[!IMPORTANT] This repository is a community fork of the now-abandoned Maybe Finance project.
Learn more in their final release doc.
The Maybe Finance (archived/abandoned repo) team spent most of 2021–2022 building a full-featured personal finance and wealth management app. It even included an “Ask an Advisor” feature that connected users with a real CFP/CFA — all included with your subscription.
The business end of things didn't work out, and so they stopped developing the app in mid-2023.
After spending nearly $1 million on development (employees, contractors, data providers, infra, etc.), the team open-sourced the app. Their goal was to let users self-host it for free — and eventually launch a hosted version for a small fee.
They actually did launch that hosted version … briefly.
That also didn’t work out — at least not as a sustainable B2C business — so now here we are: hosting a community-maintained fork to keep the codebase alive and see where this can go next.
Join us!
Sure is a fully working personal finance app that can be self hosted with Docker. Sure can be accessed from a browser, the macOS desktop app, the mobile app, API clients, and LLM agents. See Sure Clients for an overview.
This repo is a community fork of the archived Maybe Finance repo. You’re free to fork it under the AGPLv3 license — but we’d love it if you stuck around and contributed here instead.
To stay compliant and avoid trademark issues:
With data-heavy apps, inevitably, there are performance issues. We've set up a public dashboard showing the problematic requests seen on the demo site, along with the stacktraces to help debug them.

Any contributions that help improve performance are very much welcome.
If you are trying to self-host the app, read this guide to get started.
The instructions below are for developers to get started with contributing to the app.
