A canvas for system design with the real parts of AWS, Google Cloud, Azure and Kubernetes. Push traffic through it, walk a request across it, and share it with a link. No machine needed.
Real parts
Every card is a real service with its official logo, not a grey box with a label. Put an EC2 in a VPC, a Postgres on it, and the canvas knows what each one is.

Templates
Interview classics and real cloud layouts. Open one to look around, then press Edit to make it yours.
A classic web app on AWS: CDN and WAF in front, an Auto Scaling app tier behind a load balancer, and a Multi-AZ database in private subnets.
The shared VPC of a host project with prod and shared-services subnets, an HTTPS load balancer behind Cloud Armor, Cloud NAT, central logging and an HA VPN to on-prem.
A production Kubernetes cluster laid out the recommended way: ingress, namespaces, autoscaled deployments, default-deny network policies and stateful storage.
Simulate
Drag the traffic up, take a zone down, and watch every part fill up. The bottleneck, the latency, the success rate and a rough monthly cost update as you go.
Flows
A flow plays a request across the lines you drew: what the browser asks, where the cache answers, what happens on a miss. Anyone reading the design follows the same path you meant.
Write-up
Requirements, estimates, the API, the trade-offs. Type @ to point at a card on the canvas, so the reasoning and the drawing never drift apart.
Share
Publish a design and send the link, or embed it in a blog post. Readers can look around the full canvas, read the write-up and play the flows, then clone it into their own account.

For hiring
Give candidates a starter design or a blank canvas. Reviewers read the design, the write-up and an AI review side by side, instead of a photo of a whiteboard.
Free to start. Pick a template or a blank canvas, and share the link when it holds.
