RPC runs over HTTP, WebSocket, and message ports. Pick the adapter for your transport, then import [RPC Handler](/docs/rpc/handler) or [RPC Link](/docs/rpc/link) from it. The router stays the same.

## Server Adapters

| Adapter                                     | Import `RPCHandler` from                                                         |
| ------------------------------------------- | -------------------------------------------------------------------------------- |
| [Fetch API](/docs/adapters/fetch-api)       | `@orpc/server/fetch`                                                             |
| [Node HTTP](/docs/adapters/node-http)       | `@orpc/server/node`                                                              |
| [Fastify](/docs/adapters/fastify)           | `@orpc/server/fastify`                                                           |
| [AWS Lambda](/docs/adapters/aws-lambda)     | `@orpc/server/aws-lambda`                                                        |
| [WebSocket](/docs/adapters/websocket)       | `@orpc/server/websocket`, or `@orpc/server/crossws` as `experimental_RPCHandler` |
| [Message Port](/docs/adapters/message-port) | `@orpc/server/message-port`                                                      |

## Client Adapters

| Adapter                                     | Import `RPCLink` from       | Calls                     |
| ------------------------------------------- | --------------------------- | ------------------------- |
| [Fetch API](/docs/adapters/fetch-api)       | `@orpc/client/fetch`        | Any HTTP server adapter   |
| [WebSocket](/docs/adapters/websocket)       | `@orpc/client/websocket`    | WebSocket server adapters |
| [Message Port](/docs/adapters/message-port) | `@orpc/client/message-port` | Message Port adapter      |

## Frameworks and Platforms

Framework and platform adapters build on the ones above, such as [Next.js](/docs/adapters/next) and [Hono](/docs/adapters/hono) on the Fetch API, [Express.js](/docs/adapters/express) on Node HTTP, and [Electron](/docs/adapters/electron) and [Web Workers](/docs/adapters/web-workers) on Message Port. See [Adapters](/docs/adapters) for the full list.
