Show HN: Bracket – selfhosted tournament system (❄️ Score: 150+ in 2 days)

Link: https://readhacker.news/s/6tXhs
Comments: https://readhacker.news/c/6tXhs

Over the last two years, I developed a tournament system called Bracket.
Most (if not all) tournament systems available online are paid and ask tons of money (a typical minimum subscription costs 50 euros per month, and go up to 500 euros per month or so), which is not feasible for many small sport clubs/individuals. So I developed my own system and put it publicly on GitHub. AFAIK this is the only open source tournament system available that has a significant amount of features.
I made this tournament system for my badminton club and hosted six paid tournaments successfully.
It features flexible setups, where a tournament can have multiple stages and each stage can have multiple "items" (round robin, single elimination or swiss).
Backend is written in async Python with FastAPI and frontend in Next.js with the great Mantine library.
I would appreciate some feedback!

Hey everyone! I'm the current maintainer of KCC since 2023, thanks for using it! I’ve been reading manga on Kindle ever since I got the big 9.7” Kindle DX from 2010 using mangle, and upgraded to the even bigger 10.2” Kindle Scribe 2022 using KCC.
The biggest contributions I've made to KCC are:
- added modern macOS support and removed homebrew requirement
- ported code to run on native Apple silicon M1 chip and later for a 2x speed boost (qt5->qt6)
- free open source windows codesign with SignPath - fixed Kindle Scribe support
- and tons of other various features and bug fixes and developer friendly changes
- created a legacy Windows 7 build with 300+ downloads…
The biggest community PRs were:
- huge 2x speed boosts due to various CPU/IO optimizations
- Kobo/Remarkable support
Enjoy using KCC and let me know if you have any questions!
