What is PostOnce?
Content written once goes live across nine connected social networks from a single workspace, removing the need to open eight separate apps. PostOnce handles the handoff to each platform, whether the user publishes immediately, slots posts into a recurring queue, or schedules content for later dates.
Connecting accounts and managing failures
Users link their existing social channels through OAuth connections. When a network rejects a post or an authorization token expires, the application surfaces the error with a clear next step instead of leaving posts to fail silently. Account health banners show when a login requires a manual reconnect, and temporary issues trigger retry options.
Workspace features and media tools
Built by Lucro Limited in Ireland, the platform includes a shared media library to store and reuse approved assets without hunting through external folders. Optional per-network media sizing automatically adjusts files to meet platform requirements. The Solo plan supports ten social accounts and two team members, while the Pro plan expands access to unlimited social accounts, three separate workspaces, roll-up reporting, and a REST API for automated workflows. Flat monthly or annual pricing applies across all plans without additional charges for each connected channel.
