Getting Pro
There is no self-serve billing yet. During the preview, Pro is issued by hand: email hello@starwell.dev from the address on your account and we move your account and keys the same day. Pricing for general availability will be announced when card billing ships.
Free ceilings may be tuned during the preview. Full quota semantics are in the docs.
