With Friends is one of two online multiplayer modes in Super Smash Bros. Brawl and Super Smash Bros. 4, the other being With Anyone. In this mode, the player can only play with players registered on their friend roster. In Brawl, this is the only online mode where records are kept and names can be seen. Opponents will be able to see the player's profile icon and comment before battle. In Ultimate, this was feature was replaced with Battle Arenas, which allows the creation of password and friend-limited arenas.
Regular versus mode matches can be played with all the usual options, but Special mode and 8-Player Smash are not available. Players can set short custom messages to appear when they taunt in a With Friends match. In Brawl, Home-Run Contest and Multi-Man Smash could also be played. In Super Smash Bros. for Wii U, voice chat can be enabled in With Friends, using the Wii U gamepad's microphone.
Various websites, such as All is Brawl, Anther's Ladder, and Smashmate, would be created to make use of With Friends matches, serving as an alternative to the usual rulesets Brawl and Smash 4 use, which were often seen as flawed and uncompetitive. These websites would often host rated ladders as well, allowing for more high-stakes matches to be played by more serious players.
