Clack is a web application environment for Common Lisp that provides a server abstraction layer inspired by Python's WSGI and Ruby's Rack. It lets applications run on interchangeable backends like Hunchentoot, Woo, Wookie, and Toot, and includes a clackup CLI for deployment.

Use cases

• build a web app in Common Lisp
• run a Common Lisp web server behind a portable abstraction
• swap web server backends without changing app code
• deploy a Lisp web app with a command-line launcher
• write middleware-based Lisp web applications with Lack
• serve a simple HTTP endpoint from a Lisp lambda

When to choose

• you're writing a Common Lisp web application and want server portability
• you want a Rack/WSGI-style handler interface in Lisp
• you need a simple CLI to start and stop Lisp web servers in production

When to avoid

• you're not using Common Lisp
• you need a full-featured batteries-included web framework rather than an abstraction layer
• your stack is already tied to a single server like raw Hunchentoot
