Finds published datasets across repositories, governments and journals.
A search engine indexing datasets rather than pages, built on the schema.org markup that repositories publish, so results carry licence, update date and provider. Filters for download format and usage rights are the part that saves real time when you need something you are allowed to redistribute. It only finds what has been marked up correctly, so plenty of good government data is simply invisible here, and it links out rather than hosting anything.
Questions
Works the moment the page loads. No account, no email, no trial. Only indexes datasets whose publishers added the right metadata — plenty of good data never appears.
Yes. Google Dataset Search sends your input to its own servers to process it. That is fine for public material; for anything containing personal data, use one of the on-device tools instead.
