Referee lights for your Powerlifting competition
A complete system connecting referees, display, timer, and live broadcasting in real time. Works on phones, tablets, or computers.
What is Referee Lights?
Referee Lights is a web platform that replaces traditional physical referee light panels. Each referee uses their own phone to vote (GOOD LIFT or NO LIFT), and decisions appear instantly on the main display — perfect for in-person or live-streamed competitions.
How to use in 5 steps
From zero to a running competition. No app install needed on referee phones.
Click "Create session now" above. The system automatically generates a room with a PIN and QR Codes for the referees.
Each referee scans their corresponding QR Code (left, center, right) with their phone camera. The referee console opens directly in the browser — no app download needed.
In the admin panel, click "Open Display" and put this screen on the projector or TV. Referee lights appear here in real time.
Referees vote on their phones. The lights (white = valid, red = invalid) appear on the display once all votes are in. Use the timer and intervals from the admin panel.
Open the Legend/Chroma Key screen and capture it in OBS Studio to overlay referee decisions on your live stream.

Frequently asked questions
What athletes and meet organizers usually ask before their first competition.
What is Referee Lights?
Referee Lights is a free referee light system for Powerlifting competitions that follows IPF rules. Three referees vote from their own phones (GOOD LIFT or NO LIFT) and the lights appear in real time on the venue display — no physical light panels and no app install required.
Is it really free? Is there a paid version or usage limit?
Yes, Referee Lights is free, with no sign-up, no session limit, and no premium tier. The source code is public on GitHub and free to use for athletes, clubs, federations, and non-profits; only commercial use (reselling it or offering it as a paid service) requires the author’s permission.
Do I need to install an app or create an account?
No. Everything runs in the browser: the organizer creates a session at refereelights.app and referees join by scanning a QR Code with their phone camera. There is no app download, no registration, and no setup.
Can it be used in official competitions?
The system implements the full IPF refereeing flow: three referees, lights, penalty cards, and official timing. Equipment approval for sanctioned championships is up to each federation, though — check with your event’s organizers before using it.
