## What it is
Formtastic is a Rails FormBuilder DSL plugin for generating semantic, accessible, and easily stylable HTML forms. It provides a concise input/action API on top of Rails form helpers.

## Use cases
- generate accessible Rails forms with semantic HTML
- build forms from ActiveRecord models with minimal markup
- add labels, hints, and error messages to form inputs automatically
- create nested forms for associated models
- style forms consistently with fieldsets and lists

## When to choose
- you're on Rails and want DRY, semantic, accessible form markup
- you want automatic labels, hints, and error handling for model-backed forms
- you prefer a DSL over hand-writing form HTML

## When to avoid
- you're not using Rails or an ActiveModel-compatible ORM
- you need highly custom non-model-driven form layouts
- you're on Rails below 6.0 (or below 7.2 for the latest version)

## Facets
- artifact type: library
- maturity: stable
- function: form-handling, templating, ui-components
- domain: web-development, backend, accessibility
- platform: ruby
- tags: rails, form-builder, dsl, html-forms, semantic-markup, web-server
