httpgrep

httpgrep is a high-performance asynchronous Python tool designed to scan HTTP(S) servers and search for specific strings or regex patterns within HTTP response bodies and headers. It supports a variety of input formats for target hosts, parallel scanning of multiple ports, and advanced features, including live match streaming, log file outputs in multiple formats, and the ability to resume interrupted scans, making it suitable for extensive network assessments. The tool is built for efficiency with an async core capable of handling thousands of concurrent connections while implementing intelligent timeout and port preflight mechanisms.
