Which one
Hermit — learning, small projects, single web apps. Plenty for most things.
King — bigger builds, multiple services, heavier AI workloads. Double the storage.
Coconut — same compute as King, but 50 GB disk. For projects that need space.
Paused billing
Metered agents still cost a small amount when stopped (storage). Flat rate is flat regardless.
