Hi, I am a computer science teacher. So I need a persistent localhost tunnel / ngrok alternative for my students. So I built tunr as a ngrok alternative with vibecoding features. Then pivoted to an OSS service for vibecoded small apps.It lived on my personal GitHub for a while; I've just moved it to its own org.

I'd especially like to hear from people who show WIP to clients or grade student projects: what breaks for you in that workflow?
