Validate AsyncAPI documents in the browser

AsyncAPI describes event-driven APIs: channels, messages, servers, and schemas for publish/subscribe systems. Paste YAML or JSON to check required fields, channel operations, and a quick summary of servers and components.

For REST-style HTTP contracts, use the OpenAPI Validator. This tool focuses on AsyncAPI structure rather than full schema dereferencing.
