Hey Product Hunt! 👋 I built MicCheck Online because I kept scrambling before video calls — is my mic working? Is my webcam on? Is there a dead pixel on my new monitor? Every tool I found either required a download, had ads everywhere, or only did one thing. So I built a clean, free, browser-based toolkit: Mic test with real-time audio levels and clipping detection Webcam test with resolution and FPS readout Speaker/headphone test with frequency presets and L/R channel isolation Screen tests — dead pixel, white/black/color screens, backlight bleed, uniformity Keyboard and mouse test No login. No download. Works on any browser. Would love your feedback — what tools are missing? What should I build next? 🔗 miccheckonline.com
