Sure is a personal finance app that users can self-host or access through a browser, desktop application, or mobile client.
The tool addresses the need for accessible personal finance management by providing a fully-featured wealth management platform that was originally developed as a commercial product. It includes capabilities for tracking finances and can be accessed through multiple client types including browser, macOS desktop, mobile apps, API clients, and LLM agents. The application is built in Ruby and can be deployed using Docker for self-hosting.
Developers considering adoption should know that Sure is a community-maintained fork of the abandoned Maybe Finance project, which spent substantial resources on development before the original team open-sourced the codebase. The tool suits anyone seeking a self-hosted personal finance solution or those interested in contributing to an open-source financial application. Anyone forking the project must include proper attribution to Maybe Finance and clearly state that their fork is not affiliated with or endorsed by the original company.
The project maintains a public performance dashboard tracking problematic requests and stack traces from the demo site, actively soliciting contributions that improve performance. Development activity centers on addressing data-heavy application challenges, with the team documenting known performance issues and inviting the community to help resolve them.
