Summary
Ace Template is a Rails application template that lets developers spin up a fully‑featured Rails 8+ app in under five minutes, using the standard rails new command with a -m option pointing to the template URL. The template supports interactive mode (-i) and manual option passing (-o), and includes a convenient shell alias rn for quick app creation. It offers deployment scripts for Kamal, Fly.io, and Heroku, and supports SQLite, Postgres, and MySQL databases, as well as Tailwind and Bootstrap CSS frameworks.
Key features include optional banana scaffolding, authentication with Rails or Devise, Pundit authorization, error monitoring via Rollbar or Sentry, Redis integration, VCR for HTTP test recording, and Solid Cable, Solid Cache, and Solid Queue for development. The codebase follows a commit‑per‑configuration‑step workflow, uses Rubocop, SyntaxTree, and Standard for linting and formatting, and includes RSpec tests by default with optional Minitest, FactoryBot, and Rails fixtures. The template is open‑source under MIT and is tested daily against Rails main.
Developers can customize the template with rails new options like --api, --skip‑*, --main, and --edge, and choose between single‑quote or double‑quote styles. The project also provides a modern debugging experience with IRB, ruby debug, and Amazing Print. Overall, Ace Template delivers a production‑ready Rails foundation that is both lightweight and highly configurable.
