Is Packer or Stable Diffusion better?

Neither clearly leads. Packer starts at Free and Stable Diffusion at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.

Which is cheaper, Packer or Stable Diffusion?

Packer starts at Free and Stable Diffusion at Free.

Does Packer or Stable Diffusion run on more platforms?

Packer runs on Linux, Windows, Mac. Stable Diffusion runs on Web, Local (GPU-based), Cloud APIs.

Can I use Packer for free?

Both have a free tier, so you can try either at no cost before committing.

What is Packer best used for?

Packer is most often used for building identical machine images for multiple clouds from one template, baking golden amis and vm images into a ci pipeline, creating immutable infrastructure artifacts consumed by terraform. Of those, building identical machine images for multiple clouds from one template and baking golden amis and vm images into a ci pipeline are not what Stable Diffusion is typically brought in for.

What can Packer do that Stable Diffusion cannot?

Packer covers Image building, Multi-platform support, Provisioners, Builders. Stable Diffusion covers Text-to-image, Image-to-image, Inpainting, LoRA support.

The short version

Each has a real cost: Packer packer 1.10.0 and later is licensed under the Business Source License 1.1 with IBM Corporation as licensor, not an OSI open source licence; Stable Diffusion generated images have lower resolution and quality at non-standard dimensions
They diverge on capability: Packer covers Image building, Stable Diffusion covers Text-to-image.

Where each one falls short

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

Packer

Packer 1.10.0 and later is licensed under the Business Source License 1.1 with IBM Corporation as licensor, not an OSI open source licence
The Additional Use Grant forbids offering Packer to third parties on a hosted or embedded basis in a paid product that competes with IBM's paid versions of Packer
Each version converts to the MPL 2.0 Change License only four years after that version is first published, and the Change Date is set separately per version
Alternative licensing for uses outside the grant must be arranged with the licensor rather than taken under the public licence

Stable Diffusion

Generated images have lower resolution and quality at non-standard dimensions
Struggles with complex multi-object prompts and text generation
Poor rendering of human hands, limbs, and faces due to training data limitations
Trained primarily on English-language descriptions, reinforcing Western cultural bias
Requires significant GPU computational resources for local deployment

Answered from the vendors’ own pages

Stable Diffusion: Is Stable Diffusion truly free and open-source?

Yes. Stable Diffusion is released under the CreativeML Open RAIL-M license, allowing free use for both commercial and non-commercial purposes, and the code is open-source on GitHub.

Source

Stable Diffusion: Can I use Stable Diffusion commercially for free?

Yes, if your organization has less than $1M annual revenue. Organizations exceeding $1M annually must obtain an Enterprise License from Stability AI.

Source

Stable Diffusion: What are Stable Diffusion's image resolution limitations?

The base model was trained on 512x512 pixel images, and image quality degrades noticeably when deviating from this resolution. Newer models like SDXL support higher resolutions.

Source

Stable Diffusion: Can I run Stable Diffusion locally on my computer?

Yes. Stable Diffusion is open-source and can run locally on compatible hardware, though it requires a GPU for reasonable performance.
