Glad to hear you signed up for the beta. We've been letting people off in batches and hope you can use CockroachCloud for your apps! If you have any feedback on the beta product, do let us know!
CockroachDB managed service is available today - you can sign up on the website and we'll get in touch with you https://www.cockroachlabs.com/get-cockroachdb/
We will release a self-service offering where you can set up a managed cluster without having to talk to us later in the year.
Re: pricing, we have different packages based on # of nodes, and size of node (storage, vpcu etc.) and happy to share that in a call.
