I have been working on a little price tracker for the Hetzner Dedicated Server auction (https://radar.iodev.org/). Using Sveltekit for the first time, and decided to go frontend only with duckdb-wasm.

I pull the data every hour with a GitHub action and redeploy the site nightly. The duckdb is regenerated every time and I can flexibly change its structure as required. So far I didn’t change much (eg. no normalization) since it’s not really needed. It also turns out to be surprisingly small, with compression a few megabytes. I haven’t written much SQL in some time and duckdb is very powerful.

Most of the texts are AI generated as I’m usually very bad coming up with this. I really gotta learn that one day. Webdesign is the other weakness, but with all these UI libraries these days it’s less of a problem.

I guess it’s pretty niche, but maybe interesting for some.

It’s a fun little project.



That is interesting!

Overall I find it a pretty cool tool - though I don't quite understand the red/green lines on the chart (is there a legend?).


No, I haven't figured it out yet with D3 :D

Green line: minimal price, red line, highest price (for the selected criteria). Middle one is the mean.
