What is Gemmein and how does it work?
Gemmein is the backend for AI-powered products on web and mobile. It gives an app everything it needs to reach paying customers in one place: passwordless sign-in, protected data with per-person access rules, file storage, server-side AI on your own provider keys, credits and payments through Stripe, transactional email from your own domain, and a support inbox. It is built to be used by AI coding agents. Paste one prompt into Claude Code, Cursor or Codex and the agent reads Gemmein's guide, builds the backend into your app, and takes it live. Rules are enforced on Gemmein's servers, so customers' data stays private and keys never ship in browser code. One dashboard runs the business after launch: customers, subscriptions, payments, AI usage and credits, email, support conversations, and a complete log of every action. Development is free with no card; going live starts at $50 a month. Gemmein Limited is registered in England and Wales.
