As answered by people managing Opalstack and HoneyCup.ru.
HoneyCup.ru's answer:
I started HoneyCup after watching three amateur tennis clubs run tournaments on paper and Excel. Bracket generators existed (Challonge, Toornament), but every useful format — double elimination, Swiss, groups — was paywalled, required signup, or didn't print to A4 cleanly. Coaches were spending evenings on math instead of coaching.
The first version was a Russian-language single-sport (tennis) round robin generator built in 2024. Clubs adopted it, asked for double elimination, then chess players found it, then padel coaches. By 2026 it had grown into a 7-sport, 6-format, bilingual platform — still free, still no signup required, still optimised for the "Saturday morning before the tournament" use case.

Common trait: previously used Excel, paper, or hit Challonge's paywall. Want a bracket in five minutes, not a CRM.
HoneyCup.ru's answer:
No-signup, no-paywall bracket generator with the broadest format coverage of any free tool: 7 sports × 6 formats (single elimination, double elimination, round robin, Swiss, groups + playoff, groups + double elimination) = 252 ready-to-use templates, all printable as A4 PDF. Most competitors gate Swiss, double elimination, or more than 8 players behind a paid tier — HoneyCup ships everything free, in five seconds, in browser, bilingual (RU/EN).
