Zenodo is a general-purpose open repository developed under the European OpenAIRE program and operated by CERN.

For each submission, a persistent digital object identifier (DOI) is minted, which makes the stored items easily citeable.

It was relaunched as Zenodo in 2015 to provide a place for researchers to deposit datasets;[6] it allows the uploading of files up to 50 GB.

[10] Zenodo is supported by CERN "as a marginal activity" and hosted on the high-performance computing infrastructure that is primarily operated for the needs of high-energy physics.

[15] Also in 2021, Zenodo reported it had crossed 1 Petabyte in hosted data and 15 million yearly visits.
