Storage

Object storage with CDN distribution. Files, images, and documents with automatic optimization.

Queue

Background job processing with retry logic, dead letter queues, and priority scheduling.

Auth

Authentication and authorization. Email/password, OAuth providers, API keys, and role-based access control.

Observability

Logs, metrics, and traces. See what every service and agent is doing in real time.
