SoundTest
SoundTest is a suite of free, in-browser audio tools. Test your left and right speakers and headphones, run a frequency sweep, generate any tone or DTMF dial tones, detect the musical note from your microphone, and measure ambient sound level in decibels. Everything runs client-side with the Web Audio API, nothing is uploaded, and there is no sign-up.

The part that stood out was keeping everything client-side rather than treating privacy as an afterthought.
For utility tools like this, removing sign-ups and uploads lowers the friction enough that people can verify the tool works before they have to decide whether to trust it.
