Audio-reactive visualizer overlay with real-time frequency bars and cinematic glow for your browser music.

Hey Product Hunt! Mak here, maker of WaveFlare 👋 I spend hours with music playing in a browser tab, and the tab just sits there. Silent, boring, doing nothing. So I built WaveFlare. It overlays real-time frequency bars on top of whatever you're playing. YouTube, Spotify, SoundCloud, anything. The bars react instantly to bass, mids, and highs with a glow effect that honestly makes cheap earphones feel like a concert. A few things I'm proud of: 🖤 Blackout mode: dims the whole page so it's just you and the visualizer. Great for parties or late-night focus sessions. 🎨 Four themes and three one-tap presets, plus full manual control if you like tweaking. 🔒 100% local. No audio is recorded or uploaded, no account, no tracking. I built this for myself first, so privacy was non-negotiable. ⚡ Vanilla JS, no framework, Manifest V3. It's open source (MIT) if you want to poke around. It's completely free. I'd love your feedback, especially theme ideas and what sites you'd use it on. Ask me anything about how it works, happy to nerd out about the Web Audio API and tabCapture!

The cinematic glow around the frequency bars feels really polished, like something you'd see in a music video rather than a browser extension. Love that it reacts instantly without any noticeable lag.

the glow on the frequency bars when audio peaks feels really cinematic, like it actually treats browser music as something worth watching

the frequency bars actually feel tied to the music, not just blinking randomly, and the glow gives it a nice cinematic vibe on my playlist. finally found something that makes a browser tab look intentional.
