About

Post Once is a social media cross-posting and content-backup service for creators, small teams, and agencies managing multiple accounts. Users publish from a connected source account in its social platform's own app; Post Once automatically reposts new videos and photos, with captions, to destinations including Instagram, YouTube, Facebook Pages, Threads, X, and LinkedIn. Stories can be reposted between Instagram and Facebook Pages. Videos up to two hours and 4K are supported, with long videos routed to YouTube, Facebook, and LinkedIn. Posts, videos, and Stories can be backed up to Google Drive, Dropbox, Backblaze B2, or Amazon S3; captions are saved with posts and videos. The dashboard holds likely repeat posts for review to help prevent duplicates. The free plan includes 10 reposts and 10 backups; paid plans start at $9/month.
