Cosmic IDE is a next-generation Integrated Development Environment (IDE) for JVM development on Android, targeting developers who wish to build high-quality applications entirely on their mobile devices. It aims to provide a comprehensive and efficient development experience without requiring a separate computer.

How It Works

Cosmic IDE leverages a high-performance code editor (Sora Editor) and supports modern JVM languages like Java 17 and Kotlin 2.1 with the K2 compiler. Its architecture emphasizes extensibility through a plugin system, allowing developers to add custom functionality. Key features include Git integration, fast incremental compilation, dependency management, AI-powered code completion (via Google Gemini), and a highly customizable UI with Material You design principles.
