Dev Hub
The control-plane org that creates scratch orgs and builds package versions for a team.
Definition
A Dev Hub is a production or Developer Edition org with the Dev Hub feature enabled, acting as the control plane for source-driven Salesforce development. It's what actually creates and tracks every scratch org a team spins up, and every package version built under 2GP gets registered against it, including the org's one namespace.
Each Dev Hub carries a daily and active scratch org limit, so a team typically runs one Dev Hub per registered namespace or product line, connecting to it with sf org login web --set-default-dev-hub and authenticating individual developers against it to create their own scratch orgs.
Losing access to a Dev Hub, or hitting its org creation limits, blocks scratch org provisioning and 2GP builds entirely, which makes Dev Hub capacity planning a real operational concern once a team scales past a handful of developers.
How it works in Serpent
Serpent manages Dev Hub connections and scratch org creation limits centrally, so no individual developer has to track quota or juggle CLI authentication against the Dev Hub directly. Scratch orgs pool and provision automatically as part of task setup, staying within Dev Hub limits without a team member having to watch usage manually. See 2GP CI/CD in Serpent for how Dev Hub-backed builds fit the pipeline.
