JDR Ninja

JDR Ninja Overlay

A transparent OBS overlay that shows your dice rolls live during your games. Twitch chat commands are free, while Foundry and Stream Deck come with a subscription.

How it works

  1. 1

    Create your overlay

    Generate the OBS browser-source URL from the configuration, in seconds and without copying any password.

  2. 2

    Add it in OBS

    Paste the address into a “Browser” source. The overlay stays transparent and ready to animate your rolls.

  3. 3

    Link your sources

    Connect your Twitch channel for chat commands, which are free. Link Foundry too (and soon Stream Deck), then send your rolls live with a subscription.

  4. 4

    Roll the dice

    Every recognized roll animates automatically on the overlay, then disappears after the duration you choose.

Your roll sources

Twitch chat

Free

Your community rolls dice in your chat with the commands you define, and the result animates on the overlay. Available on every account.

Foundry VTT

With a subscription

The JDR Ninja module relays your real Foundry rolls to the overlay, without copying any password. Pairing stays free; live rolls require a subscription.

Stream Deck

Coming soon

A future Stream Deck button will send your rolls straight to the overlay. It will need a subscription, on the same terms as Foundry.

Frequently asked questions

Do I need a subscription to use the OBS overlay?

No. Creating the OBS browser source URL, copying it, regenerating it, enabling or disabling the overlay and running the visual demo all stay free, as do the Twitch chat dice commands. A paid subscription covers live rolls sent from Foundry or Stream Deck, draws from your Foundry tables triggered in chat, and priority, continuous reading of your Twitch chat.

How do I add the overlay in OBS?

From the configuration, create the browser-source URL, copy it, then add a “Browser” source in OBS with that address. The URL is shown only once: regenerate it if you need to copy it again.

Does the demo send a real command?

No. The demo builds a fake roll directly in the page and animates it locally. It calls no server, broadcasts nothing to OBS and does not depend on your subscription.

What if I share or export my OBS scene?

An exported OBS scene collection contains the overlay URL. Treat it as a secret: if it leaks, regenerate the URL from the configuration. The old address and its connections then stop immediately.
