Show HN: ssrfproxy.com – Server Side Request Forgery Protection

I often need to make a HTTP request to a user supplied URL, but I then need to protect myself from SSRF attacks, such as users supplying URL's to "localhost:3000/protected-thing" etc. SSRF Proxy is hopefully the simplest and quickest way to get protection. Currently there is just a Node SDK but I will generate other languages soon.

It is built on Elixir/Phoenix with live view and uses https://github.com/stripe/smokescreen and nextdns in the background.
