Research starts with the right source.
Razib Internet Index organizes tools and reference sources for open-source intelligence (OSINT), public-record research, social-platform research, geography, and technical investigation. It is a starting point for choosing sources, rather than an endorsement of every provider.
Curator and contact
The directory is maintained by Razib. To suggest a resource, correct a description, or report a broken link, email razib@live.co.uk. Include the category, tool name, destination URL, and a short explanation.
Selection and maintenance
Listings are grouped by their stated purpose. Summaries help identify the task a resource may support; they are not claims that every external service has been independently tested. Pricing, account requirements, geographic coverage, and availability remain with the provider.
- Keep category descriptions clear and tool names recognizable.
- Remove accidental duplicates within a category. A resource may appear in several categories when relevant.
- Prefer official sources and HTTPS endpoints where confirmed.
- Reassess misplaced or unclear listings when reports or reliable source information become available.
This version of the directory was revised on . That date describes changes to the directory, not a fresh verification of every provider. There is no promised review schedule.
Using the directory
Search by name, topic, category, or words in the summaries. Search covers all categories. Tool links open in a new tab; category links stay on this site. Some older links use HTTP and are labeled. Specialist destinations may need a separate application or network.
Privacy
The supplied site has no analytics, advertising scripts, forms, cookies, or account system. Search runs locally in your browser and is also reflected in the page URL, so a search URL can be copied or bookmarked. Your host may keep normal access logs.
Fonts are loaded from Google Fonts. Opening an external tool sends a request to that provider, whose own privacy policy applies. External tool links use noreferrer and noopener.
Responsible research
Use resources for authorized, lawful research, respect personal privacy, and verify important findings against original sources. A listed result is not proof of identity or wrongdoing.
