Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Arnica

Per-identity pricing ($25-$50/person/year) requires tracking active developers
Overage identity tracking via 90-day PR activity can be unpredictable
Free plan limited to weekly updates, requiring upgrade for real-time scanning
Advanced add-ons (Image Scanning, AI SAST, Agentic Rules Enforcer) pricing not published
On-premises deployment limited to Enterprise tier

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

Answered from the vendors’ own pages

Arnica: How are identities defined in Arnica pricing?

Identities are any users and other contributing entities that contributed code and/or had PR activity during the last 90 days. This ensures billing matches active developers.

Source

Buildah: Is Buildah free?

Yes, open source with no licence fee.

Arnica: What is the annual discount?

Annual prepayment offers approximately 17% savings versus monthly billing. Core Business annual is $300/identity versus $360 for monthly.

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.

Arnica: Can I cancel or downgrade Arnica anytime?

Yes. Subscriptions can be cancelled or downgraded at any time. Overage identities receive automatic protection with true-up invoicing.

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.
