Caching and delivery innovations

Unlike CDNs built for the applications and internet of 20 years ago, Instart CDN is designed to accelerate modern websites and apps containing a mix of rich images, static content, and dynamic content. Create advanced caching logic for redirects, revalidations, serving stale from cache or even caching dynamic resources on the edge, greatly reducing round-trip times and improving time to first byte.

Automatic Performance Optimizations

As you update and add content to your site, Instart CDN continuously optimizes the delivery of assets by understanding how all resources are being consumed, and how your users interact with them. Never worry about breaking your pages or having to engage expensive FEO consultants.

The result is amazingly fast experiences for all users, especially those on mobile and WiFi connections.
