OZ account-discovery CLI enters alpha

Use a standalone, read-only CLI to discover and explain AWS serverless resources from your terminal.

The OZ CLI is now available in alpha.

OZ, short for Open Zerverless, is a standalone tool for discovering and explaining serverless resources in an AWS account. It runs from the terminal and does not require a private zerverless service or product subscription.

What the alpha does

The first release focuses on read-only discovery of functions, APIs, event sources, queues, workflows, and the relationships between them. The output is intended to be reviewable in a terminal and useful as a starting point for documentation.

What it does not do

OZ does not modify, repair, or deploy AWS resources. The project stays separate from Air: OZ is a local open-source discovery workflow, while Air develops the hosted visual exploration experience.

Alpha expectations

Resource coverage and output formats will change. Use a scoped read-only role, start in a non-production account, and report account shapes that the discovery model does not explain clearly.
