Cheapest social media scheduler in 2026: real all-in cost at 5 and 10 accounts

"From $5" means almost nothing until you know how many profiles you connect, whether X or LinkedIn is an add-on, and whether API or MCP access is included. This guide prices the tools people actually compare when they search for the cheapest social media scheduler in 2026, using public vendor pages as of 15 September 2026.

We show all-in monthly cost at 5 and 10 connected accounts, including Posterly's optional API & MCP add-on when you want agents. Posterly does not offer Autopilot.

What "cheapest" should mean in 2026

Searchers who type cheapest social media scheduler or Buffer alternative cheap usually manage about five to ten profiles. They are freelancers, creators, and small businesses. They are not buying enterprise suites.

Three traps distort the headline:

1. One-channel teaser pricing. Buffer Essentials is $5 per channel per month. One channel is $5. Five channels are $25. Ten are $50.
2. Free plans with hard caps. Buffer Free, Metricool Free, Publer Free, and SocialMate Free exist, but pending posts, missing networks, or schedule windows make them awkward for daily posting across a real roster.
3. Hidden MCP or API line items. Some tools include MCP on every plan (Schedulin, PostEverywhere). Others gate API to higher tiers. Posterly keeps scheduling cheap and sells MCP as a clear add-on (+$3 on Starter and Pro).

All-in at a realistic account count is the useful number. Headline "from" prices are not.

Quick verdict

Posterly is not always the rock-bottom headline. It wins on an honest flat bill at five to ten accounts, 18 platforms, and an optional MCP server without forcing you onto an automation suite.

All-in cost comparison table

Monthly USD unless noted. Prices as of 15 Sep 2026. MCP/API column is "included in that row's price" unless noted.

Posterly all-in callouts (required):

• 5 accounts, scheduling only: $7/mo (Starter)
• 5 accounts + MCP: $10/mo ($7 + $3)
• 10 accounts, scheduling only: $15/mo (Pro covers 12)
• 10 accounts + MCP: $18/mo ($15 + $3)

Full plan ladder and the account slider live on posterly pricing from $7/mo. Agency is $49/mo for 100 accounts (10 seats, 30 client groups). Power is $25/mo for 30 accounts. MCP add-on is +$3 Starter/Pro, +$5 Power, +$29 Agency.

Per-channel vs flat pricing

Buffer maths (live $5 / $10, not $6 / $12)

Buffer's public pricing (Sep 2026) lists Essentials at $5 per channel per month and Team at $10 per channel per month. Worked examples:

• 5 channels Essentials = $25/mo
• 10 channels Essentials = $50/mo
• 5 channels Team = $50/mo
• 10 channels Team = $100/mo

Some third-party round-ups and even older Posterly template copy on /vs/buffer still quote $6 / $12. Treat those as stale. Live Buffer is $5 / $10. Free Buffer still exists with 10 scheduled posts per channel and limited channels. A 14-day trial covers paid plans.

If you outgrew Buffer's per-channel bill, Buffer vs posterly walks the feature trade-offs. For larger legacy stacks, a Hootsuite alternative comparison is the other common path. Creators leaving visual-first planners often compare a Later alternative next.

Publer calculator quirks

Publer prices per social account. Professional starts around $5 for the first account; Business around $10. Every 10th account is free. Calculator bands commonly land near ~$20 at 5 accounts and ~$36 at 10 on Professional, and ~$35 / ~$63 on Business. Help-centre formulas can differ slightly from the calculator once you pass three accounts. AI, deeper analytics, and API lean Business and up. MCP is described as beta or limited in third-party write-ups; verify on Publer's docs before you buy for agents.

Flat plans (Posterly, Schedulin, Schedchie, SocialBee bands) are easier to forecast. Per-channel and per-account models punish growth even when the "from" price looked friendly.

Free and near-free options

Free plans are fine for testing OAuth and a light queue. They are rarely enough for daily posting across five to ten profiles. Near-free SocialMate Pro at $8 is compelling on price, but the missing Meta surfaces are a real caveat for "cheapest scheduler" shoppers who need Instagram.

