Ship landing‑page blocks without waiting on engineering
Design, publish, and embed reusable web content blocks. Your marketing team updates live pages in seconds — no code changes, no CDN edits, no dev cycle.
From idea to embedded, in three steps
Design
Author a block with the VSCode extension or Claude. HTML + CSS, isolated and safe.
Publish
Push to staging, get it approved, promote to production — versioned and immutable.
Embed
A developer drops one tag. Marketing owns the content forever after.
<script src="https://cdn.cellpy.com/runtime.js"></script> <cellpy-block slug="homepage-hero"></cellpy-block>
Built like a developer tool. Run by marketing.
Shadow DOM isolation
Block styles never leak; host CSS never breaks the block.
Versioned URLs
Every publish is immutable. Roll forward without breaking embeds.
Edge CDN delivery
Served from Cloudflare in milliseconds, cached globally.
CSS variable theming
Match your brand with a few custom properties — no forking.
Update live pages without filing a ticket
Swap a hero, change a price, launch a campaign banner — all from a dashboard built for non-engineers. Changes go live in seconds across every page that embeds the block.
Author blocks side‑by‑side with Claude
Describe a block in plain language and Claude builds it — landing safely in your Workspace for review. Refine it conversationally, then publish when it's right.
