The following site works for The Netherlands (not just Amsterdam): https://mapitout.iamsterdam.com/

It has some minor limitations to select the time (has to one of the predefined options). That can be worked around by changing the URL parameter.

It can also map out multiple locations and see the overlap.

It's fairly useful to see where you want to live while taking e.g. the office location into account. It gave me more options than I thought I had, partly because I didn't think about small towns with a train station.

Wow, this website is very pretty. It's similar to what I envisioned when I built this project, but I wanted to make a heatmap (of all possible times) rather than just an isochrone. The little "islands" of fast transit access is also what I wanted to show with my project too! It's cool to discover the little spots near train stations that are cheaper but offer an equivalent commute to the city center.

There's also https://www.chronotrains.com which was another inspiration when building this project too.

Hey, that's super interesting. Put in my and my SO's current distances, and the overlap seems pretty accurate (though smaller than I was hoping for!)
