Frequently asked questions

Is YAML a superset of JSON?

Yes, YAML 1.2 can read JSON, but block-style YAML is easier to read and edit by hand, which is why configs use it.

Is my data sent to a server?

No. Everything runs in your browser, so API keys, tokens, configs and customer data never leave your machine.
