ReplyRush was created to help brands, creators, and agencies quickly turn Instagram and Facebook comments and mentions into private, automated DMs—saving time and boosting engagement from one easy dashboard. It was founded by Denis to solve the pain of repetitive, manual messaging and to offer unique automation features you won’t find together in other tools.
ReplyRush's answer
ReplyRush is built as a no-code, user-friendly automation tool for Instagram and Facebook, using an official integration with Meta’s API, and is managed entirely through a web and mobile dashboard. Users don’t need programming skills. Most likely, the underlying technologies are React or Vue.js for web interface, React Native or Flutter for mobile apps, Node.js or Python for backend automation, and PostgreSQL or MongoDB databases. Core features include instant DM automation, story/reels triggers, multi-account management, inbox automation, analytics, and integration with Facebook for secure account linking
