Deployless – Ship site announcements instantly without redeploys

Summary: Deployless enables engineering teams to deliver runtime UI elements like banners, popups, and toasts in under 150ms without modifying code or redeploying. It decouples dynamic site announcements from application logic using a dashboard and edge-based evaluation for fast, isolated delivery.

What it does

Deployless uses a Runtime Content Delivery Network (RCDN) to separate ephemeral UI from core deployments. It evaluates targeting rules at the edge via Cloudflare Workers and loads only necessary rendering code with a minimal initial script (~2KB), ensuring fast and isolated UI updates.

Who it's for

It is designed for engineering teams needing to update live site announcements quickly without impacting application performance or layout integrity.

Why it matters

Deployless solves the problem of slow, heavy announcement tools that break site styles by providing a fast, lightweight, and CSS-isolated solution that avoids redeploys and large JS bundles.
