AST Explorer is an online tool that lets you paste or drop code (beginning with JavaScript) to visualize the abstract syntax tree produced by a chosen parser. It supports multiple languages and parsers and provides interactive features such as expanding nodes, highlighting the corresponding source code, and expanding subtrees. The app is built with web technologies (React, Babel, CodeMirror, Express, webpack) and offers actions like Save, Fork, and Share to manage AST views.
