9 free OSINT tools that actually work.

Start every investigation here: orient yourself visually before running a single query. See the location, what's around it, what's moving through it — flights, satellites, ships, weather, ground cameras — all free with no account. The visual layer most free OSINT stacks are missing.

Free-tier reality: Free tier: the entire live map — globe, flights, satellites, ships, weather, quakes, fires, ~36,000 cameras — no signup, no paywall. OSINT toolkit and AI analyst are Pro.

Machine-coded world news events in 100+ languages as open data. For quantitative OSINT — tracking event intensity, mapping coverage patterns — it's the most powerful free dataset in existence. The price is learning to query it.

Free-tier reality: Free: the full event datasets, updated every 15 minutes, queryable via BigQuery. Requires data skills — no point-and-click interface.

The best-curated free starting library in open-source investigation, maintained by the team that defined modern OSINT methodology. Organized by investigation type — geolocation, social media, imagery verification — with guides written by practitioners.

Free-tier reality: Free: the entire curated toolkit and methodology guides. It's a library, not a single tool — you still run the tools yourself.

Automated reconnaissance across 200+ data sources from a single target: IPs, domains, emails, names, breaches. The open-source workhorse for footprinting — powerful, free, and honest about needing a human in the loop.

Free-tier reality: Free and open source to self-host. Output volume is high — you supply the analyst judgment to separate signal from noise.

The classic first step in external footprinting: gather emails, subdomains and hosts tied to a target from public sources. Free, scriptable, and still in daily use by professionals who could afford anything.

Free-tier reality: Free and open source, command-line. No GUI — but simple enough that the terminal shouldn't scare you off.

The search engine for internet-connected devices. Even the free tier teaches you the fundamental OSINT lesson — how much infrastructure is unintentionally public — and handles small research tasks genuinely well.

Free-tier reality: Free tier: limited searches and results. Enough to learn the tool and run small investigations; serious use is paid.

The industry-standard link-analysis workbench, in a free edition that teaches the real methodology: entities, relationships, graphs. Start here before spending anything on investigation platforms.

Free-tier reality: Free Community Edition with limited transforms and graph size. Enough to learn link analysis properly before deciding if you need the commercial platform.

The Internet Archive's record of the web across decades — deleted pages, changed claims, vanished profiles. For establishing what someone said before they edited it, nothing else exists at this scale, and it's completely free.

Free-tier reality: Free: the full archive. Coverage varies by site and era — some pages were never captured, and that's just how archives work.

Authoritative, free, minute-fast seismic data from the European-Mediterranean Seismological Centre and USGS. For disaster OSINT and verifying shaking-related claims, primary-source data beats every aggregator — and it's open to everyone.

Free-tier reality: Free: authoritative real-time feeds. Scope is earthquakes (and related hazards) — narrow by design.
