Chat SDK now has an adapter directory

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

These include:

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

• Vendor-official adapters: built and maintained by the platform companies, like Resend's email, Beeper Matrix, and Photon iMessage. These live in the vendor's 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 and made available to the community, 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.
