Web & Sites

This universe brings together twenty-two free tools for creating, checking, and improving a site. It covers five subcategories: Tags & Metadata, Markdown & HTML, Web Diagnostics, Page Utilities, and Web Performance. You will find tools such as Meta Tag Generator to prepare a page, Markdown preview to write safely, and Page weight to add up assets. They require no sign-up and run in the browser.

To choose, start from the subcategory that matches your task. Tags & Metadata covers metadata and social sharing preparation. Markdown & HTML helps convert and preview content. Web Diagnostics inspects thresholds, headers, and redirects. Page Utilities adds campaign parameters, protects expressions, or obfuscates an address. Web Performance groups weight, budget, responsive images, critical CSS, preload hints, and speed. Begin with the closest subcategory, then open the matching tool.

How to use

  1. Start from the subcategory closest to your task: Tags & Metadata to prepare a page, Markdown & HTML for content.
  2. For a new page, use Meta Tag Generator, then Open Graph Generator and Open Graph preview for social sharing.
  3. If you write or convert, go through Markdown preview, Markdown to HTML, or HTML to Markdown depending on the direction you need.
  4. To check an existing site, choose Web Diagnostics with HTTP header analysis or Web Performance with Page weight and Site speed test.

Frequently asked questions

How many subcategories are in this universe?

The Web & Sites universe has five subcategories: Tags & Metadata, Markdown & HTML, Web Diagnostics, Page Utilities, and Web Performance. It contains twenty-two free tools. You can start with the subcategory tied to your task.

Are these tools useful for a site already online?

Yes. Several tools help check or improve an existing page, such as Web Diagnostics or Web Performance. Others help prepare tags, content, or campaign settings. All are free and require no sign-up.

Where should I start for a new page?

Start with Tags & Metadata for the core elements, then move to Markdown & HTML if you write the content. Page Utilities can then complete a campaign, and Web Performance helps review assets. Each tool works on its own and is free.

Which tool should I choose for a technical diagnosis?

Look first at the Web Diagnostics subcategory. HTTP header analysis inspects the status and headers of an address, while Verify a redirect follows status and destination. For layout, Breakpoint tester shows which thresholds match a width.

How do I prepare social sharing for a page?

Begin with Open Graph Generator to compose sharing information. Then check the result with Open Graph preview. If the general tags are missing, complete them with Meta Tag Generator before finalising.
