Ideon

IDEOn is a cross-platform integrated development environment (IDE) designed to support software development in multiple languages and paradigms. It runs on Windows, macOS, and Linux and provides a unified interface for editing, building, debugging, and deploying applications. IDEOn targets individual developers as well as teams, offering project templates, version control integration, and a customizable workspace.

Its features include a code editor with syntax highlighting and intelligent code completion, an integrated debugger with breakpoints and variable inspection, built-in test runners and profilers, and support for multiple language runtimes. IDEOn supports a plugin system and a marketplace for extensions, enabling language servers, linters, formatters, and deployment tools. It also supports remote development workflows and container builds via Docker integration.

IDEOn was released in 2019 by NebulaSoft. The product is built on a modular architecture with separate components for the editor, language tooling, and user interface. It offers a free community edition and a paid professional edition that adds enterprise features such as team collaboration, advanced code analysis, and priority support.

Reception has highlighted its extensibility and cross-language approach as major strengths, while some reviewers note performance variability on very large codebases and point to a learning curve associated with its configuration options and workflow.
