For developers, not managers
OPEN SOURCE.
RUN YOUR OWN
This whole league room is open source: GoSX server, snake draft, dynasty format, team-seat big boards, a player pool with optional live data, and a commissioner console. One Go binary, your own data, MIT licensed.
Three cost tiers
The corrected nflverse ledger gives next-morning truth for $0, with no live-data account at all. Tank01's free tier adds a $0 slow-live feed, about every 30 minutes on game days. Tank01 Ultra adds the 10-second live experience for about $25 a month for the whole league. The live feed only ever affects freshness — it never decides a closed week's score.
