Cloudflare, a connectivity cloud and developer platform, launched Flagship into private beta, a native feature flag service built on its global network. Part of Agents Week, it uses Durable Objects and Workers KV for sub-millisecond evaluation. It is built on the OpenFeature CNCF standard for vendor-neutral integration.

As agentic coding tools ship features autonomously, the bottleneck shifts from writing code to safely releasing it. This follows Cloudflare's push to secure the agentic web by moving protection to the edge. Flagship eliminates latency by running evaluation logic in the same isolate handling the user request.
This extends efforts to improve agent readiness by providing infrastructure for machines to modify production environments safely. You can use Flagship to manage boolean or JSON flags with nested logical conditions. For Cloudflare Workers, a direct binding provides typed accessors without SDK overhead.
Still wondering? A few quick answers below.
Cloudflare Flagship is a native feature flag service that allows developers to toggle application features or configurations without redeploying code. It is built directly on Cloudflare's global network to provide sub-millisecond evaluation. By using feature flags, teams can safely release code and control the blast radius of new features, which is especially useful for autonomous AI agents.
Flagship uses Cloudflare's infrastructure, including Durable Objects for the control plane and Workers KV for global distribution. When a flag is updated, the change is synced to KV across the network. Evaluation happens at the edge in a lightweight isolate, which is a secure execution environment, matching the request context against targeting rules locally so no data is sent elsewhere.
Most third-party services require an outbound HTTP request to an external API, which adds latency to every user request. Flagship eliminates this by performing evaluations natively on Cloudflare's network. It also supports the OpenFeature standard, a vendor-neutral interface that prevents lock-in, and offers direct Worker bindings that allow for typed flag access without the overhead of an external SDK.
Cloudflare Flagship is currently in a private beta phase. Developers interested in using the service must request access through an official sign-up form on the Cloudflare website. While it is optimized for Cloudflare Workers, it also includes a client-side provider for browsers and supports other runtimes like Node.js, Bun, and Deno through the OpenFeature server-side SDK.
Flagship supports complex targeting rules using nested logical conditions like AND and OR, which can be nested up to five levels deep. Rules can include percentage-based rollouts that use consistent hashing to ensure users stay in their assigned bucket. This allows developers to gradually ramp up feature exposure from small test cohorts to the entire user base with confidence.
