Connecting to production: the architecture of remote bindings

Cloudflare introduces general availability of remote bindings for Workers, enabling local development to connect to deployed resources like KV, R2, and D1 by adding remote:true per binding in Wrangler config. The feature reuses production service-binding semantics—translating binding calls in the local workerd to HTTP or JSRPC over Cap’n Web WebSockets—to provide seamless access to real data without deploying on each iteration, unifying prior ad hoc approaches (e.g., AI binding). Support extends beyond wrangler dev to the Cloudflare Vite plugin and vitest-pool-workers via exported utilities such as startRemoteProxySession.
