What it is

Sure is a community-maintained fork of the abandoned Maybe Finance app. It provides a full personal finance and wealth-management web application: a dashboard for cashflow, net worth, spending and outflows, plus an AI assistant that can answer questions about your finances. The app is accessible from a browser, a macOS desktop app, a mobile app, API clients and LLM agents (Sure Clients).

It is aimed at people who want to run their own finance tracker rather than depend on a hosted service, and at Ruby developers who want to contribute to the codebase.

Quick start

Self-hosting is the intended route and uses Docker; follow the Docker hosting guide. For local development you need the Ruby version in .ruby-version, PostgreSQL > 9.3 and Redis > 5.4.

cd sure
cp .env.local.example .env.local
bin/setup
bin/dev

# Optionally, load demo data
rake demo_data:default

Then open http://localhost:3000. If demo data was loaded, sign in with user@example.com / Password1!. Platform-specific setup notes exist for Mac, Linux and Windows, and a dev-container route is also documented.

Deployment options

Besides Docker, one-click templates deploy to Render in three variants: no AI, OpenAI-backed "Simple AI", and external AI using the OpenClaw gateway. There are also buttons for PikaPods and Hostim. Check which variant matches your AI setup before choosing, since the no-AI template leaves AI tokens blank.

Constraints

• Ruby, PostgreSQL and Redis are required for local development; self-hosting is Docker-based.
• Performance can degrade with large datasets. The project publishes a public Skylight dashboard with problematic requests and stacktraces for debugging (performance dashboard).
• The code is under AGPLv3. Forks must keep the original license and state they are based on Maybe Finance without affiliation or endorsement. The name "Maybe" is a trademark and cannot be used in forks; "Sure" refers to this community fork.
• The AI features depend on an external model provider token; the no-AI deployment leaves this unset.

HotRepo's take

On 2026-11-10 Sure recorded 184 stars gained in the daily all-language ranking and reached 6th place on GitHub's overall daily list, bringing the repository to 11,373 stars and 795 forks. That is a strong single-day signal for a fork of an abandoned project, and it fits the project's positioning: a real, runnable app with self-hosting and multiple deployment paths rather than a thin wrapper. The README's own performance section is a useful, concrete caveat — the maintainers point at real slow endpoints instead of claiming the app scales cleanly.
