A demo of the Web UI can be found at https://demo.paisa.fyi
I use it to track my personal finance. It's more like alpha product now, usable, but I might update things based on the feedback I receive. Feel free to open an issue if you found a bug or start a discussion if you have a feature request. If you have any question, you can ask on Matrix chat.

Paisa is open source, but I do not plan to accept any pull request for now. If you have a feature request, start a discussion, or if you found a bug, create a new issue. Since this a UI project, I would prefer to have full control over how things are done. I might relax this restriction later.
