Fishy

dev.fishy.moe is a special playground for testing & developing unreleased cheats to apply in future for kawata.pw. It runs a kawata backend with customizations from bancho.py-ex. The backend is fully reworked and rewritten for this purpose, so it stands as a "sister" build of kawata dedicated to testing.

To connect a cheat or osu! client for testing, launch osu! with the -devserver fishy.moe switch, then log in with your fishy.moe account. The server runs fully over HTTPS, so the client reaches it on the standard bancho subdomains without extra setup.

All of these clients are allowed: https://fishy.moe/client-cheating-archive

And Anything custom you can build/test or want to try out the server backend works with seasons so every year their are 3 seasons which means the leaderboard is constantly fresh but your total PP and Best is still gathered for an all time rank.
