PostOnce

PostOnce helps you cross-post without re-uploading. Connect the social accounts you already use, post in your primary app, and PostOnce publishes the same video to your other connected platforms—typically within about 20 minutes.

The core workflow is simple: you connect accounts, pick the main app you’ll post from, and then PostOnce handles the distribution using each platform’s official posting APIs. Set it up once, and your ongoing content posting can run on autopilot with “unlimited workflows” and “unlimited posts” depending on your plan.

PostOnce supports nine platforms: Instagram, YouTube, Facebook, X/Twitter, LinkedIn, Threads, Bluesky, TikTok, and Pinterest. It’s built for UGC creators, coaches and personal trainers, small businesses, theme pages, artists and musicians, realtors, and agencies or social media managers managing multiple client accounts.

Plans are account-based and include features like existing content publishing and image repurposing, with Developer API + MCP on all tiers. There’s a 7-day free trial with no credit card required, and you can cancel anytime. Pricing is available for Creator ($29/month billed monthly or $24/mo billed annually), Pro ($69/mo or $58/mo billed annually), and Agency ($199/mo or $166/mo billed annually), with annual billing discounts shown.
