3-Step Setup

1

Build your wheel — no account needed

Go to FateWheel's homepage and build your wheel — add your entrants, customize colors, and adjust the spin duration. No sign-up required to get started.

2

Click Embed and copy the Stream Overlay URL

Click Embed, then copy the Stream Overlay (OBS) URL from the popup. The URL looks like: fatewheel.com/stream/custom?d={payload}&bg=00ff00

3

Add a Browser Source in OBS

In OBS or Streamlabs, add a new Browser Source. Paste the stream URL, set the size to match your canvas (e.g. 800×800), and apply a Chroma Key filter selecting the green color. The background vanishes — the wheel floats over your scene.

Frequently Asked Questions

Does this work with Streamlabs as well as OBS?
Yes. Streamlabs OBS and obs-studio both support Browser Sources and Chroma Key filters in exactly the same way. Add the stream URL as a Browser Source in either app, then add a Chroma Key (or Color Key) filter to the source. The process is identical.
Can I use a background color other than green?
Yes. Append ?bg=RRGGBB (no #) to your stream URL to use any hex color as the background. For example, ?bg=ff00ff gives you magenta. Pick a color that does not appear in your wheel segments to avoid clipping. The default is ?bg=00ff00 (green).
Do spins in the stream overlay count toward my dashboard stats?
It depends on the URL type. Spins on a custom (unsaved) stream URL are not recorded anywhere — they're just for you and your audience. If you save your wheel with a free account first, its permanent stream URL does record every spin to your dashboard stats.
Does the stream wheel work for Twitch giveaways?
Absolutely. Type your entrants' names into a wheel on FateWheel, click Embed, and copy the Stream Overlay URL. When you're live, click the wheel (or press Space/Enter) to spin. The winner banner appears for about 6 seconds so your audience can clearly see the result before it fades.
Is this feature free?
Yes, completely free. FateWheel has no premium tier — the stream overlay, embed codes, and all other features are available to every user at no cost, with no account required. Saving your wheel with a free account is optional — it upgrades your custom URL to a permanent short link with live spin stats on your dashboard.
