Wormhole

Judgement

What it is

Developer tool

What it does

An ngrok-style tunnel that gives a local server a public HTTPS URL with one command, with custom subdomains after GitHub sign-in, a local traffic inspector, request replay and HAR export. The client is written in Go and the relay runs on Cloudflare Workers.

Adopt it when

You need to share a dev server or test incoming webhooks and are happy to rely on the maintainer's hosted relay or deploy your own.

Watch out

It is at version 0.3 from a single author and routes your traffic through a relay you do not control unless you deploy your own.

Ready for
