For n8n users, the best social media scheduler to automate is SchedPilot, because it ships custom n8n nodes and a REST API that the HTTP Request node can call directly, and it posts to nine networks from one endpoint. For Zapier and Make users who don’t want to touch an API, Publer, SocialBee and Metricool have the most complete native actions. Buffer works with all three builders but only for basic text and image posts.
The workflow that sends people looking for this is almost always the same: something happens (a GitHub release, a new blog post in the RSS feed, a row added to a Google Sheet, a Typeform submission) and a post should go out. Building that against each network’s own API is a week of work. Building it against a scheduler is an afternoon. (I compared the social media scheduling APIs worth building against in a separate post.)
1. SchedPilot (best for n8n)
SchedPilot has custom n8n nodes, so “new RSS item, post to X and LinkedIn at 9am” is three nodes with no code. If you’d rather use the generic HTTP node, the REST API is a single POST with content, date and time; it fans out to every connected account. An indie developer I know wired his release pipeline in one afternoon and it hasn’t dropped a post in months.
Beyond n8n, SchedPilot has an MCP server so Claude, ChatGPT or Cursor can act as the trigger instead of a workflow, and a CLI for cron-style scripts. Every automated post lands in the calendar for approval unless you turn that off, which is the safety net workflow tools generally lack. Nine networks: X, LinkedIn, Instagram, TikTok, Threads, Facebook, Pinterest, Bluesky, YouTube. API and n8n access are on the Platinum plan.
2. Publer
Publer’s Zapier and Make actions are among the more complete: create post, choose accounts, attach media, set a schedule. It’s the tool I’d point a non-developer at if they’re living in Zapier already and want video posting to work. No n8n node, but the Zapier action covers most cases.
3. SocialBee
SocialBee’s category-based queues pair well with automation: push content into a category and let the recycling schedule handle timing. Zapier and Make actions are solid. Better for evergreen content loops than for time-sensitive announcements.
4. Metricool
Metricool has Zapier and Make integrations plus an API on its Advanced plan. Strong if you want automation and analytics from the same product. The API is less documented than SchedPilot’s or Ayrshare’s, so expect some trial and error.
5. Ayrshare
Pure API, no native workflow-builder actions, but it’s easy to call from the HTTP nodes in n8n, Make or Zapier. Per-profile pricing. Good for developers, overkill for a marketer who wants a Zap.
6. Buffer
Buffer’s Zapier integration is the oldest on this list and the most limited. Text and a single image, add to queue. If that’s all you need, it’s fine. Video, first comments, threads and per-network customization aren’t available through automation.
7. Postiz
Open source with a public API and an MCP server; self-hosting it next to your n8n instance is a clean setup for teams that want everything on their own hardware. No native Zapier app, so it’s an HTTP-node tool.
Which builder, which tool
n8n users should go API-first: SchedPilot’s nodes or Postiz’s API, because n8n rewards tools that expose real endpoints. Make users get the most from Publer or Metricool’s native modules. Zapier users should watch task counts. A workflow posting to five accounts daily burns 150 tasks a month before you’ve added any logic, and at that point the scheduler subscription is cheaper than the Zapier bill.
One thing I’d push back on: automating publishing without an approval step. An RSS trigger will happily post your draft that leaked into the feed. Either use a scheduler with a review calendar or add a Slack approval step in the workflow. The rest of the automation stack, including the agent-based tools that are starting to replace some of these workflows, is in my post on the best AI automation tools.
