Beatmap submission (lazer)
Note: For the osu!(stable) version of this article, see Beatmap submission
Beatmaps can be submitted to the osu! website via the in-game editor. Submitting a beatmap allows it to receive attention from other users and potentially enter the Ranked or Loved categories. The infrastructure facilitating this is commonly called the Beatmap Submission System (BSS).

Beatmap submission
Selecting Submit beatmap from the File dropdown in the editor (shortcut: Ctrl + Shift + U) will open the beatmap submission screen. This screen provides options for which beatmap category the map should end up in, whether to enable discussion notifications and whether to open the uploaded map in the browser. If you encounter trouble when using BSS, please ask in the Help subforum.
Limitations
Beatmaps will fail to submit if they exceed the online file size or difficulty limit. The file size limit is 5 MB plus an additional 10 MB for every minute of beatmap length, and it caps at 200 MB. The difficulty limit is currently 128.
Users are allowed a limited number of pending beatmaps at a time. The limit varies depending on how many ranked beatmaps a user has and whether or not they are currently an osu!supporter. Users without osu!supporter can have 4 pending beatmaps plus 1 per ranked beatmap (up to 4). With osu!supporter, this increases to 8 pending beatmaps plus 1 per ranked beatmap (up to 12) for a total of 20.
