MX Script is a lightweight scripting language designed specifically for building one-file web APIs. It addresses the complexity often associated with modern web development by offering a streamlined approach: developers can create and deploy HTTP endpoints, such as JSON APIs, in a single file without the need for frameworks, build steps, or external dependencies. The tool targets those who want to quickly ship web services or APIs with minimal setup.
The language includes first-class support for HTTP routes (GET, POST, PUT, DELETE, PATCH), path parameters, query strings, headers, and JSON bodies. Middleware composition is available using the 'use' keyword, enabling reusable request pipelines for functions like authentication, logging, and CORS. MX Script provides built-in features for sessions, signed cookies, JWT (HS256), HMAC, and SHA-256, eliminating the need for separate authentication libraries. It also supports SQL operations, file I/O, static asset serving, and background jobs. AI capabilities are integrated via built-in functions that work with any OpenAI-compatible endpoint, and the language offers WebSocket support and tool calling for AI-driven workflows. Over 200 standard library functions are included to cover common HTTP service needs.
MX Script is delivered as a single Go binary, approximately 5 MB in size, with zero runtime dependencies. gz or zip), or Go's install command. The tool can also be run directly in the browser through a live playground, requiring no installation for experimentation. Additional integration is provided through a Visual Studio Code extension for syntax highlighting and snippets, a GitHub Action for CI workflows, and first-class support for deploying to Vercel.
The project is open source, licensed under the MIT license, and developed publicly on GitHub under the repository jlkdevelop/mxscript. The language and its tooling are maintained by Jassim Alkharafi, with active development and a transparent roadmap. MX Script is positioned as a scripting language and runtime for web API development, prioritizing simplicity, portability, and a zero-dependency workflow.
In the Frameworks & SDKs space, MX Script takes a focused approach. It enables developers to quickly build and deploy lightweight web APIs without complex frameworks or dependencies. It is built as an open-source project for developers. MX Script is open source under the MIT license. The product ships for the web and the command line.
It is developed by jlkdevelop, and the product first shipped in 2026. Development happens publicly on GitHub with 223 commits in the last 90 days.
