From public data checked . How we know
Choose nflverse if you…
Free / open data
Best for: Analysts and modellers who want free NFL play-by-play since 1999 and stats via R and Python packages.
- ✓ need American football
- ✓ need commercial use allowed in the public terms
- ✓ value a large open-source ecosystem of wrappers and examples
Not ideal for: Live apps needing real-time feeds or a hosted REST API; data is distributed as files through loader packages.
What developers say
Open-source NFL data (play-by-play, rosters, schedules, player stats) distributed as files with R and Python loaders, under CC-BY. Widely used by fantasy dashboards, dynasty tools, waiver-wire content and sportsdataverse packages; chosen as a free primary source or schedule fallback. Not a live REST API, so real-time needs require other providers.
Choose Retrosheet if you…
Free / open data
Best for: Baseball researchers and hobbyists who want free bulk MLB play-by-play, game logs and schedules as downloadable CSV files.
- ✓ need Baseball
Not ideal for: Apps that need a live API or current-day data; Retrosheet offers bulk file downloads only, with a copyright notice on the data.
What developers say
Volunteer-run archive of MLB play-by-play, game logs and schedules as downloadable files, not a hosted API. Recommended on HN and betting forums for model building and ETL practice, and widely used by tools such as Chadwick and boxball Docker images. Free and deep history back to 1914; you must parse and host it yourself.
