Introduction

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 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:

corsair.ts

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!,
  },
});

route.ts

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