This repository is a curated list (awesome list) of open-source intelligence (OSINT) tools and resources. It is not a software application or a data research pipeline; it is a static markdown document that categorizes and links to hundreds of OSINT-related websites, tools, and services. The list covers a wide range of categories including search engines, social media tools, domain and IP research, people investigations, email search, phone number research, threat intelligence, and more. It is maintained by the community through pull requests and follows the awesome-list format. As a curated list, there is no executable code, no data ingestion, no transformation logic, and no analytical models. The value lies in the curation and organization of resources. The repository is primarily a reference for OSINT practitioners, researchers, and security professionals. While not a traditional software project, the list is well-structured and actively maintained. It can be easily cloned and used offline. However, from a software engineering perspective, there are no reusable components or architectural patterns to evaluate.
