Open Source Elixir User Interface (UI) Software

Kaffy is an Elixir/Phoenix library that provides a powerful, customizable admin interface with minimal setup. Inspired by Django’s built-in admin and Rails’ ActiveAdmin, it allows developers to manage data models, forms, dashboards, and navigation without altering their existing codebase. Kaffy auto-generates CRUD interfaces for your Ecto schemas, supports advanced customizations, and integrates seamlessly with Phoenix projects. It’s designed to be both simple for quick setup and flexible enough for complex admin needs.

Surface is a component-based UI library for Phoenix LiveView that brings a declarative, template-driven approach to building interactive interfaces. Inspired by frameworks like React, it introduces components with typed properties, slots, and macros to simplify complex UIs. Developers can create reusable, encapsulated components that integrate seamlessly with LiveView’s server-rendered real-time model. Surface emphasizes readability, making templates feel closer to HTML while retaining Elixir’s functional power. It also provides form helpers, event bindings, and a growing ecosystem of ready-to-use UI components. By combining the productivity of declarative components with LiveView’s real-time updates, Surface enables rich, interactive apps without requiring a separate frontend framework like React or Vue.
