Frequently Asked Questions

What is Schema Doctor?

A free, open-source tool that validates and fixes OpenAPI schemas (JSON/YAML) to make them easier to use in automation workflows.

How is it different from other OpenAPI editors?

Schema Doctor focuses on repair and cleanup—fixing common problems like missing IDs, invalid regex, and circular references—rather than designing APIs from scratch.

Do I need to install anything?

No. Schema Doctor runs entirely in your browser. Just paste a schema or load it from a URL.

Can I use it with private APIs?

Yes. You can paste JSON or YAML directly for internal/private APIs.

What formats are supported?

• YAML (auto-converted to JSON)
• JSON (direct editing)

Will it change my API’s behavior?

No. It only modifies the schema, not the actual endpoints.

Is Schema Doctor free?

Yes—MIT licensed and open-source.
