Yesod is a type-safe, RESTful web framework for Haskell built on the WAI interface, featuring compile-time-checked routing, templating, and persistence DSLs. It emphasizes turning runtime bugs into compile-time errors while delivering high performance through compiled code and asynchronous IO.

Use cases

• build a type-safe RESTful web API in Haskell
• develop a high-performance web application with compile-time route checking
• create a web app with safe HTML templating and form handling
• build a database-backed website with compile-time-checked persistence
• serve a web application with constant-memory, asynchronous IO

When to choose

• you want maximum type safety and compile-time guarantees in web development
• you need high performance compiled web applications in Haskell
• you value DSLs for routing, templating, and persistence that are checked at compile time

When to avoid

• your team does not know Haskell or wants a shallow learning curve
• you need a large ecosystem of off-the-shelf plugins and libraries
• you prefer dynamic or scripting languages for rapid prototyping
