EAS Build Profiles

Three default profiles + how to extend them.

Credential and external action gate

Editing a local profile is safe. Creating EAS environment variables, reading or storing credentials, starting a cloud build, or changing a project setting is external and may incur cost. Obtain owner confirmation of the exact EAS account, project, environment, variable classification, and action first. Never place a server secret in an EXPO_PUBLIC_* variable or commit it to eas.json.

Default 3 profiles

• development — developmentClient: true, distribution: internal. Dev tools enabled. Install dev client on physical iPhone.
• preview — distribution: internal. Production-style binary for internal QA. Skips TestFlight processing wait.
• production — store-bound. No dev client, release config, signed with distribution cert.
