## Project history and usage

Authz0 is a Go CLI for automated authorization and access-control testing. It models target URLs, roles, assertions, and credentials in YAML templates, then scans for unauthorized access based on those role definitions.

### Project history

The public repository was created in January 2022. The README describes the tool as an automated authorization test tool that identifies unauthorized access using URLs, roles, and credentials.

Early releases moved quickly: v1.0.0 shipped in January 2022, v1.1.0 added `setCred` plus imports from ZAP, HAR, and Burp history, and v1.1.2 followed in March 2022. The repository has continued to receive activity even though Homebrew currently tracks the older 1.1.2 release.

### Adoption history

Authz0 is distributed through Go install, Homebrew via the project's tap instructions, Snapcraft, Docker, and a GitHub Action according to official docs and the README. The Homebrew core formula packages 1.1.2 from the official GitHub tag, while the input also records Nix packaging.

The tool sits in the bug-bounty and application-security packaging lane: small enough to install as a single CLI, but designed to consume artifacts from Burp, ZAP, HAR exports, and YAML templates created during manual security testing.

### How it is used

A typical flow is `authz0 new` to generate a YAML template, `authz0 setUrl`, `setRole`, and `setCred` to add test data, then `authz0 scan` to execute checks. The docs show credential headers stored inside the user-supplied template file rather than a fixed global credentials location.

Because the template path is chosen by the user, there is no official fixed config-file or credentials-file location to record. The official structure docs document the YAML schema, not an application config path.

### Why package nerds care

Authz0 is notable for packaging a common appsec workflow as a reproducible CLI: collect URLs from ZAP/Burp/HAR, map roles to allowed and denied routes, and run the same authorization checks again in CI or local testing.

Its package history also shows the difference between upstream activity and packaged stable versions: the repository is active, while the Homebrew stable formula remains at the 2022 1.1.2 release.
