Alpha: The plugin is under active development. Some features may not work correctly.
NetBeans Claude Code GUI is a NetBeans IDE plugin that embeds the Claude Code CLI as a full interactive terminal session directly inside the IDE. You type prompts in a dedicated session tab, Claude reads and edits your project files, and the plugin provides:
- a graphical file diff (using NetBeans' built-in diff viewer) before any change is written to disk
- a graphical panel for responding to Claude's interactive questions
IDE integration (open editors, diagnostics, current selection) is exposed to Claude via the MCP protocol so that Claude always has full context about your work.
The plugin code was written entirely by Claude Code using Claude Sonnet 4.6, with the author acting as architect and reviewer.
