Create Stunning Isometric Infrastructure Diagrams with FossFLOW
Ever struggled to make your infrastructure diagrams look polished and professional? Or maybe you just want to visualize your cloud architecture in a way that doesn’t look like a tangled mess of rectangles and arrows? FossFLOW is here to help.
This open-source tool lets you create beautiful, isometric (3D-style) diagrams right in your browser—no design skills required. Whether you're documenting a Kubernetes cluster, mapping out a microservices architecture, or just sketching a network layout, FossFLOW makes it easy—and actually fun.
What It Does
FossFLOW is a Progressive Web App (PWA) built with React and powered by the fossflow library (a fork of Isoflow). It runs entirely in your browser, supports offline use, and automatically saves your work. You can:
- Drag and drop pre-built components (servers, databases, networks, etc.)
- Connect nodes with clean, adjustable lines
- Customize colors, labels, and layouts
- Import/export diagrams as JSON
- Install it as a PWA for a native-like experience
Why It’s Cool
- No Account Needed – Everything saves locally in your browser (privacy-first).
- Auto-Save Every 5 Seconds – No more panic when your browser crashes.
- Offline Support – Work on diagrams without an internet connection.
- Keyboard Shortcuts – Undo/redo (
Ctrl+Z/Ctrl+Y), delete, and quick navigation. - Open-Source & Free – No paywalls, no proprietary lock-in.
How to Try It
You can start using FossFLOW right now in your browser:
Or, if you want to run it locally:
git clone https://github.com/stan-smith/FossFLOW
cd FossFLOW
npm install
npm start
Open http://localhost:3000, and you're good to go.
Final Thoughts
FossFLOW is one of those tools that feels just right—simple enough to jump into, but powerful enough to be genuinely useful. If you’ve ever wasted time fighting with clunky diagram tools (looking at you, Lucidchart), this is a breath of fresh air.
Best of all? It’s open-source, so you can tweak it, contribute, or even self-host it. If you’re into infrastructure visualization, give it a spin—you might never go back to boring flat diagrams again.
