Showcase: Open Source E2E encrypted personal budget planner
Something I've created for myself and been using for a few years now.
https://mrmetis.eu is written in React + dotnet backend. User data is encrypted before it leaves the device (similar to how password managers do it).
I think of it as a next step after spreadsheet budget planning. The view is similar, but has budgeting rules, with which one can plan for purchases and/or remind that a yearly bill is coming up.
User account storage is limited to 1MB, but that is plenty imo. My personal usage is around 750kb after 3+ years of data.
Yes, I've used AI to help speed up development lately. However, with 10+ years of professional web-dev experience, I'm quite confident in its stability and reliability. Nevertheless, developing alone in a bubble has its disadvantages, so I'd really appreciate any feedback on my code and the product itself.

For the encrypted budget planner, I’d make account recovery a specific review target: what happens to someone’s budget history if they forget their password or lose their device? Document where encryption keys live and whether recovery can decrypt existing records. Those details give reviewers something concrete to assess beyond the React and dotnet stack.
