24 alternatives to lambda-nat-proxy – Serverless proxy using Lambda and UDP NAT punching

Revisited an old experiment of mine (https://github.com/dan-v/awslambdaproxy): can AWS Lambda functions work as network proxies? This time using UDP NAT hole punching + QUIC tunnels. Client discovers public IP via STUN, writes session data to S3, which triggers a Lambda. Both endpoints punch UDP holes through their NATs, then establish a QUIC connection for encrypted traffic forwarding.

Lambda-nat-proxy is a serverless network proxy built on AWS Lambda that uses UDP NAT hole punching and QUIC tunnels to forward encrypted traffic. A client discovers its public IP via STUN, writes session data to S3 to… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

    Pipenet – A Modern Alternative to Localtunnel▲114

    Hey HN! localtunnel's server needs random ports per client. That doesn't work on Fly.io or behind strict firewalls. We rewrote it in TypeScript and added multiplexing over a single port. Open-source and 100% self-hostable. Public instance at *.pipenet.dev if you don't want to self-host. Built at Glama for our MCP Inspector, but it's a generic tunnel with no ties to our infra. https://github.com/punkpeye/pipenet

    Test your WireGuard connectivity and see global stats, no client needed▲43

    Hi HN, Some misbehaving networks drop WireGuard packets either by accident or on purpose. Commonly the latter is done with simple DPI rules that block the handshake initiation [1], but it could be applied to other message types as well. We thought it would be great if there was tool for folks to use as a quick litmus test to see if this happening for them, without having to configure a client to send data through a random, functional WireGuard tunnel to an untrusted remote host. So we built probe.sh. How it works: - The probe.sh web app is an Elixir Phoenix app that spawns a few gen_udp…
