OpenIndex

OpenIndex is an open data infrastructure organization on Hugging Face that publishes large-scale community platform datasets in Parquet format under the ODC-BY license. Their flagship dataset is a complete, live-updated mirror of the Hacker News archive (47M+ items since 2006, refreshed every 5 minutes), alongside Reddit and Common Crawl datasets. The organization appears to be a solo project by Duc-Tam Nguyen with no external web presence beyond Hugging Face.
