.
- Supports hosts, URLs and CIDR as input.
- Handles edge cases doing retries, backoffs etc for handling WAFs.

httpx can be used as a library by creating an instance of the Option struct and populating it with the same options that would be specified via CLI. Once validated, the struct should be passed to a runner instance (to be closed at the end of the program) and the RunEnumeration method should be called. A minimal example of how to do it is in the examples folder
- As default,
httpxprobe with HTTPS scheme and fall-back to HTTP only if HTTPS is not reachable. - The
-no-fallbackflag can be used to probe and display both HTTP and HTTPS result. - Custom scheme for ports can be defined, for example
-ports http:443,http:80,https:8443 - Custom resolver supports multiple protocol (doh|tcp|udp) in form of
protocol:resolver:port(e.g.udp:127.0.0.1:53) - The following flags should be used for specific use cases instead of running them as default with other probes:
-ports-path-vhost-screenshot-csp-probe-tls-probe-favicon-http2-pipeline-tls-impersonate
