Content stability should determine static generation

Blogs and documentation usually change when authors publish, rather than separately for every reader.

Their shared content can therefore be rendered before deployment with predictable and reviewable results.

Jekyll combines markup with layouts into a static website that can be deployed as files.

Eleventy and Hugo follow this broad model while offering different languages, pipelines, and conventions.

Static generation fits routes sharing content across users when freshness can reasonably follow each build.

Personalization, private data, volatile inventories, and request-specific authorization weaken that architectural fit considerably.

If route-specific rendering frames architectural decisions, build-time generation supplies one practical option.

Choose SSGs from content behavior because no generator removes freshness, personalization, or interaction requirements.
