The best social media scheduling tools, judged on vertical video
Every scheduler handles a photo fine. They separate on video — file size caps, codecs your iPhone uses by default, cover images, and which formats a tool will publish without you.

How each scheduler charges, taken from its own pricing page in August 2026. The units are not comparable — a Buffer channel, a Later social set and a Sprout seat buy different things. Prices change; check before committing.
| Tool | Charged by | Entry paid tier | Free plan |
|---|---|---|---|
| Buffer | Connected channel | $5 per channel/mo, billed annually | 3 channels, 10 posts each |
| Later | Social set of 8 profiles | $18.75/mo, billed annually | None — 14-day trial |
| Metricool | Number of brands | Published as a regional range | 1 brand, 20 posts/mo |
| Hootsuite | Plan, up to 10 accounts | $99/mo, billed annually | None — 14-day trial |
| Sprout Social | Seat | Per seat, profiles capped by tier | None — 30-day trial |
Pick a scheduler on how it handles video, not on its calendar
Every scheduler on the market has a calendar, a queue, a caption box and an AI button, and comparing those gets you nowhere because they are all roughly the same. The differences that matter show up the moment you put a vertical video in the queue: whether the file is accepted, whether it publishes on its own or waits for you to tap a notification, and whether the version that goes live looks like the one you exported. This guide is about which product to pay for and what each one costs. The platform rules that constrain all of them equally — what Instagram, TikTok and YouTube themselves permit — are a separate subject, covered in the mechanics guide linked at the end.
The failure that catches almost everyone: your phone's codec
Buffer's help documentation on video upload troubleshooting names the culprit plainly, and it is not file size. The codec is the setting that matters, H.264 is the one to use, and iPhones and Macs record in HEVC (H.265) by default, which frequently fails. Metricool's publishing requirements say the same thing in different words: HEVC files are not compatible with automatic publishing, and HDR video from an iPhone will not publish through the API either. Buffer also warns off ProRes, AV1 and RED footage. The fix is dull and permanent — export H.264 MP4 with AAC audio at 128 to 192 kbps, 1080p, under 25 Mbps, and stop thinking about it. Most people blaming the scheduler are actually handing it a file no platform API will take.
File size and length caps differ by tool, not only by platform
The same clip can pass in one product and bounce in another. Buffer publishes per-network maximums that vary widely: 40MB for Mastodon, 100MB for Bluesky, 300MB for Instagram, 1GB for Facebook, X, LinkedIn, Pinterest, TikTok and Threads, and 10GB for YouTube Shorts. Metricool applies a flatter 500MB ceiling across Instagram Reels, TikTok and YouTube Shorts. Later's guidance is stricter still, advising you keep videos under 100MB and at 1920 by 1080 to preserve quality on upload. Buffer also notes that X accepts roughly 140 seconds of video through third-party tools. If you shoot long or export at high bitrate, check the ceiling before you commit to a product, because it is the one limit you cannot work around with a setting.
What "supports Reels" actually means in each product
Support is not binary, and the exceptions cluster around the parts of a Reel people care about. Metricool documents its own list: Reels using audio that is not in Metricool's library cannot be auto-published, nor can Reels carrying polls, questions, quizzes, sliders or countdowns, and its audio library is smaller than Instagram's because only tracks cleared for third-party use come through. Later's help centre puts auto-published Reels at up to three minutes from desktop and iOS but 90 seconds from Android. Buffer supports YouTube Shorts and not long-form YouTube, does not support custom thumbnails on Shorts, and passes through YouTube's own limit of 10 posts per 24 hours for unverified channels. Read the exceptions list, not the feature list.
The pricing models are not comparable, and that is the real decision
Four vendors, four different units. Buffer charges per connected channel — one Instagram profile, one TikTok account — at $5 per channel per month on annual billing for Essentials, $10 for Team. Later sells social sets, a bundle of one profile on each supported network, with Starter at $18.75 a month annually for one set and a cap of 30 posts per profile per month. Hootsuite prices by plan, with Standard at $99 a month on annual billing for up to ten accounts. Sprout Social prices per seat, with social profiles capped on the lower tiers. Metricool charges by number of brands. Work out your real channel count first, because that number, not the headline price, decides which model is cheapest for you.
The free tiers, and what you can genuinely run on nothing
Two of the five have a permanent free plan and it shows in who uses them. Buffer's free tier covers three channels with ten scheduled posts each, one user, and 30 days of analytics history, which is enough to run a small account indefinitely. Metricool's free plan covers one brand, 20 scheduled posts a month, and 30 days of analytics, and excludes LinkedIn and X. Later, Hootsuite and Sprout have no free tier at all — Later and Hootsuite offer 14-day trials, Sprout a 30-day one. If you are one person posting a few clips a week, the honest answer is that a free plan does the job and the paid upgrade should wait until the post cap is the thing slowing you down.
Which one, by situation
If you run three or four accounts on your own, Buffer's per-channel pricing is the cheapest way to a working queue and its free tier will hold you for a while. If you publish heavily across every network under one brand, Later's social set maps neatly onto that shape, provided the post cap on the entry tier clears your volume. If analytics matter as much as publishing, Metricool bundles both and its free tier is the most generous starting point. Hootsuite and Sprout are team products — approvals, inboxes, seats, reporting — and the price reflects that; buying one for a solo channel is paying for coordination you do not need. Nobody should be choosing on the AI caption button.
The queue is rarely the bottleneck
Once a scheduler is set up you touch it for a few minutes a week, which is a clue about where the real constraint sits. Most empty queues are not a tooling problem, they are a supply problem: there was nothing cut, captioned and sized to put in them. That is the step worth attacking first, and it is what FrameOS does — take one long recording, pull the moments worth posting, reframe them vertically and burn in captions, so a week of vertical video comes out of a single session. You can run it on your own footage with 300 credits for 3 days · no card. Whichever scheduler you land on, export H.264 and fill the queue in one sitting.
FAQ
What is the best social media scheduling tool for Reels and Shorts?
For one person running a handful of accounts, Buffer is the cheapest route to a working queue at $5 per channel per month on annual billing, and it publishes Reels, TikTok and YouTube Shorts. Metricool is the better pick if you want analytics bundled in, and its free tier covers one brand. Neither can auto-publish a Reel using trending audio.
Why does my video fail to upload to my scheduler?
Usually the codec. Buffer's troubleshooting guide names H.264 as the most important setting and notes that iPhone and Mac footage defaults to HEVC (H.265), which frequently fails. Metricool states outright that HEVC files and iPhone HDR video are not compatible with automatic publishing. Re-export as an H.264 MP4 with AAC audio at 1080p and the problem usually disappears.
Is there a free social media scheduler worth using?
Two. Buffer's free plan gives you three channels, ten scheduled posts per channel and 30 days of analytics history with no time limit. Metricool's free plan covers one brand, 20 posts a month and 30 days of analytics, but excludes LinkedIn and X. Later, Hootsuite and Sprout Social offer trials only, at 14, 14 and 30 days respectively.
Should I pay for Hootsuite or Sprout Social as a solo creator?
Probably not. Both are built for teams — approval workflows, shared inboxes, seat-based reporting — and priced accordingly, with Hootsuite's entry plan at $99 a month on annual billing and Sprout charging per seat. If nobody has to approve your posts and nobody else answers your DMs, you are paying for coordination features you will not open.
