IHP is a full-stack web framework that enables developers to rapidly build web applications with Haskell, a functional programming language with the industry-leading type-system. IHP has built-in web-based IDE to improve developer productivty. The IDE includes a database schema designer, a web-based code generator and a web-based repl. Thanks to it's strong type-system, IHP applications are a lot more robust compared to applications build with other technologies: - Null-Pointer-Exceptions (NPE's) are impossible by design, they don't ever occur at runtime - Improved security as common security issues like XSS and SQL Injection will lead to compile-time type errors - The application can be refactored safely without worrying that it breaks other parts of the system
