Questions & Answers

As answered by people managing Mermaid Viewer and Diffee.

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
