Field notes
The canvas supports both starter architectures and a blank design, with a palette that includes Redis, Postgres, Cassandra, DynamoDB, Kafka, and SQS. Users can adjust simulation speed, follow a request, and save runs to compare; designs can also be saved as reusable components or downloaded as PDFs. The page labels its first URL-shortener challenge as requiring no signup.
