How to Post to All Social Media at Once: 7 Best Apps (2026)

Prices and plan limits checked November 6, 2026.

You can't post to all social media at once from inside Instagram, TikTok or YouTube: none of them posts to all the others. To post everywhere at once, you need a cross-posting app that connects to each network through its official API and sends one post to all of them.

The best apps to post to all social media at once are:

1. PostOnce: post natively on one app and it goes out everywhere else automatically
2. Socialync: upload once, pick networks, post now or later
3. Post Bridge: upload once and publish to many networks
4. Buffer: a simple queue for scheduling to several channels
5. Metricool: posting plus analytics in one dashboard
6. SocialBee: category queues that recycle evergreen posts
7. Repurpose.io: automated video workflows between networks

Pick the app by where you want to create the post. If you like posting in the TikTok or Instagram app, use a tool that copies those posts automatically. If you'd rather build every post in a dashboard, use an upload-once app.

Disclosure: PostOnce publishes this guide and is one of the apps listed. Other apps were checked against their official pricing and help pages on November 6, 2026. Prices change, so confirm a plan before you buy.

Can you post to all social media at once?

Yes, with a third-party app. Instagram can share a post to Facebook, but no social app posts to all the others. A cross-posting app fills that gap: you connect your accounts once, and each post goes to every network you choose.

There are two ways these apps work:

• Post once in your favourite app. You keep posting on TikTok, Instagram or YouTube as usual. The tool sees each new post and republishes it to your other accounts. PostOnce and Repurpose.io work this way.
• Upload once in a dashboard. You upload the video or image to the tool, write a caption, tick the networks, and publish now or schedule it. Socialync, Post Bridge, Buffer, Metricool and SocialBee work this way.

Best apps to post to all social media at once, compared

Competitor prices are listed per month as shown on their pricing pages.

1. PostOnce: best for posting once and sharing everywhere automatically

PostOnce is built for one job: you post on one network, and the same post appears on your other accounts. You set up a workflow once (for example, TikTok to Instagram Reels, YouTube Shorts and Facebook) and every new TikTok goes out to those accounts without you opening another app.

You can also upload a post in PostOnce and send it to several networks at once, or schedule it for later.

• Networks: TikTok, Instagram, YouTube, Facebook, LinkedIn, X, Threads, Bluesky and Pinterest, through each platform's official API.
• Formats: videos, photos and carousels, plus Instagram and Facebook Stories to your other Instagram accounts and Facebook Pages. TikToks go out without the watermark where available.
• Older posts: repost 1 to 5 a day from your back catalog.
• Speed: for posts set to go out immediately, half are live on their destinations within about 10 minutes, most within 20.
• Reliability: 99.7% of crossposts went out in the 30 days to November 10, 2026, not counting account issues such as a disconnected or suspended account.
• Price: Creator costs about $0.79 a day billed yearly ($290/year), or $29 month to month, for 15 accounts and unlimited posts. Try it free for 7 days with up to 10 posts and no card.

Choose PostOnce if you already post in TikTok, Instagram or YouTube and want everything else to happen on its own. See every supported route in the crossposting directory.

2. Socialync: best simple upload-once app

Socialync lets you create one post, choose networks and publish now or schedule it. It covers 9 networks: TikTok, Instagram, YouTube, Facebook, X, LinkedIn, Threads, Bluesky and Pinterest.

Starter is $20 a month ($15 a month billed yearly) for 5 accounts and unlimited posts. The free plan allows 5 posts a month on up to 5 accounts, without a card.

Choose Socialync if you post a few times a week and want a simple dashboard at a low price.

3. Post Bridge: best for uploading once to many networks

Post Bridge is built for uploading a post once and publishing it to 10 platforms, which suits creators who run several accounts per network.

Marketer is $39 a month for 15 accounts and unlimited posts, with a 7-day trial.

Choose Post Bridge if you schedule lots of videos to lots of accounts from one place.

4. Buffer: best for a simple posting queue

Buffer is one of the simplest ways to schedule to several networks. You write a post, pick channels, adjust each version and add it to a queue. It covers Instagram, Facebook, X, LinkedIn, Pinterest, YouTube, TikTok, Threads, Bluesky, Mastodon and Google Business.

The free plan covers 3 channels with 10 scheduled posts per channel. Paid plans start at $5 per channel per month.

Choose Buffer if you want a clean calendar and queue with almost no setup.

5. Metricool: best for posting plus analytics

Metricool puts a posting calendar and each network's analytics in one place, organised by brand. It covers Facebook, Instagram, Threads, X, Bluesky, Pinterest, TikTok, YouTube, Twitch, LinkedIn and Google Business Profile.

