Three Ways to Run Your Draft

Pick the format that fits your league — from classic player auctions to creative number-based drafts.

Player Auction

Bid on individual players one by one. The classic format — nominate a player, set a minimum bid, and let the room battle it out until time runs out.

Team Auction

Bid on entire teams instead of individual players. Perfect for tournaments where you want to draft full squads against a shared budget.

Number Auction

Each number represents a player. A creative blind format that adds mystery and strategy — you don't know who you're bidding on until the hammer falls.

Built for Your League

Every Feature Your Auction Needs

From your first bid to the final roster, Auction League has it covered.

Instant Bidding

WebSocket-powered real-time bidding with sub-second sync. Every bid appears on every screen the moment it's placed.

Firebase Sync

All auction data is mirrored in Firebase so you never lose a session — even if someone drops out mid-auction.

Spectator Access

Invite unlimited spectators via a referral link. They can watch the bidding live without needing to bid themselves.

Budget Tracking

Each bidder's remaining budget is shown live. No overspending — the app enforces limits automatically.

Auctioneer Mode

One host controls the auction — nominates players, sets timers, and finalises each sale. Everyone else bids.

Offline Storage

Local SQLite cache means your roster history is stored even when you go offline after the auction ends.

How It Works

Your Auction, Ready in Minutes

Set up and launch a live auction before your league has finished ordering food.

Share the room code. Bidders and spectators join from their own devices instantly.

Start Bidding

Host nominates players, sets timers, and the room bids live. Every bid syncs in real time.

Build Your Squad

When the auction ends, every bidder's roster is saved. Your league is ready to compete.
