What it does

A control room for your campaign.

Everything a Dungeon Master needs to direct a cinematic, fully-synced session — without juggling tabs.

Scene decks

Build cinematic scenes with music, ambience, video and SFX — triggered with one click.

Real-time sync

Every player hears and sees the same moment. Crossfades, transitions and timers travel together.

YouTube integration

Drop a link, assign to a scene. Official iframe API — no downloads, no copyright drama.

Layered soundboard

Sword clashes, dragon roars, rain — instant playback with hotkeys and layered mixing.

Cinematic crossfades

Hand-tuned transitions between scenes — music, ambience and visuals fade as one.

Guest rooms

Share a link or QR code. Players join in one tap — no account required.

Director hotkeys

Press 1 for Tavern, 2 for Combat, 3 for Boss. Conduct the room like a film score.

Immersive mode

Hide the UI. Fullscreen cinematic visuals turn any screen into a portal.

From idea to immersion in three steps.

No setup, no installs. Open a browser, become the director.

01

Drop YouTube links, ambience and SFX into beautiful scene buttons.

03

Direct the story

Trigger scenes with a click or hotkey. The whole table feels the moment.

Questions

The quick answers.

If anything's missing, just ask — we read every message.

Do my players need an account?+

No. Share a link or QR code and they're in. Accounts only unlock saved campaigns and reusable scene decks.

Does it work over Discord, Zoom or in person?+

All three. RealmCaster runs in any modern browser — perfect alongside Discord voice or around a single TV.

How does YouTube playback work?+

We use the official YouTube iframe API. Paste a link, assign it to a scene, and it streams legally to every connected player.

Is it really free?+

Yes. RealmCaster is free during early testing. We're focused on growth, immersion and community feedback — no paywalls right now.

How do I shape the roadmap?+

Head to the Community board. Post ideas, report bugs, upvote what matters — we're building this with storytellers, in the open.

Your next session
will feel like a film.

Open a room in 10 seconds. Bring your players in. Direct the moment.
