OneForAll is a powerful subdomain collection tool
...The tool is particularly notable for incorporating many Chinese data sources that are often missed by Western-focused recon tools, increasing discovery coverage. It supports brute-force subdomain discovery, recursive scanning, and takeover detection to help identify potential attack surfaces. OneForAll also performs validation and enrichment of discovered domains, producing structured outputs for further analysis. Overall, it is a powerful asset discovery platform designed to maximize subdomain visibility during security assessments.
