  title: LaunchDarkly Relay Proxy Access Tokens Metrics API
  description: The LaunchDarkly Relay Proxy is a small Go application that connects to the LaunchDarkly streaming API and proxies that connection to SDK clients within an organization's network. It exposes endpoints for status monitoring, flag evaluation, and SDK streaming that mirror the LaunchDarkly service endpoints. Instead of each server making outbound connections to LaunchDarkly's streaming service, multiple servers connect to the local Relay Proxy which maintains a single upstream connection.
