Layer0 by Limelight

Dynamic websites that load in less than one second

Instant happens before the request

EdgeJS puts data into the browser 5 seconds before it’s needed

Simple, powerful workflow


Work with any framework. Run your edge logic locally. No vendor lock-in — hit the eject button whenever you want


In JavaScript We Trust. One single codebase is deployed to the browser, server, and for the first time ever, to the edge. Enjoy atomic deploys and rollbacks without ever having to guess what your edge/CDN is doing.


Every code push automatically gets its own live preview URL so QA, PMs, designers and other team members can preview the new feature on their devices and more easily discover regressions.


Blink-of-an-eye is hard work. Our network works hard before your customer taps to make sites load instantly.


Real-time Core Web Vitals, caching, and traffic monitoring at your fingertips. Displayed by route, release, and rendering—the way that matters to developers.


Split traffic at the edge to ensure that all your variations are instant including A/B split tests, canary deploys, and feature flags.


Defend your site against bad actors.

Why Layer0

Go instant

Instant websites, no excuses. The median Largest Contentful Paint of pages on the Layer0 network is 399ms, literally the blink of an eye. The sites have dynamic pricing, inventory and personalization and some even have numerous tags and slow APIs!

Ship fast

Developers love EdgeJS because it’s CDN config that they actually use. Makers collaborate better when every push to every branch gets its own preview URL. Teams improve faster when A/B tests can be trusted because they don’t slow down the website.

Go beyond static

Static site generation doesn’t work when you have 1000s of pages. Layer0 easily handles millions of pages while offering the speed of static websites.

Enhance your CDN

Try the world’s first JS-based CDN, one that you configure right within application code, and you’ll never go back to writing VCL, proprietary APIs, or trudging through a web console.

Go headless

Walk or run at your own pace into the architecture of tomorrow. Layer0 has everything you need to go headless and supports incrementally migrating traditional sites.

Deploy in minutes

Deploy your first site now for free in two minutes. Run your existing site at sub-second speeds in hours.

Scale in peace

Never worry about traffic spikes again. Layer0 shields over 95% of the traffic that goes to your content and catalog database and handles rendering and API aggregation at unlimited scale. 1/3 of Americans touch the Layer0 network each month.
