One of the original popular use cases for services like this was if you're developing against a third-party service that wants to send you webhooks.

But it's also useful if you want to run something locally and show it to a friend or co-worker. The co-worker bit is especially useful now with people working from home.

Regardless, this space is pretty crowded, so I'm not sure what a new offering could do to differentiate. I'm skeptical of their "6x faster than ngrok" claim, and even if it is true, I don't think this is a use case where that metric really matters all that much.

(Full disclosure: the founder of ngrok is a friend of mine, so I'm certainly biased here.)
