What is it?

Sure is a personal finance and wealth management app that can be self-hosted with Docker. It provides a dashboard covering cashflow, net worth, and spending and outflows, and includes an AI assistant that answers questions about your finances.

The project is a community-maintained fork of Maybe Finance, which was archived in 2023. Sure can be used from a browser, a macOS desktop app, a mobile app, API clients, and LLM agents. Development requires Ruby, PostgreSQL and Redis, with setup guides for macOS, Linux and Windows, plus a demo data loader for trying the app locally.

The code is licensed under AGPLv3. The maintainers note that forks must not use the Maybe name or logo and should state that they are not affiliated with Maybe Finance Inc.

Things to know

  • Licensed under AGPL-3.0, a copyleft license that requires derivative works to be released under the same terms.
  • Local development needs PostgreSQL and Redis, plus the Ruby version listed in .ruby-version.
  • Self-hosting setup is more involved than a single install, so the README points to separate guides for it.
