Below is the structured data index showing the main open source intelligence (OSINT) resources and core utilities for specific intelligence verticals:

Open-Source Intelligence (OSINT) frameworks and repositories are organised platforms for gathering and analysing data that is freely accessible on the internet. There is no single, all-encompassing OSINT application. Rather, the OSINT landscape relies on large directories, automated correlation engines, specialised trackers and systematic analytical techniques to transform fragmented information into actionable intelligence.

Master Directories & Tool Repositories

These platforms function as interactive roadmaps to identify specific utilities for an investigation.

• OSINT Framework: An extensive, interactive tree directory that categorises public record tools, email lookups, IP tracking, and dark web resources.
• Awesome OSINT GitHub Repository: A massive, community-curated collection of open-source tools categorised by application type.
• OSINT Combine Free Tools: An updated index of localised platform trackers, geolocation tools, and bookmark stacks.
• Toddington International Resources: A highly professional database featuring online investigative aids and training cheat sheets

Multi-Source Aggregators & Visualisation

These systems consolidate data from hundreds of endpoints into visually mapped relationship networks.

• Maltego: A graphical pivot engine that maps data patterns and connections among people, domains, and organisations.
• SpiderFoot: An automation tool that scans across multiple data infrastructure sources to map an attack surface.
• theHarvester: A command-line tool built to gather emails, subdomains, hosts, and employee names from search engines. 

Specialised Investigative Pillars

Depending on your intelligence objective, use these target-specific frameworks.

Primary Resources

Core Investigative Utility

Identity & Accounts

Epieos, WhatsMyName

Cross-referencing email IDs, usernames, and profile linkages.

Geospatial & Transit

FlightRadar24 is a live universal awareness map.

Real-time aircraft tracking and geolocated event tracking.

Corporate Tracking

OpenCorporates, OpenSanctions

Corporate ownership registries and international sanctions databases.

Advanced Web Intel

Google Hacking Database, Shodan

Utilising Dork syntax to index unsecured network hardware is a key technique.

Practical Training & Analytical Methodologies

True OSINT requires structured interpretation over passive data gathering. 

• OSINT Dojo: A free, open-source practical learning platform offering hands-on investigative scenarios.
• Michael Bazzell’s IntelTechniques: The industry-standard authority for privacy, security, and digital data preservation guidance.
• Structured Analytic Techniques Primer (PDF): A publication that details standard analytical intelligence practices to minimise personal cognitive bias.
