Stand by. Go.
A cue board that runs in a browser tab. Every sound and every slide in your show sits in one numbered list, and one keypress sends the next thing on it to a second screen the audience sees.
Nothing plays on a timer. Nothing plays until you call it.

School and community productions run on whatever is to hand: a laptop with a media player, someone scrubbing a timeline in the dark, a slide deck in another window and a phone with the script on it. Four things to watch, four things to get wrong.
A professional desk solves this by holding the sequence and letting one person call it. That is the only part CueFlow copies. It keeps the list; you keep the timing.
One library, four kinds of thing. Audio, images, video and typed slides, with a real editor for each, trim and level a sound, crop and grade a picture, cut a video down to the eight seconds you need, compose a title card. All of it happens in your browser. Nothing is uploaded to be processed.
Two runs of numbers. Sound counts 1, 2, 3. Anything the room sees counts a, b, c. "Play 3"
and "put up b" can never be confused over comms, which is the entire reason theatre numbers them
separately.
Cues that fire in pairs. Link a slide to the sound underneath it and one keypress sends both, while the deck's position stays on the cue you actually called.
A script that warns you. Import a Word or PDF file and it keeps the writer's formatting and loses the paper. Name the words that matter and the screen flashes amber shortly before each one arrives, then red as it lands. Never a sound, you are standing a few feet from an audience.
Shows across every device in the room. Hand out a key and the rest of the crew join on their own phones. No accounts. Each job's key decides what that person sees and can do; the show password gets you in as a collaborator. Messages between devices flash on screen and are silent by design.
Projects. A separate library, sequences, script and shows per production, with collaborators added by username or email.
CueFlow is designed for dark rooms, quick handoffs and screens that stay legible when the show is moving. These are the working app screens in the dark theme.
npm install
npm run devCopy .env.example to .env and fill in a Supabase URL and publishable key if you want accounts and
cloud sync. Without them everything still works, saved to the browser.
npm test # vitest
npm run build # production bundle into dist/React, TypeScript, Vite, Tailwind v4 and HeroUI. Web Audio for the sound editing, Canvas for the
pictures and slides, pdfjs and mammoth for script import, Supabase for accounts, storage and the
realtime channel a show runs on.
The editors were built by studying how the good open-source tools behave, not by copying their code they are GPL and this is not, so the debt is behavioural, and it is acknowledged in full on the Credits page: Audacity and Audiomass for the sound editor, darktable and Krita for the order and naming of the picture controls, OpenCut for the video trim, pptWeb for the slide composer.
