Cloudflare Flagship — OpenFeature-native feature flags with sub-ms edge evaluation
Cloudflare ships Flagship, an OpenFeature-compliant feature flag service built on Workers, Durable Objects, and KV. Sub-millisecond evaluation at the edge; closed beta. Designed so AI agents can safely deploy and ramp code behind flags.
Feature flags that evaluate in under a millisecond on Cloudflare Workers — so AI agents can roll out code behind flags without begging a third-party vendor.
What is it?
Flagship is Cloudflare's native feature flag service, announced April 17 at the end of Agents Week 2026 and currently in closed beta. It plugs in as an OpenFeature provider — OpenFeature is the CNCF open standard for feature flag evaluation — so teams already using LaunchDarkly, ConfigCat, or Unleash can adopt (or leave) Flagship by changing one line of configuration.
How does it work?
Writes are atomic against Durable Objects, which act as the source of truth. Reads fan out to Workers KV for global replication within seconds. Evaluation runs inside the same Cloudflare location that handles the incoming request, so there is no round-trip to an origin server — sub-millisecond p99 on Workers. It supports boolean, string, number, and JSON flag values, nested AND/OR targeting rules up to 5 levels deep, percentage rollouts via consistent hashing, and field-level audit trails. Works everywhere — Node.js, Bun, Deno, browser — but is fastest on Workers.
Why does it matter?
Feature flags are the standard 'safe-deploy' primitive for humans; for AI agents shipping code autonomously, they become load-bearing. Having the flag service co-located with the Worker that is being flagged eliminates the 'AI ships change, third-party flag provider is the bottleneck' failure mode. For teams already on Workers, this is a zero-latency, zero-extra-vendor option.
Who is it for?
Cloudflare Workers teams; platform engineers building agent-native deployment tooling.
