Your Multi-CDN Strategy.
Fully Automated.

Automatic traffic steering across multiple CDNs —
one dashboard, less downtime, same bits at a cheaper price.

The CDN+ Advantage
Multi-CDN redundancy without the complexity

Best Pricing

Access discounted capacity rates typically reserved for large-volume buyers, and route traffic to regional CDN specialists in underserved markets — so you get the best per-GB price in every geography without negotiating your own contracts.

Configurable Switchover

Define your own routing rules across any number of CDN providers. Set priority orders, weighted splits, and geo-specific policies — traffic follows your playbook automatically.

One Click Migration

No code changes, no re-integration, no downtime. Your current CDN stays as primary while CDN+ layers in cost optimization, performance routing, and automatic failover on top. One dashboard, zero migration headaches.

Smart Switchover
Always on the best CDN — automatically

CDN+ continuously evaluates your providers and switches traffic in real time — not just when something breaks, but whenever a better option exists based on performance, pricing, or your geographic traffic policies.

  • Switches on degradation — move traffic off unhealthy CDNs in seconds
  • Switches on performance — route to the lowest-latency provider per region
  • Switches on pricing — shift traffic to the cheapest provider in each geography
  • Geo-aware policies — different rules for different regions, all automatic
