## What it is
Bridgetown is a next-generation progressive site generator and fullstack framework powered by Ruby, built on Ruby, Roda, and esbuild. It renders Markdown, ERB, and other templates into static sites deployable to CDNs, while optionally adding dynamic server-rendered routes via Roda for fullstack applications.

## Use cases
- build a static blog or documentation site in Ruby
- generate a marketing site deployable to a CDN
- add server-rendered dynamic routes to a static site
- pull content from a headless CMS or external API and render pages
- build a fullstack web application with Ruby and Roda
- migrate from Jekyll to a more modern Ruby site generator

## When to choose
- you prefer Ruby over JavaScript for site generation and templating
- you want static site generation with an optional path to SSR/fullstack features
- you want esbuild-based frontend asset compilation out of the box
- you want an HTML-first, convention-over-configuration workflow

## When to avoid
- your team is JavaScript-only and prefers Next.js/Astro-style tooling
- you need a massive plugin ecosystem like Jekyll or Hugo's
- you need maximum build speed for very large sites (Hugo is faster)
- you want a purely dynamic application framework without static generation
