## What it is
Simple Form is a Ruby gem that provides a flexible DSL for building forms in Rails applications without imposing markup opinions. It wraps Rails form helpers with powerful components, customizable wrappers, and integrations for Bootstrap and Foundation.

## Use cases
- build forms in rails with less boilerplate
- generate form markup matching bootstrap styling
- create custom form inputs for active record models
- customize form wrapper html around inputs
- handle collections and associations in rails forms
- build forms for non-active-record objects

## When to choose
- you're on rails and want a mature, battle-tested form builder
- you need flexible markup control with a concise DSL
- you want easy bootstrap or foundation form integration

## When to avoid
- you're not using ruby on rails
- you prefer building forms with frontend frameworks like react or vue
- you want fully automatic styling with zero configuration

## Facets
- artifact type: library
- maturity: stable
- function: form-handling, templating, ui-components
- domain: web-development, frontend, backend
- platform: ruby
- tags: rails, form-builder, dsl, bootstrap, active-record, web-server
