Unleash Enterprise Edge
Feature Flags at the speed of a CDN.
Unleash Enterprise Edge distributes feature flag evaluations closer to your users, reducing latency, increasing scalability and security - just like a CDN for your feature flags.
Key Benefits
Everything you need to run feature flags at the edge
Built for Enterprise-Scale Performance
Edge is a lightweight proxy layer between your Unleash API and SDKs, acting as a read replica to help you scale. It enables support for thousands of connected SDKs without increasing the load on your Unleash instance. Host Edge yourself, or let us host it for you.
Feature flag updates are instantly propagated across all Edge nodes, ensuring a consistent experience for users worldwide. Instead of relying on periodic polling, Edge uses a high-speed streaming protocol to sync flag changes in milliseconds. This means that when a new feature is rolled out, toggled off, or adjusted, every Edge node reflects the change in real time—without delays or stale data.
“With a single Unleash server and multiple Edge instances acting as a globally distributed read-only proxy, we can easily handle more than 20,000 RPS on a typical business day. Edge limits query load on the central server, keeps latency low, and keeps features running even if the server has hiccups. Even during Black Friday spikes, our feature flag system does not blink. Failures do not become outages.”
