Question 1

What is OsintLibrary?

Accepted Answer

OsintLibrary is a curated directory of Open-Source Intelligence (OSINT) tools for investigators, security researchers, and journalists. Every tool is tagged with the data it takes as input (email, username, IP, hash, etc.) and the data it produces as output, enabling automatic tool-chain discovery — the output of one tool becomes the input of the next.

Question 2

Are the tools listed free to use?

Accepted Answer

The catalogue mixes free, freemium, and paid tools. Each entry shows its pricing tier and whether it is open source. You can filter the browser to show only free or only open-source tools.

Question 3

How do I find tools for a specific investigation type?

Accepted Answer

Visit the /tools page and use the investigation-type filter — entries like email forensics, social-media OSINT, blockchain analysis, and DFIR. You can also start from the mind-map view to see how tools chain together by concept.

Question 4

Can I use the catalogue programmatically?

Accepted Answer

Yes — the public REST API at /api/v1 exposes every catalogue entry. CORS-enabled for read access, API-key auth available for higher rate limits. See the /api-docs page.

Question 5

How can I add a tool to the catalogue?

Accepted Answer

Submit it via the /suggest form. Submissions go through a moderation queue; once approved, the tool joins the active catalogue and shows up in search, the mind map, and the chain-discovery engine.

Every clue. Every tool. One library.
