start.gg
start.gg, formerly known as smash.gg, is a website that provides tournament organizing tools for event organizers within the esports community. The website was launched in 2015 and features the ability to host registration, form a bracket, and create rankings amongst other things. In addition, its API is publicly accessible, making it easy for other databases, such as supermajor.gg, and applications to retrieve tournament information from the website with ease.
start.gg has been the most popular and widely-used platform for hosting Smash tournament information and brackets since the late-2010s, surpassing earlier alternatives such as Challonge, and as such is often considered the norm in the competitive scene.
The website was acquired by Microsoft on December 2nd, 2020 following a continued history of collaboration between the two.[1] The website went independent on January 31st, 2025.[2] While the website initially only supported games within the Super Smash Bros. series, it has since then expanded to a plethora of other games with competitive scenes, eventually leading to its rebranding to "start.gg" on May 16th, 2022 to represent this expansion.[3] Among the games featuring a competitive scene and being featured to events in the website, the list ranges from traditional fighting games, both 2D and 3D, such as Street Fighter, Tekken, Fatal Fury and its successor The King of Fighters, Virtua Fighter, to platform fighting games like Rivals of Aether, to other video game genres such as Splatoon, Pokémon, Mario Kart and Mario Party, and lately Masahiro Sakurai's non-Super Smash Bros. games such as Kirby Air Riders.
