Hi, I’m exploring how to create a proxy service. My use case is this: I have a Next.js + Puppeteer application on Vercel, which works fine but I’d like to have static outbound IPs so my clients can add them to their allowlists. I could sign up for a Fixie account, but it could be a bit pricey due to the high volume of requests.

As Render offers static outbound IPs, I’d like to explore creating a simple proxy service (ideally using Elixir) that I could host in Render. It’s something like having my own Fixie service.

Has anyone experience in this field? What are your recommendations? A forward, transparent HTTPS proxy is enough, but SOCKS support would be better.
