What Middleman is

Middleman is a free, open-source static site generator and framework for building websites. It uses Markdown and other source files, then compiles templates and copies static files into a production-ready build. RubyGems distributes Middleman, and installation requires Ruby and RubyGems. Its command-line tools include `middleman init`, `middleman server`, and `middleman build`; the server provides local preview. Included template engines cover ERB, Haml, Sass, SCSS, and CoffeeScript, with more available through Tilt-enabled gems. Settings and extension configuration go in `config.rb`, while Ruby extensions can add features and expose methods to templates. The i18n extension builds localized pages from locale YAML files and templates. An external pipeline can run subprocesses such as Ember, webpack, or Broccoli. `middleman-deploy` supports rsync, FTP, SFTP, and Git. Community resources include extensions, project templates, deployment options, and a forum. Paid consultation is also offered.

Who it suits

Middleman suits developers building static sites with Ruby-based tooling, configurable templates, localization, and scripted deployment. It is intended for generating static sites rather than hosting an app in Rack development mode.

What it does well

Free and open-source
Includes local preview server
Supports multiple template engines
Builds localized pages with i18n
Deployment supports rsync, FTP, SFTP, and Git

What to know first

Requires Ruby and RubyGems
Rack development hosting is not a primary use case
Rails Asset Pipeline was removed from v4 core
Future of Rails Asset Pipeline support is uncertain

Limits

The Rails Asset Pipeline is no longer part of Middleman v4 core, and its future depends on community maintainers. Hosting in Rack development mode is not a primary intended use.

Getting started

Install Ruby and RubyGems
Install Middleman through RubyGems
Create a project with `middleman init`
Configure settings and extensions in `config.rb`
Run `middleman server` for a local preview
Run `middleman build` to generate production files

Verdict

Middleman provides a Ruby-based workflow for creating static sites, with extensible templates, localization, build commands, and deployment tooling. Its main limitation is that it is a generator rather than a primary Rack hosting solution, and the Rails Asset Pipeline is no longer in v4 core.
