Ned can be embedded in other ImGui applications, taking advantage of its text editor, file explorer, and terminal emulator. The embedded version also includes emoji support, themes, and much more. We have a demo repository that shows how to get started embedding the neditor into your projects.
Ned is a feature-rich text editor built with Dear ImGui that combines the power of modern development tools with a lightweight, embeddable architecture. At its core, Ned provides a sophisticated text editing experience with Tree Sitter syntax highlighting supporting over 15 programming languages including C++, Python, JavaScript, Rust, Go, and more. The editor features custom lexer modes for specialized file types and includes advanced features like multi-cursor editing, line jumping, and a built-in file tree explorer.
The editor includes LSP integration with support for clangd, gopls, pyright, and TypeScript language servers, providing goto definition, find references, and symbol information. Ned also includes a terminal emulator and AI integration with OpenRouter support. The editor features emoji support with proper font rendering, custom shader effects, and a theming system. The project is designed to be embeddable in other ImGui applications through the ned_embed library, making it easy to integrate into your own projects.
Currently Ned is tested on macOS ARM and Intel, Windows x64, and has a Debian build available. Windows support includes automated dependency management through the build script.
If you have questions or issues, feel free to reach out.
Ned has an AI agent that uses OpenRouter to connect to the latest models. The agent can use MCP to call tools such as read file, run command, or edit file. The edit file tool uses a specialized model called Morph to apply code edits on large files at high speed with high accuracy, similar to Cursor. Check it out at morph.so. The whole system is tied into the settings where the key for the agent and completion model is stored. Below is a demo of the agent:

Ned has the ability to track multiple cursors at once, which can make editing in certain scenarios much easier. The multi cursor system is used for file content searches to spawn cursors at each instance of a text search string. The app also supports multi selection for selecting text with multiple cursors. The cursor also supports keybinds such as jump to line end or jump one word forward. Below is a demo:

Windows support is still being tested, but there is a windows build available in releases as well as a build script for both the standalone and embedded versions.
