About

Gemmein turns an app your AI builds in ChatGPT or Claude into a real business. Your AI writes the app; Gemmein runs the rest: sign-in, each customer’s data kept apart, payments and your own domain. Customers sign in with a code sent to their email, so there are no passwords to forget, reset or leak. Subscriptions, one-off payments and credit packs are paid straight into the Stripe account you connect. Sign-in codes, receipts and notices are sent from your own domain, and your AI drafts replies to customer emails for you to approve. One app runs on the web, iPhone, Android and Mac. Every Live change waits for your approval. Building is free, with no card until you go live. Starting price: $29 / month Pricing details: Build: $0, no card until you go live. Launch: $29/month (up to 5 apps). Run a business: $79/month (up to 10 apps). Grow: $199/month (up to 25 apps). One flat price per account. Annual billing: 2 months off. Free version: Yes. Building is free. Free trial: No. Le

About

SignOps is a hosted developer API for adding push messaging and sign-in flows to web and mobile applications. Developers can register devices under their existing user IDs, send Android, iOS and web push messages to users or topics, schedule messages, use templates, and review delivery events. The service also provides phone-based login approvals with number matching and biometric confirmation, passkey sign-in on a customer’s domain, TOTP authenticator codes with backup codes, and email one-time passwords. REST endpoints, server SDKs, mobile and web SDKs, a team dashboard, and signed webhooks support integration with an application’s existing backend and identity provider. It is designed for developers and teams building applications that need notifications, passwordless authentication, or additional sign-in verification.
