sure: Personal finance app with $1 million in development costs is now open source

Sure is an open-source solution that revives the discontinued personal finance management app, serving as a community fork of the Maybe Finance project. This app, which took approximately $1 million in development costs to complete between 2021 and 2022, includes an 'Ask an Advisor' feature that connects users with financial advisors holding CFP/CFA credentials.

It supports self-hosting via Docker and offers various interfaces, including a browser web app, macOS desktop, mobile app, API client, and LLM agent. It is built on the Ruby and JavaScript ecosystems and uses PostgreSQL and Redis.

With the original Maybe Finance ceasing development and archiving the project due to business failure, the goal is for the community to lead the maintenance and evolution of the codebase. It can be freely forked under the AGPLv3 license, but the use of the 'Maybe' trademark is prohibited.

It is suitable for developers who prefer data-driven financial management or individual users who prioritize privacy on their own infrastructure. Contributions for performance optimization are welcome, and issue requests can be tracked and debugged on the public dashboard.
