Yesod

Yesod is a web framework for building websites and online applications using the Haskell programming language. It provides tools and structures that help developers create secure, performant, and maintainable web systems efficiently. By leveraging Haskell's strengths—such as strong type safety and functional programming principles—Yesod ensures that common errors are caught early, and the resulting applications are robust. It simplifies tasks like routing (mapping URLs to code), handling user input, and database interaction, enabling developers to focus on building features rather than low-level details. Overall, Yesod is a tool for creating reliable, scalable web services with a focus on correctness and security.
