Welcome to Bellingcat’s Online Open Source Investigation Toolkit!

Your go-to resource for discovering open source research tools! Our toolkit includes satellite and mapping services, tools for verifying photos and videos, websites to archive web pages, and much more. Most of the tools that we include can be used for free.

Our Toolkit Maintainers and Guardians

Bellingcat’s Online Investigation Toolkit has a long tradition but our newest version is special: It is offered in collaboration with the Bellingcat volunteer community.

Bellingcat volunteers, staff and the wider open source researcher community contribute to writing and updating toolkit descriptions. Bellingcat staff checks each toolkit entry before it goes online.

If our Toolkit Maintainers choose to be publicly mentioned, you can find their names on individual tool pages under "page maintainer".

Our Toolkit Guardians have a special role: They help us further develop this toolkit to make sure it meets the needs of open source researchers.
