I can blast out auto-reflowing flowcharts in Flying Logic on a keyboard but it's moved to a subscription model that doesn't make sense for my irregular use.
Seeing the connections in real time really helps with my thought process.
If you also want to interact with the diagram itself to make the changes, you can do that using the Mermaid Chart Playground: https://www.mermaidchart.com/play
For diagramming and even UI prototyping I keep getting back to plain old ascii drawings though. Asciiflow.com is fantastic. I just wish they had vim keybindings. It's also great to embed in .md too. Could mermaid generate ascii? It just seems easier to comprehend and doesn't need a separate renderer.
Honestly, I'm surprised anyone on HN would defend that sort of behavior.
I am Knut Sveidqvist, the inventor of Mermaid and creator of the Mermaid open-source project. I'm also the co-founder of Mermaid Chart.
To address the confusion: Mermaid Chart is not a separate entity "profiting off the name" - it's a commercial offering I created to help sustain the open-source project. Working on Mermaid during evenings and weekends became unsustainable as the project grew. Mermaid Chart allows me to work on what I love full-time while providing resources back to the open-source project. This support will continue to grow as our business matures.
I appreciate your concern about protecting users from deceptive practices. In this case, there is a direct connection between the open-source project and the commercial offering, created by the same founding team.
Now, we have added lots of new functionality. Proper editing with syntax highlighting, etc. Apart from that, we have also added integration with GitHub Copilot, so you can generate diagrams from code and continue to edit them using the extension.
