Social SDK is an open-source TypeScript toolkit for solo founders and small teams adding social features to their apps. Publish, read, and access analytics or comments where available across X, Threads, Bluesky, YouTube, TikTok, Instagram, and LinkedIn through a typed interface.

Choose direct platform access or a managed backend: Zernio, Post for Me, PostFast, Postiz, or Buffer.

Start with the quickstart · Install from npm

• Direct adapters for Bluesky, Instagram, LinkedIn, Threads, TikTok, X, and YouTube
• Optional managed backends for Zernio, Post for Me, PostFast, Postiz, and Buffer
• Typed capability manifests and platform-native operations behind explicit subpath imports
• Independent per-destination outcomes for complete, processing, uncertain, and failed work
• A deterministic mock backend for local development and contract tests
• A CLI for adapter discovery, capability checks, diagnostics, and request validation that never contacts a social platform

Social SDK runs in trusted server-side code on Node.js 22.12+ or Bun. Keep platform tokens, managed-provider keys, OAuth secrets, and webhook secrets out of browser bundles.

npm install @opencoredev/social-sdk
# or
bun add @opencoredev/social-sdk

For application setup and integration options, see the installation guide.

Start with the mock backend to verify an integration without credentials, platform calls, or billable provider requests:

import { createSocial, connectedAccountRef } from "@opencoredev/social-sdk";
import { mockBackend } from "@opencoredev/social-sdk/testing";

const social = createSocial({
  backend: mockBackend({ scenario: "immediate-text-success" }),
});

const result = await social.posts.publish({
  targets: [
    {
      account: connectedAccountRef({
        backend: "default",
        platform: "x",
        accountId: "mock-account-1",
      }),
    },
  ],
  content: { text: "Hello from Social SDK" },
  idempotencyKey: "quickstart-1",
});

console.log(result.status, result.outcomes[0]?.state);
// complete published

The same client shape works with a direct platform adapter or a managed backend. Import only the adapter you use from its documented subpath.

Direct platform adapters cover Bluesky, Instagram, LinkedIn, Threads, TikTok, X, and YouTube. Hosted execution routes are available through the Zernio, Post for Me, PostFast, Postiz, and Buffer adapters. Managed services are optional; a direct integration does not require a Social SDK account.

Read the platform capability matrix before choosing an adapter. It describes the normalized operations implemented by each integration and does not replace provider permissions, account eligibility, or live verification.

The social-sdk CLI never contacts a social platform. It does not authenticate accounts, upload media, or publish content. It sends one anonymous usage event per command (command, adapter, SDK version, runtime and OS) after a one-time notice; turn that off with social-sdk telemetry disable, SOCIAL_SDK_TELEMETRY_DISABLED=1 or DO_NOT_TRACK=1. It is always off in CI. See CLI telemetry. The SDK library sends no telemetry.

The package installs the binary into your project's node_modules/.bin, which is not on your shell PATH. After installing @opencoredev/social-sdk, run it from that project directory with npm exec, or replace npm exec -- with bun run under Bun:

npm exec -- social-sdk adapters --json
npm exec -- social-sdk capabilities --adapter youtube --json
npm exec -- social-sdk doctor --adapter zernio --json
npm exec -- social-sdk examples --json
npm exec -- social-sdk validate --adapter mock --file request.json --json

See the CLI reference for command output, validation limits, and exit codes.
