Why Moneygun?

Skip weeks of boilerplate. Ship your B2B SaaS faster with production-ready:

Multi-tenant architecture - Route-based organization management
Team management - Invitations, roles, member administration
Stripe subscriptions - Optional payments via Pay gem, ready to monetize when configured
Authentication - Devise + OAuth (Google, GitHub)
Authorization - Pundit policies per organization
Modern UI - Tailwind CSS, daisyUI, dark mode

Teams should be an MVP feature. Learn why

Quick Start

git clone git@github.com:yshmarov/moneygun.git my-saas
cd my-saas
bin/setup
bin/dev

Local Development Notes

Database Configuration: The config/database.yml has been updated to connect to the PostgreSQL instance running via Docker (my-postgres-db). The default block specifies host: localhost, port: 5432, and the postgres user credentials.
Stripe: Stripe support is included through Pay, but the local Stripe webhook listener is not started by Procfile.dev by default. Run it separately when configuring payments so bin/dev does not crash if the Stripe CLI is not installed or logged in.

Deploy

Deploy to production with Kamal. See the Deployment Guide for details.
