Hey all,
I am super interested in building in the open with the community on a free, self-hosted, personal finance app called Sumurai that I originally made for my small business: github.com/TwoBitFoundry/sumurai
I’ve been programming over 10 years, most for small and large businesses alike, and would love the chance to build something with others and even mentor some devs newer to the field.
It’s a completely free, bring your own api key experience that supports multiple users and accounts, via Teller which is a financial provider with their own terms of use and data usage policy you’d have to consent to. It works for personal or business accounts, however you’d like to use it. Supports approx. 7k banks in the USA.
I found a lot of different open sourced options out there, but a lot of them were paywalled or blocked features that made the app useless without a lot of manual labor. I made something simple and useful without needing an expensive monthly fee to use. I also plan on open sourcing a few other tools I made for other businesses as well.
Whether you like to collaborate with me or give some feedback, happy to meet you!
EDIT: Clarified that Teller is a financial provider, and to use the app you’d have to consent to their terms of service and data usage policy.
