Kinde
Developer auth platform with billing built for startup SaaS.
About
Kinde is an Australian authentication and user-management platform founded in 2021, aimed at startups that want auth plus monetization in one place. It covers email, SMS and social login, MFA, organizations for B2B, attack protection, machine-to-machine apps and feature flags, with the UI customizable via HTML, CSS or React.
Its differentiator is first-class subscriptions and billing: plans can be created and revenue collected directly through the platform. A 2026 buyer's guide rated it the best value option among auth providers for startups. Pricing aggregators report a free tier around 10,500 monthly active users and a Pro plan starting at $25 per month, but those figures change, so confirm on kinde.com.
