Show HN: APId – the API end to end testing framework has gone open source (getapid.com)

Not currently, but planning to natively supporting GraphQL, and adding support for websockets and grpc.

Co-founder here - we'll be happy to add this in the future like Ivo already said. If it is something that many people want, we'll add it sooner. It will be really helpful if you could submit a feature request issue on our github - https://github.com/getapid/apid-cli/issues/new/choose
