Key takeaways
- Buffer's free plan is still the most balanced: 3 channels, 10 queued posts per channel, and an AI assistant with unlimited credits, but there's a hidden lifetime cap of 8 channel connections ever.
- Metricool's free tier caps you at 20 published posts a month across one brand, and it quietly blocks LinkedIn and X entirely unless you pay.
- Planable's free plan is generous in an unusual way: unlimited workspaces and users, but only 50 posts total for the life of the account, not per month.
- Meta Business Suite is the only truly unlimited free scheduler, but it only covers Facebook and Instagram and can't schedule more than about 30 days out.
- Publer gives you 3 accounts and 10 queued posts each, but deletes your published post history after 24 hours, so don't expect to use it for reporting.
Why "free" doesn't mean the same thing twice
Every vendor in this space uses the word "free" to mean something slightly different, and that's not an accident. Some cap you by post count, some by month, some by lifetime total, some by number of connected accounts. If you don't read the fine print you'll hit a wall mid-campaign and have no idea why.
I went through the actual pricing and help-center pages for the tools people mention most when this topic comes up, rather than trusting marketing pages that love to say "free forever" without saying free for what, exactly. Here's what's really on offer in 2026, and where each tool quietly draws the line.
Quick comparison: free plan limits that actually matter
| Tool | Free accounts/channels | Free post limit | Biggest gap |
|---|---|---|---|
| Buffer | 3 (8 lifetime connections max) | 10 queued per channel | No X analytics history beyond 30 days |
| Metricool | 1 brand | 20 published posts/month | No LinkedIn, no X on free |
| Later | ~1 Social Set | Varies by account, roughly 30/profile/month at the paid Starter benchmark | No consistent published free-plan number anymore |
| Meta Business Suite | Facebook + Instagram only | Unlimited | Only 2 platforms, ~30-day scheduling window |
| Planable | Unlimited workspaces/users | 50 posts, total, ever (non-resetting) | No X publishing, no analytics |
| Publer | 3 accounts (no X) | 10 scheduled per account | Published posts vanish from the dashboard after 24 hours |

Buffer: still the most livable free plan
Buffer's free plan connects 3 channels and gives you 10 scheduled posts per channel sitting in the queue at once. That queue cap isn't a monthly reset; it's just how many posts can be lined up at a time, so once one publishes, you can slot in another. It supports all 11 networks Buffer offers, including Bluesky, Threads, TikTok, and YouTube, which matters if your brand lives outside the Facebook/Instagram bubble.
What surprised me is the AI Assistant is unlimited on free. Most competitors ration AI credits down to single digits per month; Buffer just gives you the caption rewriting and drafting tool without a meter running.
The catch almost nobody writes about: Buffer caps free accounts at 8 unique channel connections, ever. You can disconnect and reconnect channels within your 3-slot limit, but only 8 different accounts can ever pass through a single free Buffer login before you're forced to upgrade. If you're an agency testing client accounts on a free login, you'll hit that wall faster than the post limit.
Metricool: generous analytics, stingy on networks
Metricool's free plan gives you one brand and up to 20 posts published per month, resetting on the 1st. You can actually schedule more than 20 in the queue; the system just won't publish past that count until the next month starts, which is a nuance worth knowing before you panic that your posts disappeared.
Where Metricool gets unusually generous for a free tier is analytics: 30 days of history, competitor tracking on up to 5 profiles, and 5 AI caption credits a month. Where it gets stingy is network support: no LinkedIn, no X/Twitter on the free plan at all, only available as a paid add-on.
For a solo creator posting to Instagram, Facebook, and TikTok, Metricool's free tier is workable. For a B2B brand that lives on LinkedIn, it's a non-starter.
Planable: unlimited collaboration, a lifetime post ceiling
Planable flips the usual model. Instead of monthly limits, its free plan gives you unlimited workspaces and unlimited team members, no time limit on how long you can keep using it. The one number that matters is 50 posts, total, forever. It doesn't reset when a month rolls over and it doesn't reset when you delete old posts. Once you've created 50 posts on a free account, you're done unless you upgrade.
That structure makes Planable a genuinely good fit for agencies that want to trial the collaboration and approval-workflow experience with a client before committing, since the 50-post ceiling is roughly two to three weeks of daily posting across a couple of channels. It's a poor fit if you want an ongoing free scheduler for years.
X/Twitter publishing isn't included on the free plan, and neither are the analytics or social inbox add-ons.
Meta Business Suite: the only truly unlimited free scheduler
If your entire presence is Facebook and Instagram, Meta's own scheduler is free with no post cap at all. You can schedule Stories, Reels, and regular posts from a single dashboard, manage your unified inbox, and assign team permissions, all at zero cost, indefinitely.
The tradeoff is obvious: it's Meta only. No LinkedIn, no X, no TikTok, no Pinterest. And it can't schedule further than roughly 30 days ahead, so quarterly content calendars need a different tool anyway. Still, for a small local business that lives entirely on Facebook and Instagram, this is genuinely the best deal in the category because there's no ceiling to bump into.
Publer: solid limits, brutal post history
Publer's free plan connects 3 social accounts (X excluded) with 10 scheduled posts per account at a time and up to 25 saved drafts. It never expires and doesn't require a credit card.
The real limitation is that published posts disappear from your dashboard after 24 hours. If you want to look back at what you posted last week to check performance or just remember what you said, you can't, not on free. Publer's CEO has said publicly the company pays roughly $42,000 a month for X's Enterprise API, which is exactly why X access is walled off on every free tier across this category, not just Publer's. That's worth knowing if you've ever wondered why
