Both can post from code now. They’re still different things.
Buffer combines a calendar, drafts, an AI assistant and analytics. Its GraphQL API and hosted MCP server let applications and agents work with a connected Buffer account.
Social Fanout starts from the other end. Social Fanout stays API-first, while including a lightweight agenda as an optional reference client. Your software or agent can still do the posting directly. You connect each account once, then a single POST /v1/publish fans out to up to 20 targets and returns a receipt per target.1 The product is the API.
Compare the publishing request shape, account model, deployment terms and pricing. Social Fanout uses a targets array with per-target results and offers self-hosting or hosted white-label by written agreement; Buffer provides channel-based publishing within its app and API.

A calendar to drive, or a request to send
B BUFFER
- Open the app, pick a channel
- Draft the post, attach media
- Preview per network, adjust
- Schedule on the calendar — or use the GraphQL API per channel
SOCIAL FANOUT
Replace the example account IDs with your owned connections and keep the key private. This dry run checks routing and plan access without posting. It does not prove provider acceptance. Approve the exact content and accounts before a live request.
If a person is composing, Buffer’s calendar supports that workflow. If software composed it, you want the one request — fanned out, with a receipt for each target.
When Buffer fits
You want a finished product today — a content calendar, drafts, an AI assistant, and native analytics — and you’re happy for each user to bring their own Buffer account. Social Fanout includes a lightweight agenda and Post Flight Deck, but not a full campaign calendar, AI suite, or team workflow; it remains a building block first. Buffer’s team plans include collaboration and content approval workflows.
A team could use Buffer for campaign planning and Social Fanout for publishing within a product. Whether that combination helps depends on the existing workflow.
