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
Render
- The free Hobby workspace is limited to 25 services and 5 GB of bandwidth
- Every paid plan charges the workspace fee plus compute on top, so $25 per month for Pro is a floor rather than a total
- SAML SSO and SCIM require the Scale plan at $499 per month
- HIPAA-compliant workspaces, inbound IP rules and advanced RBAC roles are Scale plan features
- Organization-level audit logs require Scale; Pro provides only workspace audit logs
- Contractual uptime SLAs, support response SLAs and a technical account manager are Enterprise only, and Enterprise is custom priced with no published rate
- Included bandwidth is 25 GB on Pro and 1 TB on Scale, with usage beyond that billed separately

Answered from the vendors’ own pages
Buildah: Is Buildah free?
Yes, open source with no licence fee.
Render: What is Render's pricing?
Render's pricing details are not disclosed on the public pricing page. The site references workspace plans, compute services, and features but does not display specific costs. Users must visit the pricing page directly or contact Render for detailed information.
SourceBuildah: Do I still need a Dockerfile?
No. Buildah reads Dockerfiles if you have them, but images can be built entirely from shell commands instead.
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.
