What is HAR to OpenAPI?
Generate a reviewable OpenAPI 3.1 contract from requests and responses observed in one or more browser HAR captures. The tool groups operations, merges schema evidence, preserves error responses, and clearly marks uncertain inference.
How to use it
- 1.Drop one or more `.har` files or load the safe example.
- 2.Include the API domains you want documented.
- 3.Inspect operations and resolve items under Needs Review.
- 4.Review validation, then copy or download YAML or JSON.
Privacy and limitations
Parsing and inference run locally in your browser. Common credentials, cookies, signed URL fields, and secret body values are removed before inference. A HAR is observed evidence rather than a complete backend contract, so review the generated specification before relying on it.
