The MDX engine for
the performance era.

Stop waiting for JavaScript to parse your content. Omni-MDX leverages a pre-compiled Rust core and the zero-copy OCP protocol to parse Markdown, JSX, and LaTeX instantly.

AST Parsing Speed

23x

Faster than standard JS.

omni-mdx (Rust)0.53 ms
Standard JS Engine~12.2 ms

Native Math & JSX

Effortlessly handles complex component trees and LaTeX formulas natively. Stop hacking standard Markdown parsers to do MDX's job.

Zero-Copy OCP

Data is transmitted from Rust to Node.js/Python via our proprietary Open Core Protocol buffer, eliminating costly JSON serialization.

Structured for AI

Built to ingest massive amounts of text instantly. Ideal for generating clean abstract syntax trees for LLM data pipelines and RAG applications.

Frequently Asked Questions

Do I need to know Rust to use Omni-MDX?
Not at all. We provide high-level, zero-cost wrappers for JavaScript/TypeScript and Python. You just import the library via npm or pip and use it like any standard parser. The Rust core runs transparently under the hood.
Is it really 23x faster than standard JS parsers?
Yes. Traditional parsers like remark or unified build their AST using heavy JavaScript objects, which causes massive memory allocation overhead and garbage collection pauses. Omni-Core parses the text in native Rust and sends it straight to your app using a highly optimized flat binary buffer (OCP).
Does it support standard Remark/Rehype plugins?
Yes ! While the core engine is written in Rust for maximum speed, Omni-MDX includes a seamless bridge to the unified ecosystem. It fully supports Rehype plugins, allowing you to use popular tools like rehype-highlight, rehype-slug, or rehype-autolink-headings to transform your content. Note that we skip the remark (Markdown AST) phase entirely because our Rust core directly generates a high-level AST for better performance. Additionally, features that usually require plugins—such as GFM Tables, KaTeX math, and JSX components—are built natively into the core, giving you maximum speed with zero configuration.
