Building a Hetzner Auction Monitor with Cloudflare and Telegram

Cloudflare + telegram is rapidly becoming one of my favourite methods for building / deploying little tools.

I built "Mike Bot" using this before, and then I've just deployed another bot that monitors Hetzner auctions. It can be a cheaper way of picking up quality servers at a severely reduced price.

So I wanted the ability to give it some parameters, and it filter the list of servers to that. I don't need a 1024GB RAM Beast for €458 p/m. So it filters all of those out, and helps me find just the kind of servers that I'm interested in.

And that's it, it runs a few times a day, and just pings me when it's found something matching my use case.

Not bad for about 5 prompts in Claude Code.
