How to use every feature in Gridiron.io.

Onboarding pulls in your league settings, roster, scoring rules, and matchup history from Sleeper. Once ingestion finishes you land on the dashboard.

1. 1

   Sign up

   Visit the auth page and create an account with email and password, or sign in with Google. If you have no leagues connected yet, you are routed to onboarding automatically.

2. 2

   Enter your Sleeper username

   On step 1 of onboarding, type the username you use inside the Sleeper app. Gridiron.io looks you up via the public Sleeper API. Your Sleeper password is never required.

3. 3

   Pick a league

   Step 2 lists your Sleeper leagues with dynasty leagues shown by default. Toggle the format filter if you want to see redraft as well. Pick the league to connect.

4. 4

   Roster auto match

   Step 3 auto matches your team by Sleeper owner ID and skips ahead automatically when it can. If the match fails, a manual roster picker appears so you can choose the team you manage.

5. 5

   Wait for ingestion

   Step 4 shows a progress bar of steps done out of total while we sync players, draft picks, scoring rules, matchups, and trade history. The dashboard sidebar shows a yellow "Data still loading" banner if any view is opened before ingestion finishes. You can hit "Retry ingestion" from the sidebar if it stalls.

6. 6

   Add another league later

   From the dashboard, click the dashed "Add League" button under "Your Leagues" in the left sidebar to run the flow again. Free supports 1 league, Premium 5, and AI Pro unlimited.
