What it does

Moneygun is a ready‑to‑run Rails 8 boilerplate that gives you SaaS‑style multitenancy (users, memberships, organizations) with row‑level scoping based on URL parameters.

When to use it

•You need to launch a new B2B SaaS product and want a full Rails app with multitenancy already wired.
•You want to avoid building the user‑organization‑membership data model and tenant switching logic from scratch.
•You prefer a row‑based (single‑database) multitenancy approach that works out‑of‑the‑box with sub‑paths like `/myco/dashboard`.

Ready-to-paste prompt

Open a new tenant in your browser: `open http://localhost:3000/acme/dashboard` (replace `acme` with the slug of an existing Organization record). This URL triggers Moneygun’s `set_current_tenant` callback and scopes all queries to the `acme` row‑level tenant.

Heads up: Moneygun expects the tenant slug to be passed as the first segment of the path; if you run the app behind a proxy or use a different routing base, you must keep the `config/initializers/multitenancy.rb` logic in sync or the app will fall back to the default (public) tenant.
