I did a similar thing but with graphhopper for routing since it supports gtfs for public transit. I was just barely able to host tiles for and travelroute Sweden on a 16GB M1 MBP. It wasn’t fun though, graphhopper felt yanky and the travel time isochrones looked very jagged and not quite right. OSM style tiles were fine to host though with enough disk. Routing is the tricky part, especially public transit.

Hosting tiles with graphhopper? Do you mean the vector tiles we serve only for debugging purposes?
> the travel time isochrones looked very jagged and not quite right
For public transit? The GTFS does not give much room to interpret this. Or do you mean road vehicles?

Exactly. And this is the reason your comment is tricky to interpret as the original post was about road routing and for isochrones you meant probably also road routing but in your case you included GTFS and then the initial setup is a lot more demanding. So not really comparing apples with apples ...
I don’t remember in detail but it wasn’t obvious for me how to set it up, which version to use, it was difficult to reason about error messages, etc.
I used the docker image overv/openstreetmap-tile-server for the tiles.
The isochrones looked jagged for both public transit and road as far as i remember.
What’s tricky to interpret about my comment? I wanted to share that it’s possible to host google maps alternatives on a laptop with free software but it’s tricky to setup and not a smooth and fun experience, especially if you also want public transport routing, which is a hard problem.
