Kinde is a developer platform that provides authentication, access management, billing, and feature management for building and monetizing modern SaaS products, targeted at engineers and SaaS founders.

---

🚀 Overview

Kinde is an all-in-one platform designed to simplify securing and monetizing SaaS applications by combining authentication, billing, feature flags, and access control into a single, easy-to-integrate service. It allows developers to add robust user authentication, manage subscriptions, and control features with minimal code, reducing the need for multiple vendors.

This project solves the fragmentation of tools for auth, billing, and user management, which often slows down development and increases costs. It's built for SaaS founders, indie makers, product teams, and enterprises—especially those handling B2B multi-tenancy—who want to launch secure, revenue-generating products quickly.

Kinde was created to empower engineers with modern, scalable infrastructure that cuts time to revenue by up to a year, offering better pricing and developer experience compared to legacy solutions like Auth0.
