Compare changes between different versions and tags of your OpenAPI schema. Track evolution and identify breaking changes.
Get real-time validation and linting feedback. Catch errors early and maintain high-quality API specifications.
Seamlessly import existing OpenAPI files and export your work. Support for multiple formats and easy integration.
Get started with your OpenAPI schema in just a few simple steps
Upload your OpenAPI specification file or paste your schema directly into the editor.
Navigate through your API structure using interactive graphs and visual representations.
Make changes with confidence using real-time validation and comprehensive error checking.
The editor changes every week. Here are the last few releases — read the full changelog .
The editor now shows the OpenAPI version your document declares and creates new nodes using the constructs that version allows — a nullable field comes out as `nullable: true` on 3.0 and as a null type union on 3.1. Webhooks, 3.1's other root section, are visible and editable for the first time.
Import a YAML OpenAPI spec and it stays YAML — through editing, snapshots and export. No more round-tripping your document through JSON just to use the editor.
Responses now document their headers and body, endpoint descriptions render as markdown, and global search finds endpoints by URL fragment.
