Frequently Asked Questions
What is PostOnce?
PostOnce lets you post a video in the app you already use and automatically publishes it to nine major social platforms—including TikTok, Instagram, YouTube Shorts, Facebook, LinkedIn, X, Bluesky and more—through each platform’s official posting APIs. After connecting your main account, a new post is sent to all linked accounts within about 20 minutes, requiring no technical skills and taking roughly a minute to set up. The service offers a 7‑day free trial with no credit card required, then provides paid plans that scale with the number of social accounts you manage: $290 annually for up to 15 accounts, $690 annually for larger teams with priority human support, and $1,990 annually for agencies handling client accounts. All plans include unlimited workflows, posts, scheduling, existing‑content tools, and human support, plus a full refund within seven days.
