Buffer API Alternative

The developer-first alternative to the Buffer API

Buffer is an excellent tool for social media managers. Its API is not built for developers. No webhooks, no inbox API, no MCP server, and a queue-only posting model that gives you no real-time feedback on what happens after you submit. Aether is built for developers from the ground up.

What Buffer's API doesn't give developers

Buffer's developer API lets you add posts to a queue and retrieve profile data. That covers basic scheduling workflows — but developers building products need more.

  • No webhooks. Buffer has no webhook system. Once you add a post to the queue, you have no programmatic way to know when it publishes, if it fails, or what the platform-native post ID is. You would have to poll.
  • No inbox or DM API. Comments and direct messages are not accessible via Buffer's API. If you're building a customer service or engagement tool, Buffer's API doesn't cover it.
  • No MCP server. AI agent workflows that use Claude Desktop or Cursor cannot call Buffer as a tool. There is no MCP integration.
  • Queue-only model. Buffer's API is designed around its queue — not direct API publishing with programmatic control over exact publish times, retry logic, or failure handling.

The feature Buffer's API doesn't have: real-time webhooks

Buffer has no webhook system. With Aether, register once and your server is called the moment a post publishes, fails, or hits a rate limit — across all 7 platforms. This is what makes Aether suitable for building products, not just scheduling dashboards.

Node.js / TypeScript
import Aether from "aether";

const aether = new Aether({ apiKey: process.env.AETHER_API_KEY });

// Post to 3 platforms simultaneously — with real-time status via webhook
const post = await aether.posts.create({
  text: "Our new feature just shipped 🚀",
  profileIds: ["ig_abc123", "li_company789", "tt_xyz789"],
  mediaUrls: ["https://your-cdn.com/feature.mp4"],
  scheduledFor: "2026-06-15T09:00:00Z",
});
// → { id: "post_xyz", status: "scheduled" }

// Buffer has no webhook system — you never know when posts publish.
// With Aether, register once and get notified on every status change:
const webhook = await aether.webhooks.create({
  url: "https://yourapp.com/webhooks/social",
  events: ["post.published", "post.failed"],
});
Python
import os
import aether

client = aether.Aether(api_key=os.environ["AETHER_API_KEY"])

# Post to 3 platforms — scheduled, with webhook delivery on publish
post = client.posts.create(
    text="Our new feature just shipped 🚀",
    profile_ids=["ig_abc123", "li_company789", "tt_xyz789"],
    media_urls=["https://your-cdn.com/feature.mp4"],
    scheduled_for="2026-06-15T09:00:00Z",
)

# Register webhook — fires on post.published and post.failed
webhook = client.webhooks.create(
    url="https://yourapp.com/webhooks/social",
    events=["post.published", "post.failed"],
)
cURL
# Post to multiple platforms at once

How to switch from Buffer to Aether

Most Buffer API integrations can be migrated in under an hour.

  1. 1

    Get your Aether API key

    Sign up at aetherhq.dev — free tier includes 3 connected accounts and full API access including webhooks and inbox.

  2. 2

    Connect your social accounts

    Use Connect Links to authenticate each platform account. Your users click a URL, authorize on the platform, and the account appears in your dashboard. No OAuth credential management on your end.

  3. 3

    Replace Buffer queue calls with Aether posts

    Buffer: POST /1/updates/create with profile_ids and text. Aether: POST /v1/posts with profileIds, text, and scheduledFor. The main difference: Aether gives you direct control over publish timing and fires webhooks when done.

  4. 4

    Register a webhook

    POST /v1/webhooks with your endpoint URL and the events you care about (post.published, post.failed, post.scheduled). Buffer has no equivalent — this is the biggest capability unlock.

Frequently asked questions

Does Buffer have an API for developers?+

Yes, Buffer has a Publish API. It lets you add posts to a Buffer queue, get profiles, and retrieve scheduled posts. However, it's designed around Buffer's queue model — not direct API publishing — and it's missing key developer features: no webhooks, no inbox or DM access, no real-time post status callbacks, and no MCP server.

What's missing from the Buffer API compared to Aether?+

The biggest gaps are webhooks (Buffer has none — you can't know when a post publishes or fails without polling), inbox/DM management (not in the API at all), and MCP/AI agent support. Buffer is a social media scheduling tool with an API bolt-on. Aether is built API-first.

Can I post to Instagram with code using the Buffer API?+

You can add to a Buffer queue, but Buffer handles the actual publish — you don't control the exact publish time programmatically or get a webhook when it happens. With Aether, you call POST /v1/posts with a scheduledFor timestamp and Aether publishes at exactly that time, firing a webhook when it succeeds or fails.

How does Aether pricing compare to Buffer?+

Buffer charges per channel — $6/channel/month on Essentials. At 7 platforms across 3 brands, that's $126+/month before you get analytics or inbox features. Aether bundles everything (posting, scheduling, analytics, inbox, webhooks, MCP) and prices by usage, starting free.

How do I migrate from Buffer to Aether?+

Get an Aether API key (free), connect your social accounts via Connect Links, then replace your Buffer API calls with Aether's POST /v1/posts endpoint. The main code change is switching from 'add to queue' to 'post with scheduledFor' — and you gain webhooks, inbox, and MCP as you go.
