Hetzner Radar is a tool that tracks the prices of Hetzner's Dedicated Server Auction over time, helping customers identify the best configurations and prices. While Hetzner's auction site allows filtering by certain criteria, it only provides a snapshot at a given moment. Hetzner Radar aims to enhance this by offering advanced filtering and a comprehensive pricing history. Additionally, we track server volumes and other relevant statistics.

• Track server prices and volumes over time.
• Find all configurations that match your filters.
• View the lowest price seen for a specific configuration.
• Utilize advanced filters such as location, datacenter, CPU, RAM, and drive configuration.

This is a single-tier, client-only architecture, with the website statically built using SvelteKit. DuckDB is used in the background for querying the database.

We fetch the latest auction data from Hetzner once per hour, rebuild the database and update the website. The raw data is stored in the data branch, where we currently maintain three months of history. We may consider purging older data if the branch becomes too large.

The project is currently deployed on GitHub Pages.

To set up your development environment, you'll need Python 3 for data ingestion and Node.js to run or build the website.

You can also use the provided Nix Flake to set up your environment (though it is somewhat neglected at the moment).

We use Python 3 to create a DuckDB database and ingest the auction data.

poetry shell
# Add the `data` branch under /data
git worktree add data data
# Build the DuckDB database
python scripts/import.py data static/sb.duckdb.wasm

To run the website, simply use the dev target. To build a static version, use build.

npm install
npm run dev
