One place for the
whole game.

Game day is scattered — group chats, creator feeds, prediction apps, and leaderboards that never connect. Sideline brings communities, creators, predictions, and competition into one home.

Not a sportsbook. Not another chat app. Join as a founding member while we're building — and get in before launch.

Why we built Sideline

One game shouldn't take six apps to follow.

Sports fans bounce between Discord, Reddit, podcasts, prediction apps, and creator feeds just to follow one game. Sideline is a sports platform that brings communities, creators, predictions, and competition together — not another chat app, forum, or sportsbook.

The Sideline Team
Our commitments

Built in public

We share what we're building and ship in the open with early members.

Community-first

Features come from real fan feedback — not growth-hacking playbooks.

Made by sports fans

We're building the home we always wished existed for following the game.

What Sideline is not

Not a sportsbook

Skill-based picks only — no betting, odds, or wagers.

Not Discord or Reddit

Built for sports — not a chat server or forum thread.

Not Patreon

Creators run communities with fans — not a one-way feed.

Communities

Find your people

From NFL film rooms to fight-night threads — a home for every team, league, and creator.
