awesome-hacker-search-engines is a curated list of search engines and tools for security professionals conducting penetration tests, vulnerability assessments, red team operations, and bug bounty work.
The project addresses the problem of discovering specialized search engines and query tools that expose security-relevant information during offensive and defensive security work. Rather than building its own search functionality, it aggregates existing engines and platforms—organized by category—that security practitioners can use to find vulnerabilities, exposed credentials, DNS records, exploits, CVE data, and other threat intelligence. The list covers OSINT tools, threat intelligence platforms, and specialized search capabilities designed for security research.
The tool suits security professionals who need a reference guide to available search resources rather than a single integrated platform. It works well for penetration testers building reconnaissance workflows, bug bounty hunters searching for attack surface information, and red team operators gathering intelligence. The project is structured as a browsable list with a companion website, making it useful as a bookmark or reference during security engagements when you need to know which search engine to use for a particular type of query.
The project maintains an organized, categorized collection that grows through community contributions. The repository accepts pull requests to add new search engines and tools, indicating active curation and expansion of the resource list. The accompanying website provides an accessible interface to the curated data, suggesting ongoing maintenance of both the repository and its public-facing presentation.
