Sideline Social

What it is

All your teams. All the time.

Sideline Social is a social network built only for sports fans. Your home feed is a real-time, Twitter-style timeline of your teams — news, takes, and the people who follow the same games. When a game goes live, a dedicated room opens, synced to the score, so you can react to every play with everyone else watching.

How it works

From your feed to the final whistle.

01

Pick your teams

Choose who you follow across MLB, NHL, and NBA. Your feed fills with their news, takes, and games.

02

Live in the feed

A real-time home timeline of your teams and the fans who never stop talking about them — every day, not just gameday.

03

Drop into the live room

When the game's on, jump into a room synced to the score and react to every play with everyone watching.

FAQ

Questions, answered.

What is Sideline Social?
