MermaidEditor Comments & Reviews 2026

Black on dark gray. Basically, uselesss, text is black on a dark gray background making it almost impossible to see.

Basic and useful. This is a basic app that utilizes the Mermaid JS descriptor language. (You can Google "mermaid-js" online for a complete syntax guide; that's what I did.) By "basic", I mean you can input line-by-line Mermaid JS syntax and it will render the diagram. You can also paste into the syntax editor area. (I tested this, because a one-star reviewer claimed otherwise. I copied-and-pasted a complete diagram into a new document, and it rendered fine. I am on an "M1" iPad Pro. Perhaps that matters?) Why am I giving it five stars while another gave it one? Because it is literally exactly what I needed. It is a very simple mermaid-js editor and renderer. There are no bells. There are no whistles. I did not need to copypasta from elsewhere, in fact. I only needed to type in my diagram to see it graphically. This app can generate an SVG from the diagram, but I would have been happy if I could have only screen-captured it. So, I'm happy with the app. I have been working on a difficult problem at work. Visually tying together existing components diagrammatically made life easier because I could determine which existing components to use, and which pieces of code I still needed to write. This app was helpful for me.

Solid Mermaid Editor. I’m building a second brain out of plain text files, and this app expands what I am able to do. I’m excited to plan my projects with GANTT charts, make a timeline of my mom’s career, and create a family tree.

Doesn't Support mmd Files. Despite the first screenshot, the app doesn't actually support opening .mmd files, which really limits its utility.

Decent, but could use some improvements. Basically functions well. Pros: - Live editing. - Double-clicking an .mmd file does open the app, despite the other review. - pan and zoom of the diagram supported, though panning requires a click-and-hold, which is unatural for typical trackpad behavior on a Mac app (compare to the Maps app). - Generates diagrams from standard templates. - Link to the MermaidJS docs. Cons: - The cursor is almost invisible in the editor. I'm constantly losing track of it. - Needs better support for light/dark themes (this may help the cursor issue). - Large state diagram didn't render, and no errors were displayed. - Code completion only works for Mermaid key words, not user-defined symbols (compare to the official Live Editor)

Doesn’t open Mermaid files.. The irony of this app being called Mermaid Editor but not actually being able to gracefully open files with the .mermaid extension is laughable.

Useless without a select/copy/paste feature.. No way to get any useful interactions in or out of this without a clipboard.

Don‘t waste your time and money. PSA: Don‘t waste your time and money. The editor does not have clipboard functionality, so unless you are into typing mermaid files from scratch this app is useless.

Opens .mmd files, and can export PNG or SVG easily. I picked this tool up after getting frustrated with the bad export functionality of the Mermaid live editor. I often need to export my mermaid charts to PNG or SVG. This tool handles that case very well, and the edior panel is clean and has nice code highlighting. I do with the editor pane had a light/dark mode though, as the white background is brutal on the eyes at night.

Useless. Cannot paste diagrams, basic function

Needs work. Think I'll just stick with the web version for now. - files / Document view shows recents and recently deleted. Mermaid recents shows a bunch of iCloud files totally unrelated to Mermaid. One would expect that the director my would start fresh and have its own folder not Ben f shared across all your event files. Making it hard to locate or try and open a file you may want to sync. - UX is amateurish, the keyboard icon to edit is annoying, for an editor that is 99% keyboard driving this isn't logical. You should be focussed in the editor most of the time. The button to toggle is not a good experience at all. - rendering looks terrible, I currently see triangles and no connecting lines in a flowchart. - Navigating between documents view and editor view is lost in the interface. Deleting the app now, wasted a few $$ here

Can’t paste text. I can’t imagine a good reason why this ability would not have been added.

Usually fails. In general, not designed to be very usable. Will produce a diagram under the right circumstances, but more typically fails with “Importing module script failed.”

No documentation or supporting website. I wanted something to do quick and simple flowcharts and saw that this app would also do sequence diagrams, so I bought it. Unfortunately I can’t find any help, documentation, or even a support website to help me navigate this app. For that I’ll rate it 2 stars for now and, depending on how I make out with the app, will return to adjust my rating accordingly
