Welcome to Bellingcat’s freely available online open source investigation toolkit. You can follow our work via our website, Twitter and Facebook. (We also provide three to five day open source investigation workshops.) This is version 5.3 (August 19, 2020). The list includes satellite and mapping services, tools for verifying photos and videos, websites to archive web pages, and much more. The list is long, and may seem daunting. There are guides at the end of the document, highlighting the methods and use of these tools in further detail.
