AI Analysis

●MidSlickShip It

Functional Mermaid clone, but the official mermaid.live already does this without upsells.

Strengths

•Client-side rendering ensures diagrams never leave the browser for privacy.
•Shareable links encode state in URL without server storage requirements.
•Clean UI with instant SVG and PNG export buttons ready.

Weaknesses

•Competes directly with official mermaid.live which has more community trust.
•Admits being a SEO funnel for Moxie Docs instead of standalone.

Post Description

I've been slowly adding some new free tools to Moxie Docs (partly for SEO, partly to illustrate some of our feature sets before any commitment) for some reason this mermaid editor one blew up on Google rankings so I figured I'd share in case people find it useful! We also have ADR, AGENTS.md, LLMs, and a few other free tools.

An MCP server that gives AI assistants a live Mermaid diagram canvas

It wires Mermaid into the MCP ecosystem so an assistant can spit out diagram source and immediately open a live browser preview over WebSocket, with instant re-renders and SVG/PNG download. That glue — CLI + MCP server + live preview — is a small idea but a high-utility one for anyone iterating diagrams with LLMs; it doesn't reinvent Mermaid, it makes AI-driven diagram authoring actually usable.
