Where Aether is meaningfully different
MCP server — first-class AI agent support
Aether ships a native MCP server. Every REST endpoint is exposed as an MCP tool — post creation, analytics, inbox management, webhook registration. Works with Claude Desktop, Cursor, and Windsurf out of the box. No competitor offers this yet.
Unified inbox API
DMs, comments, and mentions across Instagram, TikTok, LinkedIn, Facebook, YouTube, Threads, and Reddit in a single API. Read, reply, and mark threads as resolved programmatically. Built for customer support products and AI reply agents.
Threads and Reddit
Aether covers Threads (Meta) and Reddit — two platforms most social API providers still don't support. Threads has 300M+ users; Reddit is the highest-authority discussion platform for organic reach.
7-language SDKs from OpenAPI
Node.js, Python, Go, Java, Ruby, PHP, and .NET SDKs auto-generated from the OpenAPI spec. Every SDK is published to its native registry. The spec is publicly available for use with Postman, Insomnia, or custom code generators.
Usage-based pricing
Pay for what you use — no flat monthly minimum that you hit before shipping a single feature. The free tier is genuinely free: 3 accounts, full API access, webhooks, inbox, and analytics included.
Connect Links — zero-friction OAuth
Generate a URL per platform. Your users click it, authenticate on the platform's screen, and the profile appears immediately. You write zero OAuth code, store zero tokens, and handle zero token refresh logic.
Full 7-platform posting in one call
Post to every platform at once with per-platform overrides, then wire up webhooks for real-time delivery status:
import Aether from "aether";
const aether = new Aether({ apiKey: process.env.AETHER_API_KEY });
// Post to 7 platforms simultaneously
const post = await aether.posts.create({
text: "Shipping something new today 🚀",
profileIds: [
"ig_abc123", // Instagram
"tt_xyz789", // TikTok
"li_comp789", // LinkedIn
"fb_page456", // Facebook
"yt_ch123", // YouTube
"th_user456", // Threads
"rd_user789", // Reddit
],
scheduledFor: "2026-07-10T09:00:00Z",
});
// Set up a webhook to be notified when each platform publishes
const webhook = await aether.webhooks.create({
url: "https://your-app.com/hooks/aether",
events: ["post.published", "post.failed"],
