AuthGPTs

AuthGPTs is the developer toolkit that handles everything you don't want to build from scratch when turning your GPT into a real SaaS product. API security, user management, authentication flows — these are the unsexy but critical pieces that can take weeks to get right. AuthGPTs gives you all of it, out of the box.

Built on Next.js, it brings OAuth 2.0 authorization, OTP email integration, endpoint security, and seamless integration with Cloudflare and Next.js APIs. Layer on analytics and payment systems, and you've got a complete, production-ready SaaS infrastructure — so you can focus on what your GPT actually does, not on the plumbing around it.
