Declarative Tools for WebAssembly Interface Types

We've created declarative validation tools for WIT (WebAssembly Interface Type) files and Wrangler TOML configurations, enabling LLMs to validate these files with ease, reducing errors in generated code.

Our Declarative Tools

WIT Validator

Validate WebAssembly Interface Type (WIT) files to ensure they follow the correct syntax and conventions.

Perfect for AI code generation that needs to verify WIT file correctness.

Wrangler TOML Validator

Ensure your Cloudflare Wrangler configuration files are correctly structured for deploying WebAssembly modules.

Prevent deployment errors before they happen.

More Coming Soon

We're continuously developing new declarative validation tools to support the WebAssembly ecosystem.

Stay tuned for more validators and helpers coming soon!

Why WIT Is the Future of Coding

WebAssembly Interface Type (WIT) is a powerful interface definition language designed to solve one of WebAssembly's biggest challenges: interoperability between languages and environments.

WIT enables developers to define clear, language-agnostic APIs that can be seamlessly used across different programming languages and environments. This allows for true code reuse and portability:

interface example {
    record person {
        name: string,
        age: u32,
    }

    process-person: func(p: person) -> string
}

With WIT, you can:

As the Component Model and WIT continue to mature, they're becoming the foundation for a new era of cross-language, cross-platform software development.
