SDK & API
IncludedAny framework. Your components. One API.
SpaceBlock is headless: the site keeps its own code and design. A small JavaScript SDK marks which elements are editable and powers the visual editor on the live site; content is fetched as JSON from the public API, with ETags and CDN caching so pages stay fast. Publish purges the cache through signed webhooks, so what is live is always what was last published.
WHAT YOU GET
Works with your stack
React, Next.js, Vue, Astro or vanilla HTML — anything that can call an HTTP API.
Mark-up, not rewrite
Add data attributes to the elements that should be editable; the SDK handles the rest.
Public JSON API
Pages, blocks, posts, collections and media as JSON, keyed by a per-project API key.
Fast by default
CDN caching with ETags, purged the instant content changes through signed webhooks.
Render endpoint
Server-side meta tags, real 404s and crawlable text for single-page apps, without a rewrite.
Figma to blocks
Import frames from Figma as block templates and mount them on the site.
WHO IT’S FOR
For developers handing a site to a client. It replaces the choice between a theme-locked CMS and building an admin from scratch.
