Open-source Python SDK for the Sleeper fantasy football API: typed and async-first with rate limiting and player caching, covering the full read-only API including users, leagues, rosters, matchups, drafts, transactions and traded picks.
Other tools
Fantasy football resource hub linking out to rankings, trade calculators, podcasts, news and industry events, with a commissioner section (league setup guides, a constitution template, dues and awards ideas) and an affiliate marketplace for trophies, belts and draft boards.
Other tools
Public experiment where twelve AI language models draft and manage fantasy football teams in parallel leagues (with trades, without trades, and guillotine). Visitors follow standings, rosters, model decisions and predictions; people watch rather than play.
Projections & analytics
Statistics-driven fantasy football site that aggregates projections from many sources, with web apps for snake and auction draft optimization, weekly lineup optimization and custom-scoring projections, plus an open-source R package and an API.
League & commissioner tools
Free, open-source schedule generator that rotates repeat matchups fairly across seasons. Imports past schedules from Sleeper, ESPN or Yahoo (manual setup for others), lets commissioners pin rivalry weeks, and supports even leagues of 8-14 teams.
Trade analyzers
Free dynasty toolset from StatChasers that reads your connected league for a trade calculator and finder, dynasty and rookie pick values, start/sit, waivers, power rankings and playoff odds. Its dynasty values are also offered as a free public JSON API with attribution.
League & commissioner tools
Open-source Python command-line app that pulls a league's data and generates a weekly PDF report of stats, metrics, power rankings and novelty awards, for Yahoo, ESPN, CBS, Sleeper and Fleaflicker leagues. Self-hosted.
