Buffer API Alternative
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.
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.
| Feature | Aether | Buffer API |
|---|---|---|
| Platforms | ✓Instagram, TikTok, LinkedIn, Facebook, YouTube, Threads, Reddit | ✗Instagram, Facebook, LinkedIn, TikTok, YouTube, Pinterest (no Threads, no Reddit) |
| Posting API | ✓Full REST — direct publish or schedule | ✗Queue-only — adds to Buffer queue, no direct publish control |
| Scheduling | ✓Native scheduledFor field, any timezone | ✗Via Buffer queue, limited timezone control |
| Analytics API | ✓Post + account metrics, custom date ranges | ✗Limited analytics — no full analytics API |
| Inbox / DMs | ✓Unified inbox API across all platforms | ✗Not available via API |
| Webhooks | ✓Real-time events for every post status change | ✗No webhooks — no real-time status delivery |
| MCP / AI agents | ✓Native MCP server — works with Claude, Cursor | ✗No MCP support |
| Free tier | ✓3 accounts, full API access | ✗3 channels (posting only, no inbox or webhooks) |
| Starting price | Free, then usage-based | $6/channel/month (Essentials plan) |
| Time to first post | < 15 minutes | < 15 minutes |
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.
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"],
});import os
import aether
client = aether.Aether(api_key=os.environ["AETHER_API_KEY"])
# Post to 3 platforms — scheduled, with webhook delivery on publish

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.
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.
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.
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.
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.
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.
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.
