Facts

Website: dexidp.io
Price: Free tier
Free trial: Not stated

Deployment: Dex can be installed as a container image, deployed with a Helm chart, or built from source, and the site says it runs anywhere Go runs.
Features: Dex provides a single authentication layer so teams can add upstream providers without changing their application code.
Governance: The official site identifies Dex as a CNCF Sandbox project developed under CNCF governance.
Kubernetes: Dex offers a lightweight binary and official Helm chart for use alongside Kubernetes workloads.
Machine authentication: Dex documents OAuth2 token exchange for exchanging an existing access or ID token for a Dex-issued token, including for CI and other automated processes.
Security: Dex’s storage documentation says its backing storage can contain signing keys and bcrypt-hashed passwords and recommends transport security and database access controls.
Security reporting: Dex says GitHub and mailing lists are not appropriate for vulnerability reports and links to a security disclosure process.
Storage: Dex supports etcd, Kubernetes custom resources, SQLite3, Postgres, and MySQL for persistent state.
Support: Dex directs users to file issues for bugs and feature requests and offers general discussion through CNCF Slack and GitHub Discussions.
Token claims: Dex supports scopes and claims including email, profile, groups, federated identity, and offline access, subject to connector capabilities.
