Nori looks really cool, will set up sometime to exchange notes. But with regards to your questions: - Proxying keys: We allow users to setup keys in the sandbox and use CLIs for some cases but we also support an egress gateway that intercepts and injects keys on the way out, which supports the major api integrations we offer. - We still allow fly.io for deployments (so after a sandbox has a final app, you can deploy it and move out of the ephemeral sandbox). We never used them for sandboxing, but we will integrate into https://sprites.dev/ soon. - For the CLI, we allow you to SSH into the remote sandox since a lot of workload add too much stress to local machines

Curious about what sandbox provider you use to power Nori and how you are handling the secrets/keys issue?
