Free Content Calendar Tools (2026): 8 Tools and Their Limits

There are two jobs hiding inside a content calendar. One is planning: deciding what goes out, when and where. The other is queuing: loading posts so they publish on time. Free tools split along that line, and the split decides which one you need.

I've picked eight tools with a free plan or free licence as of Nov 2026, grouped by where the free limit bites, and listed them in no particular order. Every limit comes from the vendor's own page, and feature claims are labelled as the vendor's. If you're judging tools purely as schedulers, see this roundup of free social media schedulers.

The queue fills up long before the calendar does

Here's where people come unstuck. The calendar view is free almost everywhere. What's capped is the number of posts waiting in the queue. One scheduler holds ten scheduled posts per channel, another ten per account, and another twenty posts in a month. Plan a full month ahead and you'll hit the free limit within days.

The routes without a queue limit come with their own work. They're self-hosted, so you run the server, keep it updated and fix it when it breaks. One of them also publishes to far fewer networks on its free licence.

That's why the sensible free setup is usually two tools, not one: a planner for the long view and a scheduler for the short one.

Schedulers that limit the queue

Buffer connects up to 3 channels on its free plan and holds 10 scheduled posts per channel at a time, refilled as posts go out, as of Nov 2026. The vendor says the free plan stays free forever.

Publer connects 3 social accounts on free, though X accounts can't be connected, and holds 10 scheduled posts per account at a time. Published post history is kept for only 24 hours, so note anything you need for reporting straight away.

Metricool manages 1 brand on free and schedules up to 20 posts per month, with no LinkedIn or X connections and 30 days of analytics.

Run it yourself and the limits change shape

Mixpost Lite is a free licence you deploy on your own server, not a hosted free plan. Lite publishes only to Facebook Pages, Mastodon and X profiles, with basic analytics and community support, and publishing to every platform sits in its Pro licence.

Postiz is open source under the AGPL-3.0 licence, per its GitHub repository, and you run the server yourself. Its hosted cloud version has no free plan. If you modify the code and offer it to others, the AGPL terms apply.

Planners you fill in by hand

These don't publish for you, but they're where the long view lives. For more planners in this style, there's a wider list of social media content calendar tools.

Zoho Social's free plan lists a publishing calendar, scheduling and drafts for a single brand with a small set of channels and a few AI credits, as of Nov 2026. Support on free is by email on weekdays only.

ClickUp isn't a social tool at all, but its free plan lists a calendar view, Kanban boards and unlimited tasks, per the vendor, which is plenty for planning content. The limits are 60 MB of storage and a single form, and custom fields and Gantt charts need an upgrade.

Asana's free Personal tier offers list, board and calendar views. It's built for personal projects, files are capped at 100 MB each, and team features sit in higher tiers.

My advice: plan long, schedule short

Don't try to make one free tool do both jobs. Keep the whole quarter in a planner with a calendar view, where nothing is capped by post count, and move only the next fortnight into a scheduler. You'll stay well inside a ten-post queue, you'll be able to swap posts when news changes, and you won't lose weeks of work if a free tier changes. Self-host only if someone on your team is happy to look after a server.

A fortnightly routine that stays inside free limits

1. Every other Monday, review the planner and pick the posts for the coming two weeks.
2. Write and approve them in the planner, where drafts don't count against a queue.
3. Load them into the scheduler, checking the per-channel or monthly limit first.
4. Record what went out, since some free plans keep post history only briefly.
5. Move unused ideas back into the planner for the following cycle.

Frequently asked questions

Can a free content calendar tool publish posts for me?

Some can. The schedulers here publish from a queue, within their free limits. The general planners show your content on a calendar, but you post it yourself or hand it to a scheduler.

How many posts can I schedule for free?

It depends on the unit. Some free plans count posts per channel or per account at a time and refill as posts go out, while one counts posts per month. Self-hosted tools don't list a queue cap, but you run them yourself.

Is a self-hosted scheduler really free?

The licence is free, but you supply the server, the updates and the fixes. One self-hosted option here also limits which networks it publishes to on the free licence.

Can I plan content in a project management app?

Yes. Task managers with a calendar view work well for planning, briefs and approvals. They just won't publish to social networks, so pair one with a scheduler.

Do free schedulers support X and LinkedIn?

Not all of them. One free plan here excludes LinkedIn and X, and another excludes X accounts, as of Nov 2026. Check the networks you rely on before you plan around a tool.

How far ahead should I schedule on a free plan?

About two weeks. That keeps you inside the queue limits and leaves room to change posts when plans shift.
