## What it is
Down is a Ruby library for streaming, flexible, and safe downloading of remote files, with pluggable backends (Net::HTTP, http.rb, HTTPX). It downloads to Tempfiles with metadata extraction, size limits, and streaming support.

## Use cases
- download remote files to a tempfile in ruby
- stream large files over http without loading into memory
- limit download size when accepting user-supplied urls
- download files with progress callbacks
- fetch remote file metadata like content type and filename

## When to choose
- you need safe, size-limited downloads of remote files in Ruby
- you want streaming access to remote file content
- you're building file upload handling (e.g. with Shrine)

## When to avoid
- you need a full-featured HTTP client for general API requests
- you're not working in Ruby

## Facets
- artifact type: library
- maturity: stable
- function: http-client, file-upload, streaming
- domain: web-development, files, developer-tools
- platform: ruby
- tags: downloading, tempfile, partial-responses, remote-files
