Top Pinggy Alternatives, Explained

1. Cloudflare Tunnel

Free tier4.7· Free

Cloudflare Tunnel runs a small daemon, cloudflared, that opens outbound connections to Cloudflare; traffic for your hostname comes in through Cloudflare’s network, with its CDN, WAF and Access login in front, and no inbound port is ever opened. Named tunnels are free and need a domain using Cloudflare DNS. Quick Tunnels (cloudflared tunnel --url) need no account and give a random trycloudflare.com URL, but they have no uptime guarantee, cap at 200 in-flight requests and do not support server-sent events, so they are for testing only. It lacks ngrok’s request inspector and replay.

Free with no bandwidth meter
No inbound ports, with Cloudflare security in front
Fine for long-running production services

2. ngrok

Free tier4.7· Free · paid from $10/mo

ngrok gives a local or private service a public HTTPS URL in one command, with a request inspector and replay that make it the default for testing webhooks and OAuth callbacks. It has grown into a general ingress platform: traffic policies, OAuth and IP restrictions in front of the URL, and an SDK to embed tunnels in your own app. Pricing as of October 2026: Free (3 endpoints, 1 GB transfer, 20K requests, one dev domain, and an interstitial warning page on HTTP), Hobbyist $10/month with no interstitial, and Pay-as-you-go from $20/month plus usage, which adds your own domains at $0.01 per active hour.

One command to a public URL, on every OS
Request inspector and replay for webhook debugging
Auth and traffic policy in front of the tunnel

3. zrok

Free tier4.4· Free · paid plans by quote

zrok shares a local web server, files or TCP/UDP service either publicly through a URL or privately, so only other zrok users you allow can reach it, with no URL on the internet at all. It is built on OpenZiti, NetFoundry’s open-source zero-trust overlay, and is Apache-2.0 licensed and actively maintained. The hosted service at zrok.io is free with 5 GB of bandwidth a day, 25 environments and 50 shares; commercial plans are by quote from NetFoundry. Self-hosting removes every limit, at the cost of running an OpenZiti network.

Apache-2.0 and self-hostable with no limits
Private shares with no public URL at all
Generous free hosted tier
