If you sell a course or a digital product on your own, social media is usually your cheapest marketing channel, and also one of the most tiring. The posts themselves aren’t the hard part. The hard part is remembering to publish them, by hand, on several accounts, at the times your audience is online, which tend to be exactly the times you’re in a meeting, on the school run or making dinner.

A scheduler fixes that: you write and load a batch of posts in one sitting, pick the dates, and the tool publishes them for you. This guide compares four schedulers on what a one-person business actually pays, and is honest about when you don’t need a paid one at all.

How this comparison was made: every price and limit below comes from each tool’s own pricing page, checked on 31 October 2026 (saved copies are kept with our records). Prices are in US dollars, as the pages show them, and may differ by country or exclude tax. We haven’t run the same posting calendar through all four, so this compares published plans, not a hands-on test.

The quick answer

  • Posting to one or two accounts? Start free. Buffer’s Free plan connects up to 3 channels, with 10 scheduled posts per channel at a time; Metricool’s Free plan schedules up to 20 posts a month for 1 brand.
  • Posting to around 5 accounts and want to batch a month at once? Postiz (affiliate link) Standard is US$29 a month, or US$23 a month billed yearly, for 5 connected accounts with unlimited posts. Buffer Essentials for 5 channels works out about the same (US$30 a month, or US$25 billed yearly).
  • Mostly Instagram, TikTok and Pinterest? Later Starter (US$25 a month, or US$18.75 billed yearly) covers one profile on each of its 8 networks, but caps you at 30 posts per profile per month.
  • Only Buffer and Metricool have a free plan. Postiz has a 7-day free trial; Buffer and Later have 14-day trials.

The problem: posting by hand doesn’t scale

Say you post three times a day on Instagram, LinkedIn and X. Done by hand, that’s nine separate posts a day, each needing you to stop what you’re doing, open the app, paste the text, attach the image and press publish at the right time. Miss a slot and the post either goes out late or not at all.

Batching solves it. You set aside one afternoon, write the month’s posts, load them into a scheduler with dates and times, and the tool handles the rest. The question is which scheduler fits a small budget and the number of accounts you run.

Checked on postiz.com/pricing, buffer.com/pricing, later.com/pricing and metricool.com/pricing on 31 October 2026. Buffer prices are per connected channel, so 5 channels on Essentials cost 5 × the figure shown. Compare Postiz at its pricing page (affiliate link).

Postiz

Postiz calls itself an “agentic” social media scheduler: alongside a normal calendar, every plan includes an API, a hosted MCP server and a command-line tool, so you can also have an AI assistant draft and schedule posts for you.

  • Standard: US$29 a month, or US$23 a month billed yearly. 5 channels, unlimited posts, an AI copilot, a picture editor, repeated posts, RSS auto-posting and analytics.
  • Team: US$39 a month (US$31 yearly). 10 channels and unlimited team members.
  • Pro: US$49 a month (US$39 yearly). 30 channels.
  • Ultimate: US$99 a month (US$79 yearly). 100 channels.

Postiz’s FAQ says there’s no free plan: “Postiz has a 7-day free trial on every plan, and paid plans start at $29 per month.” A “channel” is one connected social account, such as an X, LinkedIn, Instagram or Facebook account. Postiz’s network list is long and includes Bluesky, Threads, Mastodon, Reddit, Pinterest and YouTube as well as the big ones.

Good fit if you post to several networks (around 3 to 5 accounts) and want to load a whole month of posts at once without a per-post cap. Less good if you have one account: Buffer Essentials for one channel is US$5 or US$6 a month.

Postiz also says you can self-host it for free from its open-source code, but then you run the server and need each social network to approve your own app, which Postiz’s FAQ says can take weeks. For most solopreneurs the hosted plan is the realistic option.

Buffer

Buffer is one of the oldest schedulers and prices per channel, so you pay for exactly the accounts you connect.

  • Free: up to 3 channels, 10 scheduled posts per channel at a time (“refill anytime”), 1 user, AI assistant.
  • Essentials: US$6 per channel a month, or US$5 per channel a month billed yearly (US$60 per channel a year). Unlimited scheduled posts, advanced analytics, hashtag manager, first-comment scheduling.
  • Team: US$12 per channel a month, or US$10 billed yearly. Adds unlimited team members and access levels.

Paid plans have a 14-day free trial. Good fit if you have one to three accounts; the cost is low and the Free plan may be all you need. Watch the maths as you add accounts: at 5 channels Essentials is US$30 a month, level with Postiz Standard, and at 10 channels it’s US$60 a month.

Later

Later started as an Instagram planner and now covers Instagram, Facebook, TikTok, Threads, YouTube, Pinterest, LinkedIn and Snapchat. It prices by social set: one profile on each of those networks.

