httprobe

httprobe is a command-line tool that checks a list of domains to determine which ones have active HTTP or HTTPS services running. It reads domains from standard input and attempts connections on common ports such as 80 and 443, returning only those that respond successfully. The tool is designed for speed and efficiency, allowing users to process large lists of domains with configurable concurrency levels. It supports additional probes on custom ports and protocols, enabling more flexible scanning scenarios. httprobe also allows users to adjust timeouts and prioritize HTTPS results, making it adaptable to different reconnaissance needs. Its output can be easily piped into other tools for further analysis, such as vulnerability scanning or content discovery.
