Hey PH! I'm Jon, solo indie dev. I built Beltr because every karaoke app I tried was either subscription-based, required a specific song catalog, or couldn't work offline. I wanted to sing MY songs at house parties without paying $15/month forever.
The AI separation (Meta's Demucs v4) runs locally on your machine — your music never leaves your computer. Guests connect phones by scanning a QR code on the TV. No app download needed.
Launch price is $19.99 (normally $29.99) through April 15. Try 5 songs free, no credit card.

Who hunted Beltr?
Beltr was hunted by Jonathan Vargas. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
