What won me over is how little friction there is between needing a public URL and having one — one SSH command, no account setup, no client to install. That simplicity held up across a Node project, a Django app, and a mobile build needing HTTPS callbacks, with zero adjustments needed. Under real use — long debugging sessions, sustained webhook traffic from Stripe and GitHub — tunnels come up in seconds and stay up thanks to auto-reconnect. It's an easy sell cost-wise too: the free tier covers most day-to-day testing, and the paid tier costs far less than the time I used to lose deploying to staging just to test something small. I've never had to reach out for support either — the docs answered everything.
