# Introduction

> Open-source integration layer for agents and apps.

Corsair is an open-source integration layer for apps and agents. Connect to GitHub, Slack, Gmail, and 200+ other services through one syntax. Corsair handles OAuth, token refresh, webhooks, and rate limits.

You run it inside your own app. Credentials stay encrypted in your database. [Hub](/hub/overview) hosts connect pages and OAuth callbacks so you don't build those public URLs yourself.

Install plugins, wire up Corsair once, then call any integration the same way:

```ts corsair.ts theme={null}
import { createCorsair } from 'corsair';
import { github } from '@corsair-dev/github';
import { slack } from '@corsair-dev/slack';

export const corsair = createCorsair({
  plugins: [github(), slack()],
  database: db,
  kek: process.env.CORSAIR_KEK!,
  hub: {
    projectApiKey: process.env.CORSAIR_DEV_API_KEY!,
    signingSecret: process.env.CORSAIR_DEV_SIGNING_SECRET!,
  },
});
```

```ts route.ts theme={null}
await corsair.github.api.issues.create({ owner: 'acme', repo: 'app', title: 'Bug' });
await corsair.slack.api.messages.post({ channel: 'C123', text: 'On it.' });
```
