+
+# Clusters
+
+A **cluster** is a set of reverse proxies that serve your [Agent Network endpoint](/agent-network/how-it-works).
+Agents point at the endpoint hostname over the WireGuard tunnel; the proxy cluster terminates that
+traffic, enforces identity, policies, limits, and guardrails, and forwards each request to the
+upstream LLM API or gateway.
+
+Clusters run on **your own infrastructure**, so agent traffic terminates on machines you operate —
+giving you control over the data path, geographic placement, and TLS. Add **multiple proxies and clusters** to
+scale the environment: spread load across more proxy instances, place them closer to your agents or
+upstreams, and keep the endpoint available if one goes down.
+
+<Note>
+    Agent Network clusters are the same mechanism as Reverse Proxy clusters, scoped to your account
+    (**account clusters**). See [Bring Your Own Proxy](/manage/reverse-proxy/bring-your-own-proxy) for
+    the full cluster model.
+</Note>
+
+## Manage Clusters
+
+Go to **Agent Network → Configuration → Clusters** to see every cluster serving your account, along
+with the number of connected proxies, online status, and the capabilities each proxy reports.

+
+Use **Setup Self-Hosted Cluster** to register a new one. Enter a domain for the cluster and pick a
+**Deployment Method**: run it yourself with Docker, or use one of the **1-click deployments** for
+popular cloud providers to stand up a proxy in a few clicks. The wizard then walks you through the
+DNS records to add and starting the proxy.
