OpenAPI document viewer
View and statically inspect OpenAPI 3.0/3.1 JSON or YAML documents locally without sending sample requests.
How to use the OpenAPI document viewer
OpenAPI The document viewer processes input only in the current browser; it does not upload, access the network, or save user data.
Input content
Paste or load the OpenAPI 3.0/3.1 JSON/YAML document.
Select a processing method
Browse paths, operations, parameters, request bodies, responses, and local references, and view static issues.
Check and export
Copy the documentation summary or export the inspection results; no API requests will be executed.
Limitations and Notes
- Only local documents and local $ref are parsed; remote references and request execution are prohibited.
- The viewer is not a complete OpenAPI specification validator, nor does it prove that the interface actually works.
- The tool only provides locally processed results; important configurations, secrets, documents, and published content must still be reviewed in the target environment.
FAQ
Will the input be uploaded to a server?
No. The page only uses browser memory, the local file API, and local resources already provided with the site.
Will it call my interface according to the documentation?
No. The tool only creates a local document tree and static analysis results; it does not create network requests.
Why do the results still require manual review?
Edge-case syntax, regional standards, third-party readers, and target runtime environments may differ; the tool does not replace final validation.
