SSG (Static Site Generator)
GlossaryA tool that builds a static website from templates and data at build time.
Definition
A Static Site Generator (SSG) takes templates (Jinja, Nunjucks, Handlebars, JSX) and data (Markdown, JSON, CMS content) and produces a set of static HTML files at build time. Examples include Hugo (Go), Eleventy (JS), Jekyll (Ruby), Gatsby (React), and Astro (multi-framework). The output can be hosted anywhere that serves files.
Why it matters for form backends
SSG sites don't have a server runtime, so form handling requires an external hosted backend like FormLoom.
FAQ
An SSG only builds static files. A meta-framework like Next.js or SvelteKit can also run server code (SSR, Server Actions, API routes) at request time.
