 * [ngrok 2.0](https://ngrok.com/) - Probably the gold standard and most popular. Closed source. Lots of features, including TLS and TCP tunnels. Doesn't require root to run client.
 * [CloudFlare Tunnel](https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/install-and-setup) - Excellent free option. Nicely integrates tunneling with the rest of Cloudflare's products, which include DNS and auto HTTPS. Client [source code](https://github.com/cloudflare/cloudflared) is Apache 2.0 licensed and written in Golang.
+* [Pinggy](https://pinggy.io/) - SSH based single command HTTPS / TCP / TLS tunnels, no downloads required. Rich terminal interface and a web debugger. Free tier - 60 min timeout. Paid tier allows custom domains with built-in Let's Encrypt certificates.
 * [Loophole](https://loophole.cloud/) - Offers end-to-end TLS encryption with the client automatically getting certs from Let's Encrypt. QR codes for URL sharing. Client is open source. Can serve a local directory over WebDAV. MIT License. Written in Go.
 * [localhost.run](https://localhost.run/) - Simple hosted SSH option. Supports custom domains for a cost.
 * [Packetriot](https://packetriot.com) - Comprehensive alternative to ngrok.  HTTP Inspector, Let's Encrypt integration, doesn't require root and Linux repos for apt, yum and dnf.  Enterprise licenses and self-hosted option.
