A marketplace for finding, subscribing to, and using third-party data inside the AWS cloud. It carries both free open datasets and paid commercial data products, so you can pull licensed data straight into your AWS workflows without setting up separate transfers.
A registry of high-value datasets hosted on AWS and made publicly available, covering genomics, geospatial data, climate, satellite imagery, and more. Over 300 PB of data in total, free to access: you pay only for the compute you use to process it.
A platform for publishing and finding open data packages: datasets bundled with consistent metadata in standardised formats. It hosts curated collections of widely used reference data, from country codes to exchange rates, ready to drop into a pipeline.
A search engine for datasets that indexes millions of them from thousands of repositories worldwide. It does not host data itself: it points you to wherever each dataset lives, which makes it a fast first stop when you are hunting for a source on a specific topic.
The largest open hub for machine learning datasets, with well over 100,000 datasets you can search, stream, and version. Many RAG-ready corpora live here, and its Python library lets you pull data straight into a pipeline in a few lines.
A hub of user-contributed datasets spanning almost every domain, owned by Google. Alongside the data you get notebooks, competitions, and active discussion, which makes it a quick way to find something workable and see how others have already cleaned and used it.
A data marketplace connecting more than 820 providers who offer over 3,400 live datasets, data services, and applications. Listings span financial, weather, demographic, and industry data, with a mix of free and paid options delivered straight into a Snowflake account.
A general-purpose open repository built by CERN where researchers can deposit datasets, software, reports, and any other digital output. Every upload gets a DOI, a permanent identifier that makes the work easy to cite and find again, which makes Zenodo a reliable long-term home for research data.
