Your record
is lying
to you.
True Champion replays your season against every schedule and shows who actually deserves their record. All-play. Schedule swap. Head-to-head vs everyone. Then it emails the whole league every Tuesday.
No account. No cookies pasted. Read-only, always.
The math your
commissioner
won’t run.
Every week, every team plays every other team on paper. Win more of those than your real record says? Robbed. Fewer? The schedule is carrying you, and now everyone knows.
Three taps, one league-wide argument
01
Paste the link
Sleeper link, Sleeper username, or ESPN link. We pull the season in a few seconds. No sign-up.
02
Share one join link
Drop it in the group chat. Everyone taps their own team and enters their own email. You never type a thing.
03
Tuesday Reckoning
Every Tuesday morning the whole league gets the week’s frauds, robberies, and true standings.

Read-only by construction: we never touch rosters, lineups, or trades. The adapters can only call read endpoints.
The ESPN extension,
plainly.
Private ESPN leagues hide their data behind your login. ESPN keeps that login in two browser cookies no website can read, so the only honest shortcut is a small extension that runs in your own browser. Here is exactly what it does.
Reads two cookies, nothing else.
espn_s2 and SWID from espn.com. No browsing history, no other sites, no page content.
Only when you click.
It does nothing until you press Connect ESPN on this site, and it only answers pages on this site.
Sends them here, once, over HTTPS.
Straight to this site's connect endpoint with a single-use token. Never stored in the extension, never logged.
Checked, encrypted, auditable.
We verify the cookies against your league before saving, encrypt them at rest, and show you every use in Settings.
Open source, MIT, no analytics, no remote code.
