I wrote a tunneling service called Packetriot that is similar. It's probably slightly older than inlets. However, it's not an opensource project. The tunnels are assigned static hostnames and the servers you connect to are static as well, so setting up CNAME and A records for custom sites are simple. You can host any number of websites or services behind a single tunnel.
Let's Encrypt is built-in and can manage all of your certs automatically. The client can serve static assets and upstream to app servers, so you can eliminate the need for an extra web server running in your environment.
There are packages for Deb, RPM, containers, mac and windows, and for almost all architectures (x86/amd64/arm32/arm64).
I designed the service for 24/7 operation so uptimes for tunnels are weeks at a time. They auto-reconnect if there's a connection drop. You can find it here: https://packetriot.com
