Who is Cloudflare Workers best for?

Best use cases for Cloudflare Workers

• Applications that need globally distributed edge compute with sub-millisecond cold starts — Workers runs your code at the network edge close to users without the latency of routing to a regional data center.
• Teams building request manipulation logic (auth, routing, header transformation, A/B testing, geo-personalization) at the CDN layer rather than in application servers, eliminating a round-trip for every request.
• Developers building full-stack applications on Cloudflare's platform — Workers + R2 (object storage) + KV (key-value) + D1 (SQLite) + Durable Objects — who want a complete edge-native architecture without cloud vendor lock-in.

Who should avoid Cloudflare Workers?

• You need broad cloud-native triggers and deep integration breadth as the default
• Your functions need long-running execution or heavy compute per request
• You want maximum portability without platform-specific edge patterns

Upgrade triggers for Cloudflare Workers

• You need more complex state/queue orchestration and stronger operational ownership
• Runtime limits block required libraries or workloads
• You need tighter cost/egress modeling as traffic scales
