Agent access
Buffer's MCP server lets an assistant read channels, browse the queue, schedule posts and pull analytics. SocialHandoff exposes tools such as draft_post, schedule_post and preview_posts, but approve_post works only with owner keys. The design goal is that no agent can push content live on its own until you promote it.
Approval and safety
Buffer's Team plan lets you manage who can draft and who can approve. SocialHandoff makes approval the default path for agents and adds guardrails (banned topics, length per network, missing alt text, daily limits), a kill switch and a hash-chained audit log.
Networks and analytics
Buffer still leads here. It supports YouTube, Pinterest and more alongside Instagram, TikTok and Facebook, with analytics across them. SocialHandoff now covers Instagram (professional accounts), Facebook Pages and TikTok too, but not YouTube or Pinterest, and it reports per-post metrics where the network returns them.
Pricing arithmetic
Buffer's published Essentials price is $5 per channel per month. Five channels come to $25/month, or $50/month on the Team plan at $10 per channel. SocialHandoff Starter is $19/month for 5 channels and 2 agents, and self-hosting is free. This compares cost only, not scope: Buffer covers more networks and includes a free tier.
Migration notes
There is no direct Buffer importer. Connect your accounts in SocialHandoff, then point your agent at the MCP server. Some teams keep Buffer for YouTube and Pinterest and route agent drafts for every other network through SocialHandoff. Start with getting started.
Who should pick which
A solo creator posting to Pinterest, YouTube and LinkedIn by hand will likely be happier with Buffer's free plan. A developer-tools company whose release bot and marketing agent both draft for X, Bluesky and Mastodon will get more from SocialHandoff's scoped keys and approval inbox. Teams in between can run both, since the tools do not conflict.
