01
Isolate-based cold starts
V8 isolates start in milliseconds, without container or microVM boot delays.

Cloudflare Workers, Pages & edge computing
We deploy edge services and global routing layers on Cloudflare Workers, running code in the data center closest to each user.
Core capabilities
Why we build with Cloudflare Workers
02
Durable Objects & edge coordination
Strongly consistent distributed state and real-time collaboration at global edge points.
03
Edge security & bot management
Custom WAF rules, rate limiters and payload verification before requests ever reach origin servers.
Use cases
Where Cloudflare Workers fits
Edge A/B testing & routing
Rewriting HTML and routing traffic at the edge, so experiments do not cause client-side layout shift.
Authentication proxies at the edge
Verifying JWTs and session tokens at edge locations before requests reach origin backends.
How we staff it
Cloudflare Workers engineers you interview first
Seniority and experience are agreed in the proposal, and you interview every engineer before they start.
Working-hours overlap is agreed for each engagement and written into the statement of work — the shared window, who shifts hours, and how handoffs work outside it.
Technical FAQs
Frequently asked engineering questions
Workers run in V8 isolates across Cloudflare's global network, so cold starts are negligible and code runs near each user. Lambda runs in Firecracker microVMs in the AWS regions you choose, with a wider choice of runtimes and deeper AWS integration.
Yes, using Workers KV for cached reads, D1 for serverless SQL, Hyperdrive for Postgres acceleration, or Durable Objects for consistent state.
