プロジェクトの歴史

The public repository was created in May 2021 and early GitHub releases began with v1.0.0 in July 2021. It arrived after AWS CLI v2 added native SSO support, but focused on organizations with many accounts and many IAM roles, where plain AWS CLI profiles can become cumbersome.

The project evolved around two package-nerd concerns: a single static Go binary with official release artifacts, and a configuration model that could coexist with standard AWS CLI profile files. The documentation notes a move to XDG-style state under `~/.config/aws-sso` in v1.17.0 while keeping `~/.aws-sso` compatibility.

採用の歴史

Homebrew carries `aws-sso-cli` in homebrew-core, and the project documentation names Homebrew as a first-class installation path. Its GitHub repository metadata showed hundreds of stars and forks in June 2026, and Homebrew analytics showed hundreds of 30-day installs, indicating use beyond a single organization without making it a default AWS tool.

Adoption has tracked the AWS IAM Identity Center transition: the README explicitly notes that AWS SSO was renamed IAM Identity Center, while the underlying config fields and APIs still use SSO terminology. That made the package useful during the long period when project names, AWS docs, and API names did not all say the same thing.

使われ方

Typical use is `aws-sso` for guided setup, `aws-sso exec` or shell helpers to export short-lived STS credentials, and generated entries in `~/.aws/config` for tools that already understand AWS named profiles. The README emphasizes encrypted storage for AWS SSO client secrets, access tokens, and CLI cache credentials.

The tool is most relevant for developers who switch across many AWS accounts and roles, especially when the AWS web console and CLI both need fast profile switching.

パッケージ好きにとっての重要性

For package maintainers, AWS SSO CLI is an example of a post-AWS-CLI-v2 helper that did not just wrap `aws sso login`; it packaged a more opinionated identity workflow as one cross-platform Go binary. The Homebrew formula tracks upstream release tags, while upstream also publishes binary, RPM, and DEB artifacts.

Related projects

• The README compares AWS SSO CLI to `aws-vault`, noting overlap in secure credential handling but a stronger focus on IAM Identity Center instead of long-term API keys.
• `aws-sso-util` and `aws2-wrap` solve adjacent AWS SSO workflow gaps, especially profile generation, credential_process integration, or tools that lagged native SSO support.
