Post Once. Publish Everywhere.
Stop wasting hours uploading the same Reel, video, or image to every platform. OneUp automatically cross-posts your content from Facebook, Instagram, and TikTok to all your other accounts.
Watch How OneUp Cross-Posting Works
OneUp Cross-Posting vs. Scheduling Tools
Regular schedulers still make you log in, upload, and format for each platform separately. With OneUp cross-posting, you post a Reel to Facebook, Instagram, or TikTok and we automatically publish it everywhere.
Link Your Accounts
Connect all your social media accounts to OneUp using secure OAuth logins. Takes under a minute per platform.
Choose Source & Destinations
Choose your source account on Facebook, Instagram, or TikTok, then pick which accounts OneUp should automatically cross-post to.
Post Once — We Handle the Rest
Publish a Reel or video to your source account. OneUp checks for new content every 2 hours and automatically publishes it to every connected destination.
Why OneUp Cross-Posting?
-
Zero Manual Work

Up to 10 Destinations
