tarik is an open-source SaaS boilerplate combining Rails 8 (API mode) and Next.js 16, pre-wired with JWT auth via Devise, Stripe payments, EN/JA i18n, PostgreSQL, Redis, Sidekiq, Docker, GitHub Actions CI, and Railway deployment. It targets developers who want to skip repetitive setup and start building product immediately. Key design decisions include a frontend-agnostic Bearer token auth model, service-object-based payment logic, and an AGENTS.md file to help AI coding agents navigate the codebase. It also includes a migration guide from Stripe to PAY.JP for the Japanese Ruby ecosystem.
