  • Easy to Embed
    Lua is designed to be embedded within applications. It has a simple C API which allows it to be integrated easily with C, C++ and other languages.
  • Small Footprint
    Lua is lightweight, with a small memory footprint. This makes it ideal for use in resource-constrained environments, such as embedded systems and game development.
  • Fast Performance
    Lua is known for its high performance due to its efficient interpreter and just-in-time compilation capabilities provided by LuaJIT.
  • Simplicity
    The syntax of Lua is simple and clean, making it easy to learn and use. It's designed to be both powerful and simple.
  • Extensibility
    Lua can be extended through libraries written in C or other languages, allowing for a lot of flexibility and functionality expansion.
  • Dynamic Typing
    Lua uses dynamic typing, which can make code more flexible and easier to write without the need for explicit type definitions.

Possible disadvantages

  • Limited Standard Library
    The standard library in Lua is relatively small compared to other programming languages, which can result in the need for additional third-party libraries.
  • Niche Use Case
    Lua is not as widely adopted for general-purpose programming compared to other languages such as Python or JavaScript, which might limit community support and resources.
  • Error Handling
    Lua's error handling mechanisms are somewhat rudimentary compared to languages that offer advanced exception handling like Python or Java.
  • Lack of Type Safety
    While dynamic typing offers flexibility, it also introduces the risk of type errors at runtime, as type mismatches can only be discovered during execution.
  • Concurrency Limitations
    Lua does not have inherent support for multithreading or concurrency within the language itself. It relies on external libraries or specific environments to handle such tasks.

Questions & Answers

As answered by people managing WCAGCheck.app and Lua.

What makes your product unique?

WCAGCheck.app's answer

Most accessibility tools require a live URL, a browser extension install, or a CI pipeline setup. WCAG Accessibility Checker works with a paste — you can check any HTML snippet, a template, or a component in isolation before it's even deployed. It also gives plain-English fix instructions, not just error codes that require a WCAG spec lookup.

Why should a person choose your product over its competitors?

WCAGCheck.app's answer

WAVE and Lighthouse require a live URL. axe requires a browser extension or test runner integration. WCAG Accessibility Checker requires nothing — paste HTML, click run, get results. It's the fastest way to do a spot check during development or review. Zero friction means developers actually use it.

How would you describe the primary audience of your product?

WCAGCheck.app's answer

Frontend developers and UI/UX designers who need to verify accessibility compliance without setting up a full audit pipeline. Also useful for accessibility auditors doing manual reviews of client code, and product managers verifying components before launch.

What's the story behind your product?

WCAGCheck.app's answer

Accessibility audits are expensive — a professional audit can cost hundreds or thousands of dollars. A lot of that cost covers things a script can catch in milliseconds. I built this so developers can fix the obvious issues before they ever reach an auditor, making both the developer's and auditor's job easier.

Which are the primary technologies used for building your product?

WCAGCheck.app's answer

HTML5, vanilla JavaScript, CSS3. Accessibility rules are implemented as pure JavaScript functions that parse and traverse the DOM representation of the pasted HTML. No external APIs, no backend, no dependencies.

Who are some of the biggest customers of your product?

WCAGCheck.app's answer

WCAG Accessibility Checker is a free tool used by individual developers, designers, and accessibility auditors. It has no paid tiers or enterprise customers.
