An adapter connects a handler to where your code runs. The router stays the same, so switching hosts only changes the few lines that mount the handler. HTTP adapters serve both the [RPC Handler](/docs/rpc/handler) and the [OpenAPI Handler](/docs/openapi/handler).

## Core

- [Fetch API](/docs/adapters/fetch-api): Bun, Deno, and anything built on `Request` and `Response`.
- [Node HTTP](/docs/adapters/node-http): Node's `http`, `https`, and `http2` servers.
- [Fastify](/docs/adapters/fastify): Fastify servers.
- [AWS Lambda](/docs/adapters/aws-lambda): API Gateway and Function URLs, with response streaming.
- [WebSocket](/docs/adapters/websocket): ws, crossws, Bun, Deno, Cloudflare, and uWebSockets.
- [Message Port](/docs/adapters/message-port): iframes, workers, and other contexts linked by a `MessagePort`.

## Frameworks

Built on the Fetch API: [Next.js](/docs/adapters/next), [Nuxt](/docs/adapters/nuxt), [SvelteKit](/docs/adapters/svelte-kit), [TanStack Start](/docs/adapters/tanstack-start), [SolidStart](/docs/adapters/solid-start), [React Router](/docs/adapters/react-router), [Astro](/docs/adapters/astro), [Hono](/docs/adapters/hono), [Elysia](/docs/adapters/elysia), and [H3](/docs/adapters/h3). Built on Node HTTP: [Express.js](/docs/adapters/express).

## Platforms

- [Cloudflare Workers](/docs/adapters/cloudflare-workers): the Fetch API Adapter plus the compatibility flags it needs.
- [Expo](/docs/adapters/expo): call oRPC from a React Native app.

## Between Contexts

Built on the Message Port Adapter: [Browser](/docs/adapters/browser) (extensions and windows), [Electron](/docs/adapters/electron), [Web Workers](/docs/adapters/web-workers), and [Worker Threads](/docs/adapters/worker-threads).
