Obelisk is a batteries-included full-stack framework for building functional reactive web and mobile applications in Haskell using Reflex/Reflex-DOM. It provides a curated, opinionated toolchain (backed by Nix) that lets a single Haskell codebase target web, iOS, and Android with rapid development and deployment workflows.

Use cases

• build a web and mobile app from one haskell codebase
• functional reactive programming for web uis
• full-stack haskell web framework with nix
• deploy a reflex app to ec2
• share types between frontend and backend in haskell
• build ios and android apps in haskell

When to choose

• your team knows Haskell and Reflex/Reflex-DOM
• you want one codebase for web, iOS, and Android
• you want an opinionated, batteries-included stack instead of assembling tools yourself
• you value end-to-end type safety across client and server

When to avoid

• you or your team don't know Haskell
• you need a mainstream ecosystem with large hiring pools and community libraries
• you want fine-grained control over every technology choice
• you're building a simple static site or a non-reactive app
