Bulk domain rating data for 222,825,218 domains, back to 2017

Every domain we rate, with its rating, raw score and link counts, as a parquet file per monthly release. Every month back to 2017, and every new release as it lands.

What you get

  • • One parquet file per release, named after the month (2025-12.parquet).
  • • Every monthly release back to 2017, not just the current one.
  • • Over 200 million domains in the latest release, one row each, sorted by domain and ZSTD compressed.
  • • Direct download links, no rate limit, no charge per person.
  • Code for opening the files in SQL, Python, R, Ruby, JavaScript, Go, Java, Rust and C#.
  • • New releases appear on their own, roughly monthly.
  • A way for your own software to fetch them, so collecting each new release can be automatic.
