Looks promising. There are a couple of things that worries me though. (I haven't tried it yet, only skimmed the docs)
1. Telemetry needs to be opt-in during install. 2. The roles are weird, why would a developer need write access by default? That's just a recipe for disaster. Would be better to default to read-only in all roles and allow upgrading to write permission as an active choice. 3. There needs to be a clear way to distinguish between prod/staging. I like clients where you can change the background color for different connections, eg screaming red for prod.
Good luck, keep up the good work