  • Starter: US$25 a month, or US$18.75 a month billed yearly. 1 social set (8 profiles), 1 user, up to 30 posts per profile, 3 months of analytics, link in bio.
  • Growth: US$50 a month, or US$37.50 billed yearly. 2 social sets, 2 users, collaboration and approvals.
  • Scale: US$110 a month, or US$82.50 billed yearly. 6 social sets, 4 users.

All three have a 14-day free trial. Later’s pricing page doesn’t list X (Twitter) among its networks. Good fit if you’re visual-first (Instagram, TikTok, Pinterest) and post up to about once a day per profile. Less good if you post several times a day: the 30-posts-per-profile cap on Starter runs out quickly.

Metricool

Metricool combines scheduling with analytics and competitor tracking, and prices by brand (one set of social accounts for one business).

  • Free: 1 brand, up to 20 scheduled posts a month, 30 days of analytics. Its pricing page says the free plan covers all networks except LinkedIn and Twitter.
  • Starter: from US$25 a month, or from US$20 a month billed yearly, for up to 5 brands (US$45 or US$36 for up to 10). Unlimited publishing, LinkedIn connection, PDF reports, analytics with unlimited history.
  • Advanced: from US$67 a month, or from US$53 billed yearly. Team, client and approval tools.

Metricool’s page marks unlimited publishing with an asterisk, and X (Twitter) is a separate add-on (US$10 a month per connected account). Good fit if you care about analytics as much as scheduling and don’t need X.

When a cheaper or free tool is enough

Many solopreneurs don’t need a paid scheduler yet. Stay free if:

  • You post to one to three accounts and batch a week at a time. Buffer Free (3 channels, 10 queued posts each) or Metricool Free (20 posts a month) will cover it.
  • You post a few times a week. Setting a reminder and posting by hand may genuinely be fine.

A paid tool earns its keep when you post to several networks, want to load a month at once without per-post caps, or want one calendar instead of four apps.

Scheduling TikTok: what to expect

TikTok handles scheduling differently from the other networks, and the answer depends on which route your tool uses. TikTok’s own desktop scheduler is the narrowest option: its help page puts desktop scheduling at a Business account or an account with 10,000 followers or more, and allows no more than 10 days ahead, so most creators schedule through a tool instead. Tools take one of two routes.

  • Direct posting. The video is published to your TikTok account at the time you set, with the privacy, comments, duet and stitch settings you chose in the tool. Postiz documents this mode for TikTok, and notes that TikTok requires the app to pass its Direct Post review before posts can be public rather than private.
  • Upload to your inbox (a draft). The video is not published. Postiz documents this mode too: the video lands in the TikTok app’s inbox and you finish and publish it by hand, and Postiz says to do that within 24 hours or it is discarded. Postiz also says TikTok ignores every setting except the title in this mode, so privacy and interaction options get decided in the app.
  • What you’ll see. With direct posting the video appears on your profile at the time you set. With the draft route it sits in the TikTok app’s inbox, where a notification asks you to finish the post, and nothing goes out until you publish it yourself. TikTok’s own desktop scheduler also sends a push notification when a scheduled post goes live.
  • Reach. TikTok’s help pages don’t say that scheduling, or posting through an approved app, changes how many people see a video, and we can’t confirm it either way. TikTok’s own explanation of how recommendations work lists user interactions, content information and user information as the factors, and doesn’t mention how a post was published. So “scheduling hurts reach” is unproven rather than established, in either direction.

One thing holds whichever route you use: connect the account from inside the tool, which takes you to TikTok’s own login and permission screen. TikTok says it doesn’t share your TikTok password with any third-party apps, and no scheduler should ask you for it.

Our verdict

For a course creator or solopreneur posting to several networks, Postiz Standard (affiliate link) at US$29 a month, or US$23 billed yearly, is a simple choice: 5 accounts, unlimited posts and a flat price, with a 7-day trial to check it fits your networks. Buffer is the better pick for one to three accounts (and free for light use), Later suits visual-first creators who post up to once a day, and Metricool suits people who want analytics alongside scheduling.

Whichever you choose, use the free trial or free plan with a real week of your own posts before paying for a year.

Quick answers

Is there a free social media scheduler for course creators? Yes. Buffer’s Free plan connects up to 3 channels with 10 scheduled posts per channel at a time, and Metricool’s Free plan schedules up to 20 posts a month for 1 brand (prices checked 31 October 2026).

Does Postiz have a free plan? No. Postiz has a 7-day free trial on every plan; its cheapest plan, Standard, is US$29 a month or US$23 a month billed yearly for 5 connected accounts.

Do scheduled TikTok posts go out on their own? Not always. Some tools publish straight to TikTok; others send the video to your TikTok inbox as a draft you finish and publish in the app. Postiz documents both (checked 5 November 2026).

Which is cheaper for 5 accounts, Postiz or Buffer? They’re about the same. Postiz Standard is US$29 a month (US$23 yearly); Buffer Essentials for 5 channels is US$30 a month (US$25 yearly).
