# Hetzner Radar
Hetzner Radar is a tool that tracks the prices of Hetzner's [Dedicated Server
Auction](https://www.hetzner.com/sb/) 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, a comprehensive pricing
history and target price alerts. Additionally, we track server volumes and other
relevant statistics.

## Features
* Track server prices and volumes over time.
* Find all configurations that match your filter criteria.
* View the lowest price seen for a specific configuration.
* *New*: Get notified when your target price is met.
## Architecture
This is a client- and backend architecture, with the website statically
built using SvelteKit. DuckDB is used in the background for querying the
database on the client.
In addition, we use Cloudflare Workers to for session management, storing
alerts and sending email notifications.
We fetch the latest auction data from Hetzner once per hour, rebuild the
database, update the website and push new configurations to the backend.
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 deployed on Cloudflare Pages.
## Development
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).
### Preparing the Database
This step is optional if you just want to work on the frontend. You can simply
download the latest snapshot from the website:
```
wget https://static.radar.iodev.org/sb.duckdb -O static/sb.duckdb
```
If you just want to inspect or play with the dataset, you can do so by running.
```
duckdb -cmd "attach 'https://static.radar.iodev.org/sb.duckdb' (read_only); use sb;"
```
Inspect the schema using the `.schema` pragma.
We use Python 3 to create a DuckDB database and ingest the auction data.
```sh
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
```
### Running the Website
To run the website, simply use the `dev` target. To build a static version, use
`build`.
```sh
npm install
npm run dev
```
