Open Source • Free • GPL-3.0

Karaoke hosting that
actually plays fair.

Built by a KJ with 25 years in the trenches. The Rotation Fairness Engine keeps every singer heard, every turn earned, every show honest. No other karaoke software does this.

25 Years KJ Experience
0 Dollars to Start
Fairer Shows

Born from Kircher Entertainment — 25 years of live karaoke shows in the Philadelphia area. Every feature exists because a real KJ needed it on a real stage.

Everything a KJ needs.
Nothing they don't.

Professional karaoke hosting with built-in streaming controls, intelligent fairness, and the flexibility to run your show your way.

🎛️

Built-in Streaming Controls

Control Spotify, YouTube Music, and iTunes right from the UI. No app switching. Manage break music without ever leaving your hosting screen.

🎵

Every Format You Need

CDG, MP3+G, MP4, mkv — play them all. Key changer, tempo control, EQ built in. Your library works here.

🔇

Break Music Auto-Fade

Break music fades out when the singer's track starts, fades back in when it ends. Seamless transitions. No dead air.

💾

Automatic Backups

Timestamped database backups with automatic pruning. Your show data is safe even when hardware isn't.

🔓

Free & Open Source

GPL-3.0 licensed. No subscriptions for the desktop app. No lock-in. Inspect the code, contribute, or self-host the server.

Every singer gets their turn.
Automatically.

The #1 reason KJs switch to Auto-KJ. No other karaoke software enforces fairness. This changes everything.

01

Round-Based Turn Tracking

The engine tracks when every singer has completed their turn. When the last singer in the round performs, the round auto-advances and everyone starts fresh. No singer gets a second turn before everyone else gets their first.

02

Duplicate Turn Prevention

When a singer tries to add a second song in the same round, the KJ gets an immediate warning: "This singer has already performed — 4 singers still waiting." You can still allow it, but you'll never accidentally let someone cut the line.

03

Smart Song Blocking

Once a song is performed tonight, it's blocked — even if someone picks a different version. "Don't Stop Believin' [Karaoke Version]" and "Don't Stop Believin' (In the Style of Journey)"? Same song. The engine knows.

04

Singer Alias Detection

"Mike," "Michael," and "Mike S." — all the same singer. The alias system resolves alternate names to a single identity. No gaming the rotation by signing up under a different name.

05

DJ Override — You're Still the Boss

Fairness rules are enforced, not imposed. The KJ can override any block with a single click — birthday requests, encores, whatever you need. Overrides are tracked per-singer, per-song. You stay in control.

Your singers have phones.
Use them.

The free desktop app runs the show. The optional server connects your singers — requests, rotation display, check-ins — all from their phone.

📱

Singer PWA

Singers scan a QR code, open their phone's browser, and they're in. Request songs, see the rotation, check in for the night. No app to install.

🔔

Now-Playing Push

Singer gets a notification when they're up next. No more "when's my turn??" interruptions. They know. They're ready.

Check-In System

Singers check in on arrival. The fairness engine knows who's actually present — no-shows don't block the rotation.

🏢

Venue Management

Track shows per venue, singer history, and gig stats. Running multiple venues? Everything stays organized.
