Joak's osu mirror download is a lightweight Chrome extension designed specifically for osu! players. With this extension, players can easily download beatmaps from various third-party mirror APIs without the need to manually visit those sites or install any additional applications.

One of the key advantages of this extension is that it significantly improves the download speed compared to the official osu! site. This is particularly useful for multiplayer rooms where players often need to quickly download beatmaps. Additionally, the extension eliminates the need to sign in to download maps and provides access to beatmaps that may not be available on the official site.

The extension supports three popular third-party beatmap mirror download APIs: Chimu, Kitsu (Osu direct), and Nerinyan. It also includes a convenient button for beatconnect link for each map. To enhance user experience, the extension can be pinned to the browser for quick API switching.
