Every supporter, every tier.
Any donation — one-time or monthly, any amount — turns these on for your account.
Ad-free experience
No curated recommendations on rules or tools pages. Free pages show one small, sport-relevant ad slot; supporters see nothing.
Refined export chrome
PDF, PNG, and iCal exports from Bracket Generator, Scoreboard, and Round-Robin show less OSS branding — more room for your content.
10 MB roster imports
CSV, TSV, or paste-in on Team Generator, Scoreboard, and Round-Robin. Free tier caps at a smaller size.
Our four commitments.
Rules stay free
No paywall on any sport, ever. Every rulebook is public, indexed, and free to read.
No third-party ad scripts
We may show curated, sport-relevant recommendations on free pages — never pop-ups, never behavioral tracking, never cookies. Supporters and Patrons see no ads at all.
Transparent costs
Every dollar of infra spend is line-itemed below. We'd rather over-state our costs than mislead.
Community-driven
Features are built for athletes, coaches, refs, and fans — not advertisers.
