windirstat with web based gui?
(lemmy.one)
I've used this before: https://hub.docker.com/r/linuxserver/qdirstat
IIRC it uses a lot of RAM while running though so double check that.
I guess you could run guacamole for this? It would be a full rdp session then. https://guacamole.apache.org/
Give ncdu a look. It is on Linux. It will allow you to see big chunks of data. I'm sure someone has a container version of it, but you can run it straight from the terminal.
If it's free and open source and it's also software, it can be discussed here. Subcommunity of Technology.
