Introducing Cascode — an open-source playground for learning distributed systems by building and breaking real AWS architectures.
Drop Lambda, SQS, DynamoDB, API Gateway, and 7 other AWS services onto a canvas. Wire them together. Hit simulate. Watch messages flow through your architecture in real time. Then inject a failure and watch it cascade.
What it does:
Drag-and-drop AWS architecture canvas with live message flow simulation
AI Design Doctor that grades your architecture A-D and catches anti-patterns
10 hands-on challenges (from "Build a REST API" to "Design a saga pattern")
Export to production-ready Terraform HCL or CloudFormation JSON
Real-time fault injection — kill a node and see what survives
Architecture validation with 100+ AWS best-practice rules