Schedchie has no free tier; Pro is €7.99/mo flat with a 14-day trial. Posterly has a 7-day free trial and no permanent free plan.

MCP and API: the hidden line item

Agent workflows (Claude, ChatGPT, Cursor) turned MCP into a pricing feature, not a footnote.

If your buying criterion is "cheapest tool that already includes MCP," Schedulin's $5 Starter is the aggressive peer. If you want more platforms and a deeper scheduling tool surface, Posterly at $10 all-in (5 accounts + MCP) or $18 (10 accounts + MCP) is usually cheaper than PostEverywhere's Starter $19 / Growth $29 at those counts, while PostEverywhere includes MCP with no add-on line.

Posterly does not claim Autopilot, Auto-Publisher, or set-and-forget publishing of everything. MCP is for agents that schedule, upload media, and read analytics within plan limits.

Feature trade-offs that still matter

Price is not the only line.

Platforms. Posterly lists 18, including Google Business Profile, Mastodon, Slack, WordPress, Dev.to, Hashnode, Lemmy, and the usual Instagram, TikTok, LinkedIn, Facebook, YouTube, X, Threads, Pinterest, Bluesky set. SocialMate's live set is thinner until Meta ships. PostEverywhere markets 11. Schedulin competes on price and MCP, not on matching every niche network.

AI credits and post caps. SocialBee and Metricool lean into analytics and content systems at higher bands. Posthive Creator caps posts (400/mo). Buffer Essentials markets unlimited scheduled posts per channel once you pay per channel.

GBP and local. If Google Business Profile is on your roster, confirm it before you buy a "cheap" tool that never listed it. Posterly includes GBP in the 18.

Team seats. Buffer Team multiplies per channel. Posterly Agency adds seats and client groups at $49. SocialBee and Metricool scale by profile or brand bands.

No Autopilot on Posterly. If you need Instagram comment-to-DM automation suites, that is a different product category (for example SociaHive), not a scheduling price war.

When Posterly is the better buy

Choose Posterly when you want:

• Flat $7 for five accounts or $15 for up to twelve, without per-channel multiplication
• Optional agents at +$3 on those tiers (posterly MCP server)
• 18 platforms including GBP and several publisher/community networks
• A clean trial path: start a 7-day free trial

Skip the "always cheapest" claim. Schedulin can undercut on a three-account MCP-included Starter. Schedchie can undercut on a flat euro unlimited plan. SocialMate can undercut if your networks are already live there. Posterly's pitch is honest all-in at five to ten accounts, platform breadth, and optional MCP, not a forever race to $5 for one channel.

Power ($25 / 30 accounts) and Agency ($49 / 100 accounts) sit above this "cheap scheduler" search results band but matter once you outgrow Pro.

How to switch without drama

1. Drain the old queue. Let Buffer or Publer posts publish or pause them deliberately. Do not leave two tools racing the same slot.
2. Reconnect with OAuth on Posterly for each network. Expect Instagram and LinkedIn to ask for business/creator assets.
3. Rebuild the next two weeks only. Prove timezone, first comment, and media rules before you migrate a quarter of content.
4. Add MCP after the paid plan is live if you need agents. The add-on is not on the free trial as a substitute for a plan; follow get-started on /mcp.
5. Start a 7-day free trial on Starter if five accounts cover you, or jump to Pro if you already know you need about ten.

Leaving Hootsuite-class suites or Later-style visual planners follows the same pattern: finish the old calendar, reconnect, then expand. Use the Hootsuite alternative and Later alternative pages when those are your exit points.

CTA

Start a 7-day free trial on Starter ($7/mo for 5 accounts) or Pro if you need about ten profiles: start a 7-day free trial.

If you already know you want agents, review the posterly MCP server and enable the API & MCP add-on after a paid plan is active. Compare Buffer, Publer, and other exits from Buffer vs posterly, Publer vs posterly, a Hootsuite alternative, or a Later alternative. Full numbers stay on posterly pricing from $7/mo.
