I’m Bartosz, and I build Stagelight: a free, open-source app that turns any song into karaoke on your own computer.

It started from a simple feeling: we spend more evenings talking to screens than to each other. Karaoke is one of the few things that reliably gets people off their phones, laughing and singing badly together, so I wanted to make it possible with any song, for free, without accounts or subscriptions.

Everything I build stays free and open source. Your coffee pays for the time it takes: the late nights fixing YouTube changes, testing on Windows, macOS and Linux, and new features like party mode and singing scores with a microphone.

If Stagelight made your night, thank you. That’s exactly why it exists. 🎤
