Hey Product Hunt! 👋
I built Greenlight because every "mic test" site I tried either wanted me to sign up, install something, or was vague about what happened to my audio. Before a call, I just want to know: can people hear and see me?
Greenlight runs entirely in your browser using built-in audio and camera features. There's no backend that receives your audio or video, so there's nothing to upload to.
What it does:
• Live mic level meter and waveform
• Webcam preview with camera switching
• Left/right speaker test
• 10-second record & playback to hear how you actually sound
• 21 step-by-step guides for when it works here but not in Zoom, Teams, Meet, Discord, and more
It's free and ad-supported. I'd love to hear what's missing, and which apps or devices you'd like guides for next.

Who hunted Greenlight?
Greenlight was hunted by Sam Clendenin. 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.
