Best Cross-Posting Tools for Social Media in 2026
Cross-posting means making a post once and publishing it everywhere it fits: the same video to TikTok, Reels and Shorts, the same announcement to LinkedIn, X, Threads and Bluesky. Doing that by hand is the part of social media that eats a morning.
These 6 tools handle it in different ways and at very different prices. We build one of them (post bridge) and say where each one wins.
The short version
- One post to 10 platforms, flat price: post bridge
- Auto-copy new TikToks or YouTube videos elsewhere: Repurpose.io
- Free for up to 3 channels: Buffer
- Most features per dollar: Publer
- Self-hosted: Postiz
- A team with approvals: Hootsuite
Two kinds of cross-posting tool
Publish once, everywhere. You upload to the tool and it sends the post to every platform you pick, now or on a schedule. Most tools here work this way. You control the captions per platform and nothing carries another app's watermark.
Copy after the fact. You keep posting natively on one platform and the tool republishes new uploads to the others. Less control, almost no effort. Repurpose.io is the main example.
Whichever you pick, check the pricing model. Cross-posting is all about many accounts, and per-channel pricing charges for exactly that.
Best for: One post to 10 platforms, flat price, unlimited posts
Built for exactly this job. Upload a video or images once, write one caption (or a different one per platform), and publish or schedule to Instagram, TikTok, YouTube, X, LinkedIn, Facebook, Pinterest, Threads, Bluesky and Google Business Profile in the same post. Media is converted where a platform needs a different format. You can also cross-post from ChatGPT, Claude or a script through its MCP server, REST API and CLI.
Tradeoff: No free plan (7-day trial), no team approvals or inbox, and no automatic watching of a source account: you post through post bridge rather than it copying from TikTok after the fact.
$39/mo for 15 connected accounts, unlimited posts. $99/mo for 99 accounts.
Repurpose.io
Best for: Automatically copying videos from one platform to others
Works differently from a scheduler: you connect a source (a TikTok account, a YouTube channel, a podcast or a live stream) and it watches for new uploads and republishes them elsewhere, for example TikTok to Reels and Shorts, with watermark removal. Hands-off once the workflow is set.
Tradeoff: Video-first, and built around copying content that is already published rather than planning posts. Limits are per network on the lower plans.
Starter $35/mo (up to 3 accounts per network), Pro $79/mo, Agency $179/mo. 14-day trial.
Buffer
Best for: Cross-posting to 3 channels for free
Pick several channels in the composer and Buffer queues the same post to each, with per-network tweaks. The free plan (3 channels, 10 scheduled posts each) is the easiest way to try cross-posting without paying.
Tradeoff: Per-channel pricing, so cross-posting to many accounts is exactly what makes it expensive: 15 channels is about $90/mo on Essentials.
Free (3 channels), then $6 per channel per month.
Publer
Best for: Feature-dense cross-posting on a budget
Broad network coverage, bulk scheduling, recycling, and per-network caption variations, at low prices for small rosters.
Tradeoff: Priced per account, so the cost climbs as you add channels. The interface is busier than simpler tools.
Free tier; Professional from about $5/mo plus about $4/mo per extra account.
Postiz
Best for: Self-hosted cross-posting
Open source and self-hostable with wide channel coverage. If you would rather run a container than pay a subscription, it is the one to look at. A hosted version exists too.
Tradeoff: Self-hosting means you own the platform API changes, OAuth app approvals and upkeep.
Free to self-host; hosted from $29/mo for 5 channels.
Hootsuite
Best for: Teams cross-posting with approvals
Cross-posts across the major networks with approval workflows, a shared inbox and reporting on top. Built for teams where several people touch each post.
Tradeoff: Priced per user at enterprise rates; heavy for one person who just wants a post everywhere.
From $99 per user per month (annual billing).

Frequently asked questions
What is a cross-posting tool?
A tool that publishes one piece of content to several social platforms at once, so you do not upload the same video to TikTok, Instagram, YouTube and LinkedIn one by one. Most are schedulers with a multi-select composer. A few, like Repurpose.io, watch a source account and copy new uploads to other platforms automatically.
Can I cross-post without a third-party tool?
Partly. Meta lets you share Instagram posts and Reels to a linked Facebook Page, and YouTube Shorts and TikTok both accept the same vertical video. Nothing native reaches across companies, so posting to TikTok, YouTube, LinkedIn and X together still needs a tool or manual uploads.
Does cross-posting hurt reach?
Not by itself. What hurts is posting a video with another platform's watermark, or one caption that ignores each platform's limits and hashtag norms. Upload the clean original file and adjust captions per platform.
What is the cheapest way to cross-post to many accounts?
For 1 to 3 channels, Buffer's free plan. Past that, compare how each tool prices: per-channel tools grow with every account, while post bridge covers 15 accounts for $39/mo and 99 for $99/mo with unlimited posts. Self-hosting Postiz costs nothing but your time.
Can an AI agent cross-post for me?
Yes. post bridge connects to ChatGPT, Claude and any MCP client, so you can ask an assistant to post a video to TikTok, Reels and Shorts in one message. Postiz also has an agent story if you self-host.
