A strictly typed, declarative document format for rich, interactive content.

RDX extends CommonMark with components, typed attributes, and structured data — without executing code. Documents are pure data: parse them into a typed AST from Rust, Node.js, Python, or the browser.

• No runtime, no execution — Components describe what to render, never how. No import, no eval(), no JavaScript in your documents.
• Runs anywhere — One parser, every platform. Native bindings for Rust, Node.js, and Python. WebAssembly for browsers and edge runtimes.
• Schema validation — Define what components exist, what props they accept, and catch errors at build time — not in production.
• Formally specified — The specification defines every construct and its AST output. Predictable, deterministic, no implementation-defined behavior.
• AI-ready — Clean text extraction for RAG pipelines, embeddings, and search indexing. No JSX artifacts polluting your vectors.
