Chat SDK now has an adapter directory

Chat SDK now has an adapter directory, so you can search platform and state adapters from Vercel and the community.

These include:

• Official adapters: maintained by the core Chat SDK team and published under @chat-adapter/*

• Vendor-official adapters: built and maintained by the platform companies, like Resend and Beeper. These live in their GitHub org and are documented in their docs.

• Community adapters are built by third-party developers, and can be published by one, following the same model as AI SDK community providers.

We encourage teams to build and submit adapters to be included in this new directory, like Resend's adapter that connects email to Chat SDK:

1
import { Chat } from "chat";
2
import { MemoryStateAdapter } from "@chat-adapter/state-memory";
3
import { createResendAdapter } from "@resend/chat-sdk-adapter";
4

5
const resend = createResendAdapter({
6
  fromAddress: "bot@yourdomain.com",
7
});
8

9
const chat = new Chat({
10
  userName: "email-bot",
11
  adapters: { resend },
12
  state: new MemoryStateAdapter(),
13
});
14

15
// New inbound email (new thread)
16
chat.onNewMention(async (thread, message) => {
17
  await thread.subscribe();
18
  await thread.post(`Got your email: ${message.text}`);
19
});

Browse the adapter directory or read the contributing guide to learn how to build, test, document, and publish your own adapter.
