Open-source show tools
Free utilities built backstage, for backstage — timers, show status pages, rundown sync, and comms control. Most are a single HTML file: no install, no build, no accounts.
Audio/video sync checker. Drop a recording of a clap, step to the frame where the hands meet, click the spike on the waveform, and get the exact vMix Audio Delay change in milliseconds. Nothing is uploaded — the file never leaves your browser.
Your show flow lives in a Google Sheet; your timers live in Ontime. Fetch the sheet, preview exactly what will change, and push it to all of your Ontime instances in one click — no retyping, no CSV exports.
Fullscreen AUX timer confidence monitor for Ontime — giant countdown, NOW/NEXT cue bar, presenter messages, blink and blackout, host heartbeat. Works with Ontime v3 and v4.
A mobile-friendly, client-facing live show status page — expected and actual start and end times, a show timeline, and an ahead/behind schedule indicator. Share the link; clients stop asking.
Bitfocus Companion module for the Clear-Com FreeSpeak II base station (FSII-BASE-II) — comms kill switch, RMK, GPO/GPI, and port gain. Drives the CCM REST API; no Clear-Com license needed.
Bitfocus Companion module for Internet Clicker — trigger slide advances and remote cues from your Stream Deck alongside everything else in the rig.
Most tools are a single HTML file. Open it in a browser, point it at your Ontime server, done.
Made during real shows to solve real problems — then cleaned up and shared so you can skip the pain.
Free to use, fork, and adapt. Issues and pull requests are welcome on any repo.
Everything here is free and MIT licensed, built between shows. If one of these tools saved your rehearsal, your stream, or your sanity, a coffee keeps the next one coming.
