A simple Telegram bot that monitors Hetzner server auctions and sends notifications when it finds deals matching your criteria. Hetzner auctions can be a cheaper way of picking up quality servers at severely reduced prices.

Features

• Natural Language Filtering: Give it instructions like "I want a server that can handle video processing with at least 32GB RAM" and it filters the auction listings accordingly
• Automated Monitoring: Runs multiple times a day to check for new listings
• Smart Notifications: Only pings you when it finds servers matching your specific use case
• Serverless Architecture: Deployed on Cloudflare Workers for free, reliable hosting
• Built Fast: Created in just 5 prompts using Claude Code

Why I Built This

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

Technical Implementation

This bot is built using TypeScript and deployed on Cloudflare Workers, leveraging the Telegram Bot API for messaging functionality. The bot periodically scrapes Hetzner's server auction page and applies natural language-based filtering to match your requirements.

What I Like About It

• Zero hosting costs with Cloudflare Workers
• Natural language interface makes it easy to specify exactly what you need
• Saves time by automatically filtering out irrelevant listings
• Simple and focused on solving one problem well
