soundcn

soundcn is an open-source collection of more than 800 sound effects for web apps, mostly CC0-licensed sounds from Kenney, each installable into a project with a single shadcn command. Sounds are grouped into categories such as UI, feedback, game, impact, sci-fi and retro, and every card lists its length and file size, so a 1KB back click is easy to tell apart from a longer fanfare. Turn to it when an interface needs a click, confirmation or error sound that is licence-clear and only a few kilobytes.
