## What it is
A CLI tool that converts mitmproxy traffic captures (and HAR files) into OpenAPI 3.0 / Swagger specifications. It lets you reverse-engineer undocumented REST APIs by capturing HTTP traffic and merging results into an existing schema.

## Use cases
- generate openapi spec from captured http traffic
- reverse-engineer an undocumented rest api
- convert mitmproxy flow file to swagger
- create api documentation from har file
- document a mobile app's backend api
- merge multiple traffic captures into one api spec

## When to choose
- you need an OpenAPI spec for an API with no existing documentation
- you can capture the API's traffic via mitmproxy or browser DevTools HAR export
- you want to incrementally extend an existing schema with new captures

## When to avoid
- you need to document GraphQL or non-REST APIs
- you already have hand-written OpenAPI specs and just need editing tooling
- traffic is encrypted and you cannot set up a MITM proxy
