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
ESLint
- Slow performance on large codebases compared to newer tools like Oxlint and Biome
- Complexity in configuration from scratch, particularly for TypeScript support
- Limited built-in TypeScript support, requiring separate parsers and coordination with new TypeScript features

Answered from the vendors’ own pages
Buildah: Is Buildah free?
Yes, open source with no licence fee.
ESLint: Does ESLint automatically fix code issues?
Many problems ESLint finds can be automatically fixed via the --fix flag. ESLint fixes are syntax-aware so you won't experience errors introduced by traditional find-and-replace algorithms.
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.
ESLint: How much does ESLint cost?
ESLint is completely free and open-source software maintained by the OpenJS Foundation. The project accepts voluntary donations from sponsors.
SourceBuildah: 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.
ESLint: Can I write custom ESLint rules?
Yes. You can develop custom rules that work alongside built-in functionality through ESLint's plugin system, allowing complete customization for your project needs.
