mimicplus

Record a HAR, get a versioned spec, a typed Python client, OpenAPI, and a breaking-change check.

HAROpenAPIPython

mimicplus turns a HAR recording — the network traffic an app actually made — into a versioned specification, a typed Python client, OpenAPI output, tests, and a check that fails when a field disappears.

That last part is the point. Most API breakage is silent: a field vanishes, a type drifts, and the client finds out in production. mimicplus makes the breakage a build failure.

It is built for the person who owns an integration and wants a receipt for what the API did, not a promise about what it should do.
