Auth0

  • Free tier limited to 25,000 monthly active users, requiring upgrade for growth beyond that
  • Advanced features like MFA and RBAC only available on paid Essentials tier and above
  • Ownership by Okta introduces risk that independent product roadmap may change

Buildah

  • Linux only, with no native macOS or Windows support
  • Scriptable builds are powerful but less portable and less familiar than a Dockerfile
  • Narrow by design: it builds images and does not run them, so it needs Podman or another runtime alongside

Buildah: Is Buildah free?

Yes, open source with no licence fee.

Auth0: Does Auth0 include Multi-Factor Authentication?

No. MFA, RBAC (Role-Based Access Control), and premium support are not included in the free tier and require upgrading to paid Essentials plans or higher.

Source
Buildah: Do I still need a Dockerfile?

No. Buildah reads Dockerfiles if you have them, but images can be built entirely from shell commands instead.

Auth0: Is Auth0 independent or part of a larger company?

Auth0 was acquired by Okta in May 2021 for $6.5 billion. It now operates as a subsidiary business unit within Okta, but maintains its own brand and operations.

Source
Buildah: How is Buildah different from Podman?

Buildah builds images; Podman runs them. Podman actually embeds Buildah for its build command, and the two are designed to be used together.

Auth0: Who should use Auth0 vs Okta?

Auth0 is developer-focused and serves customer identity use cases (B2C). Okta serves workforce identity (B2B) and has broader enterprise features. Auth0 now serves both markets post-acquisition but maintains its developer-friendly positioning.
