Why we build on the edge
Edge runtimes changed how we deploy products: no servers to babysit, and a cold start measured in milliseconds.
Latency is a feature
Serving from the closest region turns a sluggish page into an instant one, and users feel it long before they can describe it.
Fewer moving parts
No VMs, no autoscaling groups, no patch windows. The deploy is a single upload, and a rollback is picking the previous version.
The trade-offs are real
Edge runtimes are not Node. Long-lived connections and native modules need rethinking — which is exactly the kind of constraint that keeps an architecture honest.
