AsyncAPI Studio

What AsyncAPI Studio is

AsyncAPI Studio is a free, open-source tool for developing and working with AsyncAPI documents. It can validate documents, convert them to the latest version, preview documentation and visualize event flows. Documents can be written in JSON or YAML. Studio imports documents from remote URLs and resolves relative references against the remote URL. For local projects, it can resolve references after you grant access to the folder holding the documents and schemas. Listed referenced schema formats include Avro, JSON Schema and YAML. Users can edit the main document and referenced schemas, with the parser validating changes. Files opened from a folder can be saved in their original location; other files can be exported to a selected local file. The tool also provides a Markdown preview with Mermaid diagrams and an Avro schema viewer that generates Mermaid diagrams. It can run in a browser, locally, in Docker or as a Docker Desktop Extension. Local folder access is supported in Chrome, Edge and Brave, but not Firefox or Safari, and permission must be granted again each session. The project says the application is under development and may have breaking changes.
