Waltzing

AI Templating Agent for Rust

Transform .wtz template files into type-safe Rust code. React-like components with MCP-powered AI development.

Features

Composable Components

Templates compile to callable Rust functions (buffered or streamed). Function tags provide JSX-like syntax. Default parameters make components flexible. Compose UIs like React but with compile-time safety.

AI-Powered Development

MCP server for Claude and other AI assistants. LLM agents understand Waltzing syntax and generate templates automatically.

Type-Safe

Templates compile to Rust code at build time. Type errors are caught by the compiler.

Editor Integration

LSP server for autocompletion and diagnostics. Tree-sitter grammar for syntax highlighting. Extensions for Zed and VSCode.

Htmx & Alpine.js

Plays nicely with Htmx, Alpine.js, and similar technologies. Embedded JSON blocks for Alpine x-data attributes.

Streaming

Both buffered and streaming render modes. Stream HTML chunks for faster time-to-first-byte.

Embedded Languages

First-class support for JSON, JavaScript, and CSS blocks with template interpolation.

AI-Assisted Development

Waltzing is designed for AI-first development. Use the MCP server with Claude Code or other AI assistants to generate and modify templates automatically.
