It works by automatically changing CSS classes, and it looks like the underlying isoflow library should support this.

Looks great! One recommendation, move the screenshots more to the top of the readme. It says "Stylus (style + status)" first sentence, and leaves the reader with a dangling "so what is the style?!" until way lower, after a theory of operation section ;)
mmastrac 3 days ago [-]
Thanks for that feedback, will totally do that. I should probably update the sample screenshots to be a little more visually appealing, as well.

This looks amazing. I find Mermaid.js ugly and the syntax difficult/buggy but unfortunately it's one of the best supported diagram tools in static site generators. It'd be awesome to have Isoflow diagrams embedded in Markdown like that.

I love the idea of mermaid but the syntax is somewhat convolutes and the integrations in tools like GitLab are very unstable.

I don't know why, but I find the syntax pretty decent when you get used to it. It's declarative.
SOLAR_FIELDS 4 days ago [-]
That's more of a takedown of whoever built the Gitlab tool than Mermaid itself.
In the world where LLM's are very good at mermaid diagrams is the syntax even that terribly important?

What a terrible take
Tsarp 3 days ago [-]
I had the same issue. I found this and it works decently well and OSS.
I always loved the isometric diagrams on Clive Maxfield's [1] books about electronics. Since a lot of circuits are non-planar (flip flops, semiconductor layers, FPGA architecture), adding a perspective view makes things uncluttered, and easier to understand and remember. I think it translates well to many technologies.
This is immediately what I thought of. Terrible name collision.

It's a bit confusing to see "openflow" diagrams that include network components, that have nothing to do with OpenFlow. https://en.wikipedia.org/wiki/OpenFlow
It is unrelated, right? Just a name clash with an overlapping domain?

I've not done anything special here, just wrapped the community edition of ISOFLOW https://github.com/markmanx/isoflow
and made it dead easy to set up and run.
You can now export and load JSON backups of your diagrams allowing you to essentially have as many as you want, which the community version of ISOFLOW restricts. Enjoy!

I'm not very familiar with Node.js. Any idea where in isoflow's code are the graphics for those 3D-style icons? Are they SVG or what? Is it possible to add custom icons?
I was curious also.
The SVGs for the isoflow library of icons is in node_modules/@isoflow/isopacks/dist/isopacks.md
(yes, svg within base64 within markdown)

No you're absolutely right, isoflow is doing 90% of the work here, I'm not hiding that, they just don't have a ready to use version like this of their community pack. That's all this is.

You aren't hiding it, but the announcement and first paragraphs in the README suggest otherwise. It comes off as a bit disingenuous, perhaps you are not aware of this?

Diagrams look great - well done.
Reminds me of a similar project years ago that was doing the same thing - they ultimately struggled with monetization and folded (I forget the name) -- however this one is MIT OSS, so I'm guessing that's not a key concern right now.
Thanks! I can't take any credit at all for the icons/design that's all Isoflow, but their community edition is designed to steer you to the pro version.
No plans at all for money making, just want people to enjoy using it.
Thank you for pointing out the link, I'll get on that ;)

it would be great to have an easier time to add my custom icon svg or even links to svg and then scaling them automatically to size

I'm inclined to agree with Edward Tufte - the 3D part doesn't add any information to the diagrams, so it is superfluous
StrangeOrange 4 days ago [-]
Interesting visuals change the way in which people engage with a diagram. You can think of it as an aspect of storytelling. Personally I find my eyes much more likely to be drawn to these isometric diagrams, compared to a 2D equivalence. The 3D aspect draws my eyes in and keeps them there. So what's being added doesn't need to be raw information that changes the facts of a diagram, it can be an aid to processing. There's a reason that visual design is a thing.

This is a little tangential, but I've wondered for a while if there's a better way to visualise the composition of software systems.
Often, there's not only a single way to look at one: There's a user interaction flow through components, but those components also consist of hardware; the hardware might be virtual and composed of several, spread, sub-components, or even containers. You can go down this path pretty deep, and arrive at several different representations of the system that are either impossible to visualise at the same time, or make it incomprehensible.
Ideally, I would want to have a way to document different facets of the system individually, but linked to each other, and be able to change my perspective at anytime. This would allow to flip between UX, network traffic, firewall boundaries, program flow, logical RPC flow, and so on; all while being able to view connected components for a given component at anytime. For example, inspecting an application, then viewing its network ports, then its runtime container, the hypervisor the container runs on, the cloud provider that sits in, and so on.
My idea so far is a graph database that contains all components and the edges between them. The tool would have to be as extensible as possible, so using something like HCL to describe the graph would be great, with extensions for all kinds of components and edges. And finally a viewer to render visual representations of one or more composable layers to flick through, and export etc.
I never got around to working on it yet, but if anyone else had the same idea, I'd be open to collaborating :)
alixanderwang 4 days ago [-]
At least for the layering + using text aspect, D2 support this:
Terrastruct looks really nice, and kind of like a 2D version of the 3D thing I'm thinking of; if you could attach key-value properties to nodes and vertices, and had different rendering modes that made use of any of these properties to render the item differently, that would probably be pretty close. For example, a layer that displays a physical network might only consider vertices with a `kind` attribute of "physical link"; that limits the layer to all nodes with a matching vertex between them, and the layer would also only display those attributes of the nodes relevant for the current view.
Whoa as an infrastructure guy I had always dreamed of diagrams like this. And while I've used Miro and some OSS homebrew stuff, nothing was as polished as this. Well done.
aitchnyu 4 days ago [-]
Wonder why Mermaid has more hype than this.
billyp-rva 4 days ago [-]
There are quite a few tools that offer this model-based approach; you define your resources in a model, then use them in multiple perspectives to show different aspects like you describe. Some, like Ilograph[0] (my project), offer interactivity and zooming.
Some very good points, I totally agree, I suppose as you said you get to a point in your abstraction where it either loses meaning or becomes too complex to view. I think it would be a fantastic thing to try! Go build it!
Kudos—OpenFLOW feels like reclaiming infrastructure from CLI sprawl. Low-code network management with observability baked in is a powerful combo. The secret sauce is that it keeps humans in the loop: scripting flows is easy, but visualizing and validating them in real-time makes it production-ready. That human-checkpoint mindset is where dynamic tooling meets trust.
b0a04gl 4 days ago [-]
what if we can make these diagrams synchronized with reality. you need the diagram to pull from the same source of truth as your actual infrastructure - whether that's terraform state, kubernetes manifests, or service discovery. that way diagrams become less historical artifacts and more of living documentation
oddlama 4 days ago [-]
I've written something like this for NixOS a while back [1], which generates infrastructure diagrams directly from the source of truth (albeit not as pretty as isoflow). I'm sure this could be applied to other declarative tech stacks aswell!
That's a great thought, I'd need to make some kind of translation between manifests and the json, getting knowledge of those relationships might be tricky?
Service discovery is another route, would hate to get someones IT department angry for aggressive port scanning though lol

Cloudcraft[1][2] can do that with your cloud provider, AWS or Azure. As a bonus, the diagrams also look quite cool.

Nah, its okay. I too think beautiful is used too often in contexts where it feels exaggerated. Nature can be beautiful. People can be beautiful. But a blue and grey computer diagram? It certainly looks good to me but I would not use the word beautiful. Perhaps if it were exceptionally artistic using a unique aesthetic I would use that word. But that's just like, my opinion, man.
