18 Platforms for What Price? A 2026 Social Scheduler Breadth Study

A lower scheduler price can buy fewer networks. The useful comparison is price against the roster you actually need, not a headline plan alone. This study pairs listed platform coverage with five-account and ten-account monthly prices. Research notes: 15 September 2026. Re-open every source before publish. Platform count is not a quality score.

The short answer

Full plan detail sits on pricing and MCP. This page owns breadth versus price. Broad "who is cheapest" intent stays on cheapest social media scheduler 2026.

How we counted

• Count a named integration once, using the vendor's own published list.
• Record whether it is a network, publishing destination, business profile, messaging destination, or content platform.
• Keep listed separate from live capability, post-type support, plan availability, and regional availability.
• Use monthly public list prices. Keep USD and EUR as published.
• Show base and agent-enabled prices only where MCP is known. Do not invent a fee.
• Do not treat price divided by platform count as a universal value score.
• SociaHive appears as automation-led category context, not a like-for-like cheap scheduler.

Verify-before-publish: re-open pricing, integrations, and MCP pages; confirm Posterly's 18 and PostEverywhere's approximately 11 with a dated register; confirm Buffer $5 / $10 per channel; confirm plan access for named networks; use "about" where the source is not exact.

Platform register (dated snapshot)

Auditable register from the 15 September 2026 research snapshot. Re-open every source URL before publish. Listed coverage is not a quality score.

Note: listed coverage is not a quality score. Posterly totals 18 named platforms; PostEverywhere is recorded at about 11 (the eleven networks above from the mcp-competitors brief). Re-verify names, plan access, and publishing capability on live pages before publish. SociaHive notes record about nine scheduling platforms (verify). SocialMate Free notes record seven live platforms with Meta surfaces still on the roadmap in older write-ups (verify).

Price at five and ten accounts

Listed platform coverage and monthly roster price

All rows verify-before-publish.

Safe quote (verify before publishing): The September 2026 snapshot listed 18 Posterly platforms and about 11 PostEverywhere platforms. At five accounts, recorded totals were $10 with MCP for Posterly and $19 for PostEverywhere with MCP included.

Where breadth matters

Use the register as a checklist, not a trophy count.

• Major networks: Instagram, TikTok, LinkedIn, Facebook, YouTube, X, Threads, Pinterest, Bluesky.
• Local and business: Google Business Profile when local listings are required.
• Messaging and community: Telegram, Discord, Slack, Mastodon, Lemmy.
• Publisher destinations: Dev.to, Hashnode, WordPress.

If your roster is mostly Instagram and TikTok, eighteen destinations may not matter. If you need GBP plus Slack plus a publisher network, a shorter list can force a second tool. Compare PostEverywhere vs Posterly and Buffer vs Posterly for product trade-offs. Larger suite exits often start from a Hootsuite alternative or Later alternative path.

MCP treatment interacts with breadth: Posterly's agent access is a +$3 add-on on Starter and Pro; PostEverywhere lists MCP as included. That pricing question is owned in detail by the MCP pricing study. Agency capacity maths lives on the agency seat and client cost study.
