PostOnce

PostOnce is a social media crossposting tool and scheduler that lets you publish and schedule content to TikTok, Instagram, YouTube, Facebook, X, LinkedIn, Threads, Pinterest, and Bluesky from one place. Instead of logging into nine different apps, copying captions, re-uploading the same video, and keeping track of what went where, you create your post once and let PostOnce handle the distribution. It is built for creators, marketers, and agencies who want to show up consistently across every major platform without spending hours on repetitive manual work.
Crossposting is the heart of PostOnce. Upload a video, image, or text update a single time and send it out to all of your connected channels automatically. Short-form video creators can push the same clip to TikTok, Instagram, YouTube, and Facebook in one step, while writers and brands can share updates to X, LinkedIn, Threads, and Bluesky together. Visual content can go to Pinterest as well, so your work reaches each audience wherever they spend their time.
Scheduling is built in. Plan your content calendar ahead of time, queue posts for the moments your audience is most active, and keep a steady publishing rhythm even on busy days. This makes PostOnce a practical Buffer alternative for anyone who wants crossposting and scheduling combined in one simple workflow.
Creators use PostOnce to grow on several platforms at once without multiplying their workload. Marketers use it to keep campaigns consistent across channels and save time on routine publishing. Agencies use it to manage content for multiple clients from a single dashboard, which keeps operations organized as they scale.
Pricing is straightforward. You can start with a free trial to see how PostOnce fits your workflow. Paid plans include Creator at $29 per month, Pro at $69 per month, and Agency at $199 per month, so individuals and teams can pick the level that matches their needs.
PostOnce was founded by Nigel Yong in Montreal, Canada. The goal is simple: post once, and reach everywhere.
