About

OnlyStack is OnlyFans agency management software for agencies, managers, and creators running one or more creator accounts. It brings account chats and fan details into a shared workspace, with spend history, notes, subscription information, and past purchases beside conversations. Teams can send paid vault content, organize fans, send mass-message sequences, and automate welcomes, follow-ups, online-fan nudges, and scheduled posts or stories. Analytics track account activity, while individual logins, roles, and creator assignments help managers and chatters work across accounts. OnlyStack offers a web workspace, a macOS and Windows desktop app, and a Chrome extension. Paid plans add automations and, on Pro, AI agents that learn about fans, make content offers, reply to unanswered chats, and re-engage buyers under agency-set limits. A read-only MCP server lets compatible AI apps query account and team data.
