Pinggy
Free plan ($0, free for life): HTTP(S), TCP, UDP and TLS tunnels with unlimited data transfer.
Dev Tools
What you get
Public URLs for localhost from a single command, with request inspection and replay.
How to get it
Run the ssh command shown on pinggy.io; no download needed.
The catch
Free tunnels time out after 60 minutes and get random subdomains; persistent URLs and custom domains need Pro.
