I've been tracking my finances for years but always found existing tools either too heavy (with features I don't need) or too simplistic. So I built Finbley – a lightweight webapp that focuses on the essentials: seeing where money comes from and where it goes.

Try it here: https://www.finbley.com

What Finbley does:

– Tracks daily/weekly spending in a clean interface

– Automatically categorizes expenses

– Shows daily, weekly & monthly summaries (biggest spend, patterns, small leaks)

– Sends accountability nudges when closer to budgets

– Helps users understand how small expenses add up

Tech Stack:

– Backend: Flask (SQLAlchemy, JWT, background jobs)

– Frontend: Bootstrap (I prefer this over Tailwind for rapid iteration)

– Database: MySQL

– Infra: Deployed on PythonAnywhere

– Future: Shared accounts, bank statement uploads, LLMs for spending summaries

I'd appreciate feedback on:

– Does it feel truly "lightweight" to you?

– What's the first thing you'd want to add?

– Any friction in transaction categorization?

– Anything that feels unclear or unnecessary?

Built this to scratch my own itch – curious if it helps others too. I’d love feedback from the HN community, especially around UX, onboarding, and technical architecture.

Thanks!
