The best apps to cross-post short videos to TikTok, Reels and Shorts

To cross-post one short video to TikTok, Instagram Reels and YouTube Shorts, use a scheduler that publishes to all three through their official APIs; what separates them is the price of the three networks together, whether the free plan includes TikTok, and who writes each caption. Billed monthly on Oct 3, 2026, all three cost $9 on PostWire (which also writes a different caption, YouTube title and tags for each), €14.99 on ShortSync, $18 on Buffer or Hopper HQ, $20 on Socialync, $24 on Upload-Post, $25 on Metricool or OneUp, $29 on Blotato, $35 on Repurpose.io and $39 on Post Bridge. Free to start: PostWire, ShortSync, Buffer, Socialync and Metricool.

Every price was read on the vendor's own pricing page on Oct 3, 2026 (links in the table and at the bottom). "All three" means the cheapest plan that publishes one video to TikTok, Instagram and YouTube for one creator, billed monthly. Yearly billing is cheaper on most of them.

The apps, by what TikTok + Reels + Shorts costs on each

Ordered by the monthly price of publishing to all three networks, cheapest first — the one number every reader can check. PostWire is ours; it comes first on that number, and the box below the table says where the others beat it.

    Free plan
    No — 7-day trial
    Cheapest paid plan
    Marketer $39 a month — 15 accounts, unlimited posts

    15 accounts and unlimited posts on Marketer, with an MCP server and a Claude integration.

    Watch out: The highest entry price here.

PostEverywhere (Lite $9 a month for 2 accounts; three networks need a higher plan) and Later (no free plan; the monthly-billed price isn't in its page source) are left out of the order because we couldn't put a verified number on all three networks.

How it works in PostWire (5 minutes)

  1. Create a free PostWire account

    Open postwire.io/dashboard.html, type your email and press Create my free account. PostWire emails you a link to confirm the address; connecting accounts and publishing unlock once it is confirmed. No password and no card (free plan: 1 business, 20 posts a month, 5 AI drafts a day, 2 networks per post, 3 scheduled posts at a time — every network connects free, no card).

  2. Connect TikTok, Instagram and YouTube

    Open Accounts, press Connect on each network and then Continue to TikTok (or Instagram, YouTube). You sign in on the network itself and come straight back; PostWire never sees your password and you do not need your own developer app — PostWire's TikTok, Meta and Google approvals cover it. Instagram needs a Business or Creator account; Log in with Instagram works without a Facebook Page.

  3. Add the video and press Write the posts

    In Compose, write one line in Your idea, tick TikTok, Instagram and YouTube under Post to, drop the file on Add photos or a video, and press Write the posts. Each network gets its own draft; edit anything.

  4. Publish or schedule

    Choose TikTok's Who can view this video, then Publish now or Schedule → Add to queue. Each network returns its own link. Full walk-through: post the same video to TikTok, Reels and Shorts.

Each vendor's own pricing page (or its pricing.md / llms-full.txt), read on Oct 3, 2026. "All three" = the cheapest plan that publishes to TikTok, Instagram and YouTube for one creator, billed monthly. Monthly billing in USD unless noted. "Not listed" means we could not find it on their page, not that it is missing.

Where the others are ahead of PostWire

  • More networks: Buffer, Upload-Post, Blotato, Post Bridge and others reach X, Threads or Pinterest. PostWire has 9 networks and none of those three.
  • Analytics and engagement: Metricool and Buffer report on your accounts. PostWire's What works only ranks your posts against your own median.
  • Automatic re-posting and AI video: Repurpose.io re-posts on its own; Blotato makes the video. PostWire publishes the file you give it.
  • A bigger free tier for posts to all three: PostWire's free plan sends each post to 2 networks; ShortSync's free 5 uploads go everywhere. All three at once on PostWire is the $9 plan.

Questions people ask

What is the best app to cross-post short videos to TikTok, Reels and Shorts?

It depends on what you need. Cheapest for all three (billed monthly, Oct 3, 2026): PostWire at $9, which also writes each network's caption, YouTube title and tags. ShortSync (€14.99) is short-video-only; Buffer ($6 per channel) is the mature scheduler; Repurpose.io ($35) re-posts automatically from an account you already use.

Is there a free tool to schedule TikTok, Instagram Reels and YouTube Shorts from one place?

Yes. On Oct 3, 2026 PostWire (20 posts a month, TikTok included, 2 networks per post), ShortSync (5 uploads a month), Socialync (5 posts a month), Buffer (3 channels, 10 scheduled posts each) and Metricool (1 brand, 20 posts a month) had free plans. Upload-Post's free plan excludes TikTok.

Can I post the same video with a different caption on each network?

Yes. In PostWire you upload once and press Write the posts: TikTok gets a hook-first caption, Instagram a shorter caption, YouTube a title, description and tags. Buffer's and Metricool's AI assistants also tailor a post per platform, one network at a time.

Will Instagram post it as a Reel and YouTube as a Short?

Instagram publishes a video through its API as a Reel. YouTube decides from the video itself: vertical and under 60 seconds is shown as a Short.

Do these apps edit or clip the video?

Most publish the file you upload. Blotato makes AI video and Repurpose.io re-posts existing videos; PostWire publishes your file as is (no cropping or re-encoding of video).
