Present from the browser.
No software to download. Kastr is an online application for live operators: setlists, lyric slides, media, and projection in one workspace.
Build the program, hit play, and every screen follows. Open a projection window here, or share a public link so phones and overflow rooms stay on the current slide.
Open a tab. Run the room.
Kastr lives in the browser, so the operator desk, the projector, and overflow screens all follow the same set. No installer. No local copy to keep in sync.
Built for the person at the desk.
Previous, next, blackout, and last-minute lyric edits stay on the operator surface. The house only ever sees the current slide.
One link for every screen.
