The short version

  • Only Cloud Native Buildpacks has a free tier, so it costs nothing to try first.
  • Each has a real cost: Cloud Native Buildpacks the operational cost is real: you own builder images, base image refresh cadence and migrations between specification versions, which currently sit at Buildpack API 0.10 and Platform API 0.12 with published migration guides, so breaking changes are a recurring chore.; IAR Embedded Workbench no pricing information published on product page; prospective customers directed to free trial or sales contact only

Where each one falls short

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

Cloud Native Buildpacks

  • The operational cost is real: you own builder images, base image refresh cadence and migrations between specification versions, which currently sit at Buildpack API 0.10 and Platform API 0.12 with published migration guides, so breaking changes are a recurring chore.
  • A cold build with no warm cache is noticeably slower than a well layered Dockerfile, and because the cache lives in a cache image or volume, ephemeral continuous integration runners pay full price on every run unless you deliberately warm them.
  • Reproducibility depends on discipline rather than defaults, because buildpacks resolve runtime patch versions at build time unless you pin them and stability is only as good as the builder image tag you point at.
  • The specification is neutral but the buildpacks are not, and in practice you depend on Paketo, Heroku or Google, whose roadmaps, support levels and update cadences differ; CNCF also records contributing organisations down 12 per cent year on year.
  • Native dependencies, unusual monorepo layouts and non-standard project structures push you into writing custom buildpacks or extensions, which is a genuine engineering investment and not a configuration change.

IAR Embedded Workbench

  • No pricing information published on product page; prospective customers directed to free trial or sales contact only
  • Pricing model not specified; customers must request quote or try free trial to understand licensing costs
  • Embedded development tools typically require expensive licenses, but specific IAR costs unavailable online

Answered from the vendors’ own pages

Cloud Native Buildpacks: What does CNCF graduation actually change?

Nothing technically, but it signals audited governance, security review and multi-vendor maintenance, which is usually what a procurement or risk team needs before approving a build system.

IAR Embedded Workbench: How much does IAR Embedded Workbench cost?

IAR Embedded Workbench pricing is not published on the product page. Prospective customers are directed to free trials or must contact the sales team to request pricing.

Source
Cloud Native Buildpacks: How is this different from writing a Dockerfile?

Container build knowledge lives with the platform team in a builder image rather than in every repository, and rebasing lets you patch the runtime base of many images without rebuilding them.

IAR Embedded Workbench: Does IAR Embedded Workbench offer a free trial?

Free trials are available for IAR Embedded Workbench evaluation at https://www.iar.com/embedded-development-tools/free-trials, though specific trial length and limitations are not detailed on the product page.

Source
Cloud Native Buildpacks: Does it cost anything?

No. The specification and tooling are Apache-2.0 and free. You pay only if you buy commercial support for a specific buildpack distribution from Broadcom, Heroku or Google.

IAR Embedded Workbench: What is the pricing model for IAR Embedded Workbench?

The pricing model is not disclosed on the product page. Customers must contact the sales team to obtain quotes and understand licensing terms.

Source
Cloud Native Buildpacks: Is it slower than a Dockerfile?

On a cold build with no cache, yes. Warm builds are competitive, but continuous integration runners that start empty every time will feel the difference.
