I love ASCII diagrams! The fact that I can write a diagram that looks equally wonderful in my terminal via cat as it does rendered on my website is incredible.
A good monospaced font and they can look really sharp!
I will definitely give this tool a shot.
I will also shout out monodraw as a really nice little application for building generic ASCII diagrams- https://monodraw.helftone.com/
While great for individuals, it's particularly strong out-of-the-box for teams, or even teams of teams with two levels of grouping.
They bring the same ... craft (ahem) ... to the whole product as shown in their Craft Agents or this renderer, with a strong foundation originally started in the Markdown philosophy. Check out the founder's story on their About page for a refreshingly LLM-free backgrounder.
The devs should really setup a client-only GitHub Pages for an accessible demo. Judging from skimming the project itself, it's definitely doable without locking into their platform.
While Mermaid gets the limelight, Kroki[1] offers: BlockDiag, BPMN, Bytefield, SeqDiag, ActDiag, NwDiag, PacketDiag, RackDiag, C4 with PlantUML, D2, DBML, Ditaa, Erd, Excalidraw, GraphViz, Nomnoml, Pikchr, PlantUML, Structurizr, Svgbob, Symbolator, TikZ, Vega, Vega-Lite, WaveDrom, WireViz, and Mermaid.
My Markdown editor, KeenWrite[2], integrates Kroki as a service. This means whenever a new text-based diagram format is offered by Kroki, it is available to KeenWrite, dynamically. The tutorial[3] shows how it works. (Aside, variables within diagrams are also possible, shown at the end.)
Note that Mermaid diagrams cannot be rendered by most libraries[4] due to its inclusion of <foreignObject>, which is browser-dependent.
The ASCII output is the missing piece for AI-assisted coding workflows. LLMs can spit out Mermaid, but you can't see the diagram inline in a terminal/code-review context. This fixes that.
I have a list of text to diagram tools here https://xosh.org/text-to-diagram/ but not many are text to ascii. There are a few text to ascii sequence diagram tools.
I've had issues with other CLI wrappers there. ASCII output is a nice touch for including diagrams directly in code comments without breaking formatting. Does it handle large graphs well, or does the text wrap get messy? We tried using `graph-easy` for this before but the syntax was annoying. 6.
I get a sense of deja vu. There was another such project posted within the last 3 months, and another within last 6 months. I should have bookmarked them, because at least one of them was an open library (I think).
In the live demo, I am confused about some of the ascii renderings. (Unless I am missing something, they appear incorrect/inconsistent with the SVG.), https://agents.craft.do/mermaid
So for the "All Edge styles"
graph TD
A[Source] -->|solid| B[Target 1]
A -.->|dotted| C[Target 2]
A ==>|thick| D[Target 3]
(The svg for this example is maybe misleading, as it looks like un upside down T) But the ascii here has the overlapping words, and you cannot tell the difference in any of the lines.
The actual Mermaid ASCII renderer is from another project [0]. This project transliterated it to typescript and added their own theming.

Thanks for the credits!

Importantly they also render in your source code. I love a good diagram at the top of a file.
^Unicode.
Wow! It has this:
With this, you should be able to approximate swim lane diagrams, which is something Mermaid lacks.The last time I checked, Mermaid couldn't render subgraphs in a different direction than the overall graph.
If you like Obsidian.md but can't quite recommend it for less technical folks, these devs' Craft notes spaces are a great alternative:

The live demo requires some download of an AI agent platform? I'd really like to try this but not if that's what's required.

Also see https://arthursonzogni.com/Diagon for text to ascii.

Pair this with Unicode plots[0] and you're set!

Nice one! I had my own spin on this issue as well, but from the other angle https://github.com/probelabs/maid
Getting AI to generate valid mermaid diagrams on scale extremely hard. With maid i'm hitting 100% accuracy.
Maid is basically built from scratch mermaid parser, without any dependnecies, which knows how to auto-fix common AI slop diagramming issues.

Im sold. Love mermaid but totally agree.
How is the LaTeX compatibility? Base mermaid's LaTeX compatibility is quite sparse.
This is great, I will definitely make use of this!

Results in the ascii (The svg for this example is maybe misleading, as it looks like un upside down T) But the ascii here has the overlapping words, and you cannot tell the difference in any of the lines.The Parallel links, example mermaid