Starter is €16 a month billed yearly (€20 month to month) for 5 brands. The free plan covers 1 brand and 20 scheduled posts a month.

Choose Metricool if you want to see what works on each network in the same place you schedule.

6. SocialBee: best for recycling evergreen posts

SocialBee sorts posts into categories (tips, promotions, curated links) and fills a schedule from each one, so a queue never runs empty. It posts directly to Facebook, Instagram, Threads, LinkedIn, X, Pinterest, TikTok, YouTube, Google Business Profiles and Bluesky.

Bootstrap is $29 a month ($24 a month billed yearly) for 5 social profiles; Accelerate is $49 for 10 and Pro is $99 for 25. Every plan starts with a 14-day trial without a card.

Choose SocialBee if you want a steady mix of evergreen posts rather than copying each new post everywhere.

7. Repurpose.io: best for automated video workflows

Repurpose.io connects a source (TikTok, Instagram, YouTube, Facebook, Google Drive or Dropbox) to destinations through workflows. Each new TikTok, for example, can go to Instagram automatically, without the watermark.

Starter is $35 a month ($349 a year) for up to 3 accounts per network and 5,000 published videos a month. The trial covers 14 days or 10 published videos, with no card.

Choose Repurpose.io if you mostly post video and want sources beyond social apps, such as Drive folders.

How to post to all social media at once, step by step

The steps are almost the same in every app:

1. Pick an app that supports every network you need. Check formats too: a Reel, a carousel and a text post are handled differently.
2. Connect your accounts. You sign in to each network through its official login screen. Instagram needs a Business or Creator account, and Facebook needs a Page.
3. Create the post. In a dashboard app, upload the video or image and write the caption. In PostOnce, you can instead choose a source account and the accounts it should feed.
4. Adjust per network. Shorten the caption for X, change hashtags for LinkedIn, or pick a different cover for YouTube.
5. Publish or schedule. Post now, pick a time, or let new posts go out automatically.

Here's how it looks in PostOnce: connect TikTok, Instagram and YouTube, create a workflow with TikTok as the source, and post your next TikTok as normal. Usually within 10 to 20 minutes it's on Instagram Reels and YouTube Shorts.

How to post to all social media at once for free

Most apps let you start free, but the limits differ:

• Socialync: 5 posts a month on its free plan.
• Buffer: up to 3 channels, with 10 scheduled posts per channel.
• Metricool: 1 brand and 20 posts a month.
• PostOnce: a 7-day trial with up to 10 posts on every network, no card needed.

If you post a few times a month to two or three networks, a free plan may be enough.

How to post a TikTok to all your other accounts

TikTok is the most common starting point. If you film for TikTok first, you can send each video to:

• Instagram Reels
• YouTube Shorts
• Facebook Reels

PostOnce's most-used route is TikTok to YouTube Shorts, run by 149 customers as of September 2026. Instagram creators can do the same in reverse: Instagram to TikTok and Instagram to YouTube.

Does posting the same thing everywhere hurt reach?

Not on its own. Cross-posting apps publish through the same official APIs that every scheduler uses, so each network sees a normal upload. When we compared views before and after 40 YouTube channels started posting through PostOnce, there was no consistent drop: the share of Shorts under 10 views went from 9.8% to 9.5%. PostOnce's founder grew How2Rizz to about 15k TikTok followers, 10k on Instagram and 4,800 YouTube subscribers posting the same videos everywhere through PostOnce.

What matters more is the account. A new account with no history may get little reach whatever tool you use, so post a few times natively before you automate. Then adjust what each network rewards: hashtags on Instagram, a clear title on YouTube, a shorter caption on X.

Yes. PostOnce, Socialync, Post Bridge, Buffer, Metricool, SocialBee and Repurpose.io all post to several networks at once. PostOnce can also copy each new post from TikTok, Instagram or YouTube to your other accounts automatically.

How do I post the same video on TikTok, Instagram and YouTube at once?

Connect all three accounts to a cross-posting app, then either upload the video once and choose all three, or post it on one app and let a workflow copy it to the other two.

For light use, yes. Socialync's free plan allows 5 posts a month, Buffer's covers 3 channels and Metricool's allows 20 posts a month. PostOnce has a 7-day trial with up to 10 posts and no card.

Buffer and Metricool each cover 11 networks, Post Bridge 10, and PostOnce and Socialync the 9 main ones: TikTok, Instagram, YouTube, Facebook, LinkedIn, X, Threads, Bluesky and Pinterest. Check that the plan you pick includes every network you use: free plans don't always include every network.
