How to Load Balance Cloudflare Workers in 2026
A complete guide to load balancing Cloudflare Workers. Distribute traffic across multiple origins with health checks, failover, and zero downtime.
What is Cloudflare Workers Load Balancing?
Cloudflare Workers run at the edge — on 330+ data centers worldwide. When you load balance with Workers, traffic routing happens at the edge, not at a centralized load balancer. Lower latency, no single point of failure, automatic global distribution.
Traditional load balancers (AWS ALB, Nginx, HAProxy) sit between your users and your servers. Workers-based load balancing replaces that with a lightweight script that runs at every Cloudflare data center.
Why Workers Instead of Traditional Load Balancers?
Cost: AWS ALB costs ~$22/month before any traffic. Workers cost $0 under 100k requests/day.
Latency: Traditional LBs add 5-20ms. Workers add ~1-3ms (edge-level routing).
Global distribution: Traditional LB serves from one region. Workers serve from the closest data center automatically.
No idle fees: AWS charges by the hour even at zero traffic. Workers charge per request only.
Deploy a Load Balancer
1. Connect your Cloudflare account via OAuth or API token
2. Choose a routing strategy (round robin, weighted, IP hash, sticky, failover, geo)
3. Add your origin server URLs
4. Click deploy — live in ~90 seconds
Health Checks
EdgeBalancer runs periodic health checks to each origin. If an origin returns 5xx, times out, or refuses connections, it's removed from rotation. When it recovers, traffic resumes. Intervals are configurable from 10 seconds to 5 minutes.
What if EdgeBalancer Goes Down?
Nothing. Your load balancers keep running. EdgeBalancer is only the control plane — the load balancer runs in your Cloudflare account.
