TS-Visualizer is a web-only, local-only implementation of AST parser and visualizer. Feel free to give it a try at the official Github page.
Internally, it parses the source code entirely in browser thanks to Tree-Sitter's WASM support. It uses tree-sitter-langs's compilation of language parsers.
Any contribution will be highly welcomed. Since this is a hobby project, the code is unpolished, and support will be on best-effort basis.
