Mermaid Viewer
ShellNewHandler

Overall verdict

  • Mermaid Viewer appears to be a useful, lightweight online tool for rendering and viewing Mermaid diagrams without needing to install any software, making it convenient for quick visualization tasks and sharing diagram code.

Why this product is good

  • Provides instant, browser-based rendering of Mermaid syntax without installation
  • Free and accessible tool for quick diagram previews
  • Simple interface that lowers the barrier for creating flowcharts, sequence diagrams, and other Mermaid-supported visuals
  • Useful for documentation, technical writing, and collaborative diagram sharing
  • Supports quick iteration since changes to code can be previewed in real time

Recommended for

  • Developers who need to quickly visualize Mermaid diagram code
  • Technical writers creating documentation with flowcharts or UML-style diagrams
  • Students or educators explaining processes or systems visually
  • Teams collaborating on architecture or workflow diagrams without heavy design tools
  • Anyone wanting a fast, no-install way to test or preview Mermaid syntax

Overall verdict

  • ShellNewHandler is a niche, lightweight utility hosted on SourceForge designed to give users more control over the Windows 'New' context menu (the ShellNew menu). It can be considered good for its specific narrow use case, but it is an older, minimally maintained tool that may not suit all users, especially those on modern Windows versions.

Why this product is good

  • Provides direct control over customizing the Windows right-click 'New' menu, allowing users to add or remove file type entries
  • Lightweight and free, without bundled bloatware typical of some other free utilities
  • Simple and focused in scope, making it easy to understand for its specific purpose
  • Open distribution via SourceForge allows transparency and no-cost access

Recommended for

  • Power users who want to declutter or customize the Windows New context menu
  • IT administrators managing standardized desktop environments across multiple machines
  • Users comfortable with older utility-style tools and Windows registry-related tweaks
  • Not recommended for casual users seeking modern, actively supported software with regular updates

Questions & Answers

As answered by people managing Mermaid Viewer and ShellNewHandler.

What's the story behind your product?

Mermaid Viewer's answer

Mermaid Viewer started from a simple need: having a quick place to view and experiment with Mermaid diagrams without setting up a full editor or documentation site. I often needed to test Mermaid snippets, share diagrams with teammates, and embed them into docs, so I built a small tool for myself. Over time it evolved into Mermaid Viewer, a dedicated online viewer and editor for anyone who wants a fast, no‑friction Mermaid experience.

How would you describe the primary audience of your product?

Mermaid Viewer's answer

The primary audience is developers, technical writers, product managers, and engineers who document systems, architectures, and workflows using Mermaid diagrams. It’s especially useful for people who work with Markdown, wikis, and code repositories and need a quick way to prototype or share Mermaid diagrams.

What makes your product unique?

Mermaid Viewer's answer

Mermaid Viewer provides a focused, distraction‑free place to create, preview, and share Mermaid diagrams in the browser. It combines a clean editor, instant live preview, and shareable links so people can quickly turn plain‑text Mermaid syntax into clear diagrams without installing anything.

Why should a person choose your product over its competitors?

Mermaid Viewer's answer

Mermaid Viewer is lightweight, fast, and built specifically for Mermaid. There is no complex setup, heavy UI, or vendor lock‑in – just a simple way to paste or write Mermaid code and immediately see the rendered result. It works directly in the browser, plays nicely with existing tools, and is ideal for people who want a minimal, reliable Mermaid playground.

Who are some of the biggest customers of your product?

Mermaid Viewer's answer

Software engineering teams Technical documentation teams Product and UX teams Individual developers and technical writers

Which are the primary technologies used for building your product?

  • I recently got libreoffice, but now the new option in right click looks like a mess. Can someone help me get rid of them please?
    Use Shell New Handler. Run the portable app and simply untick the items you don't want to appear in your new context menu. Source: about 4 years ago
  • This menu should be easy to add/remove programs to... Who is really creating Access Databases from this menu often enough to keep it here? (Not me!) Is there an easy way to edit this?
    I've always used ShellNewHandler for this. It's a really simple portable utility that allows you to remove most of the items from that menu. Tested it out on Windows 11 and it's still compatible. Source: over 5 years ago
