Overview

Validate your HTML with a single click. For developers who need to ensure their code is compliant and clean, Validify brings the power of the W3C Nu HTML Checker directly to your browser.

Inspired by the classic "Validity" extension, this modern, lightweight tool provides a streamlined workflow for web developers and QA engineers to check for HTML issues on the fly—including on pages rendered by JavaScript frameworks.

HOW IT WORKS:
1. Click the Validify icon in your toolbar.
2. The extension sends the current page's generated HTML to the W3C validator.
3. The icon badge updates instantly with the total number of errors.
4. Open the Chrome DevTools (F12) and select the "Console" panel or the "Validify W3C Validation" panel for a detailed, interactive report of all errors and warnings.

KEY FEATURES:
• Dedicated DevTools Panel: Get a clean, organized, and filterable view of all validation issues right inside a custom DevTools panel.
• One-Click Validation: No complex setup. Just click and see the results.
• Developer Console Integration: For those who prefer the classic view, errors and warnings are also logged cleanly to the Console using console.group.
• Dynamic Content Aware: Validates the generated HTML of the page, so it works perfectly with modern JavaScript frameworks (like React, Vue, Angular) and dynamic content.
• At-a-Glance Badge: The extension icon shows the error count in red, turning green when the page is 100% valid.
• Lightweight & Fast: Built with vanilla JavaScript for minimal performance impact. No ads, no tracking, just a simple and powerful developer utility.
