I think closed source service stuff like this was long over before LLMs came along. Now it's like, I can take a few screenshots and make this myself. At least with open source YOU the developer get to carry on being in the conversation and co-develop, rather than giving ideas to others and being left out
The payment flow on the site is a simplified demo diagram. But you're absolutely right that stepping through a diagram like this is one of the best ways to catch edge cases before they become bugs, that's one of the core use cases we see.
Would love to know: is this something you'd use in PR reviews to catch issues like this early?
You’d also probably need some mechanism to visually diff the flowcharts to participate in discussions/changes
You could render this interactive diagram as a static sequence diagram quite easily. And then see all the relations in full glory at one time.
Others may feel different.
Would love to know what you'd use it for specifically — system design interviews, team demos, something else?
On extensibility, genuinely open to hearing what you'd want. What would "extensible" look like for your workflow specifically?
As for extensibility - I understand that your focus is system design, but I don't really see any reason for this to not be more broadly available for any sort of process design, particularly for use as a UX tool or in the product ownership space for understanding how systems and physical processes might be interconnected. I see that you can add any custom node in the code, and they just get a little gear icon, but it would be nice if the user could define the nodes themselves, add meta data, conditionals, loops etc. I've been using BPMN for years but I'd be lying if I said it wasn't outdated and a pain to present to people.
