Where each one falls short

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

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

Fastly

  • Bandwidth is priced per region, and delivery to India, Africa and South Korea is $0.28 per GB against $0.12 in North America and Europe
  • The same traffic therefore costs more than twice as much depending on where the audience is, which is invisible until the bill arrives
  • The free allowance is 100 GB of bandwidth and 1M requests a month
  • Requests are billed separately from bandwidth, at $0.01 per 10,000 above the first million
  • High volume rates past 50 TB are not published and require contacting sales

Answered from the vendors’ own pages

Buildah: Is Buildah free?

Yes, open source with no licence fee.

Fastly: Does Fastly charge based on usage or a flat monthly fee?

Fastly operates on a usage-based model with volume discounts. They offer a free tier with 100 GB bandwidth and 1M requests for experimentation, then customers pay per unit consumed with tiered discounts as consumption increases.

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.

Fastly: What are Fastly's main service packages and their costs?

Fastly offers Network Services Packages ($1,500-$6,000/month baseline), Security Packages (custom pricing), Compute Packages ($500/month entry level), and Observability Packages ($1,500/month entry level). Enterprise solutions include custom quotes for high-volume deployments.
