Exactly, since KasmVNC can run GUI programs in the browser and the Linux server.io base image is just Debian, it was trivial to just run it with Emacs instead. I much prefer Emacs over VS Code because of Org Mode. While VS Code works well in a browser. It isn’t what I wanted.

Here is where I have posted my Emacs Dockerfile. It might be a little out of date. Emacs Docker

EDIT: The Dockerfile also installs the fonts I like for Emacs along with git and hunspell.

EDIT: You could also probably achieve something similar with a Docker container run ning Apache Guacamole.

You can use the Linuxserver.io VSCodium Image and replace VSCodium with Emacs in the Dockerfile.

Firefly III is an option, but I found it difficult to set up and the importer tool works well for Europe but not the US.

You could also just create your own Docker container which has Skrooge, GnuCash, or KMyMoney in it. I have done this with Skrooge since it imports data well and is simpler than GnuCash.

With the Linuxserver.io KasmVNC base image and install any GUI application to run it from a browser.
