Add Costream Override from the Chrome Web Store.

Pin or bookmark the extension so it is ready for every match day.

Paste the username above inside the extension popup and press save.

Watch on lolesports.com while earning missions and rewards automatically.

The site keeps counting rewards because you never leave the official page.

The Twitch player swaps to the username you configured on the extension.

You can remove or change the username inside the extension whenever you want.

Does this work on mobile?

Not yet. Costream Override requires the desktop version of Chrome or Edge.

Do LoL Esports drops still count?

Yes. You stay on lolesports.com the whole time, so drops, missions, and watch streaks keep tracking.

Is it safe?

All preferences stay in your browser. We do not collect data or require any external accounts.
