Sure: The personal finance app for everyone

Get involved: Discord • Website • Issues

[!IMPORTANT] This repository is a community fork of the now-abandoned Maybe Finance project.
Learn more in their final release doc.

Backstory

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!

Hosting Sure

Performance 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.

One-click Install

Render expects each button target branch to have a render.yaml at the repository root. The branch-ready Blueprint files live in branches/<branch-name>/render.yaml in a separate repo and can be copied to each corresponding branch root.

Option	What it deploys	latest	stable
Sure - No AI	Sure web, Sidekiq worker, Render Postgres, and Render Key Value. AI tokens are intentionally blank.
Sure - Simple AI	Sure with OpenAI-backed AI settings, pgvector-ready Postgres, Sidekiq, and Render Key Value. Render prompts for the OpenAI token.
Sure - External AI	Sure with external assistant settings plus AlphaClaw, which manages the OpenClaw gateway on Render.
