Cloud diagrams
Draw AWS, Azure & GCP architecture — free, in your browser.
A free cloud architecture diagram tool with the real service icons built in. No SVG hunting, no broken logos, no sign-up. Type a slash, grab the service, wire it up — then hand the whole board to your AI.
Every cloud, every service — already built in
No more digging through icon packs or pasting blurry logos. Over 1,100 official cloud service icons ship with Outwin, plus 660 tech and brand logos for everything else in your stack.
Map any stack in seconds
The flow is built for speed — you stay on the keyboard and the diagram keeps up with your thinking.

1
Press / on the canvas
A command palette opens right where your cursor is. No menus, no toolbars to hunt through.
-
2
Type
aws,azureorgcpThe picker filters instantly to that provider. Keep typing —
/aws lambda,/gcp run,/azure cosmos— to jump straight to the service you want. -
3
Grab the service & wire it up
The real icon drops onto the board. Pull an arrow to the next box, and ghost-suggestion pills offer the natural next step so the diagram almost draws itself.

Smart auto-layout tidies it
As the architecture grows, a homegrown layout sweep nudges boxes apart so nothing overlaps — your diagram stays readable without manual fiddling.
Why cloud engineers diagram here
Real, current service icons
302 AWS, 628 Azure and 216 GCP icons, pulled from the official sets and kept pixel-perfect — so your diagram reads as exactly the services it shows.
No more SVG hunting
Stop tab-hopping to find a logo, downloading a zip, and fixing broken fills. Press /, type, done — the icon you need is already here.
Smart auto-layout
A side-constrained overlap sweep keeps boxes spaced and lines clean as you add services, so a sprawling stack never turns into a tangle.
Private & offline
Everything runs in your browser with no account and no server. After the first load it works offline, so even sensitive internal architecture never leaves your machine.
AI-readable handoff
Export to clean HTML and PNG. The HTML keeps your boxes, labels and connections as structured markup an LLM can actually parse — not a flat picture.
Built for speed
Local-first and keyboard-driven. The canvas opens instantly, ghost-suggestion pills propose the next box, and you sketch a deployment as fast as you can describe it.
Then hand it to your AI
This is the real reason engineers diagram in Outwin: every board exports as AI-readable HTML. Drop the file into ChatGPT or Claude and ask for the Terraform, an infrastructure review, or the docs — the model sees your services and how they connect, not a flat screenshot. The diagram becomes a prompt.
Why it's free and private
Outwin runs entirely in your browser. There's no account and no server, so your architecture never leaves your machine — which makes it safe to diagram even sensitive internal systems. It's free with no catch, and works offline once it has loaded.
Built for cloud engineers
- Forward-deployed and AI engineers prototyping a deployment before the code exists.
- Solutions architects sketching a reference architecture for a review.
- Backend and platform teams turning a whiteboard session into IaC with an LLM.
- Anyone documenting a system who's tired of fighting a heavyweight diagram tool.
