Tool profile
Authentication, user management, feature flags, and billing infrastructure for modern SaaS products.
SaaS authentication and user management
Kinde is a developer-first identity platform that now reaches beyond login. It combines authentication, user management, B2B organizations, enterprise SSO, machine-to-machine access, feature flags, workflows, and Stripe-backed billing in one control plane.
That breadth makes Kinde especially interesting for SaaS teams that want auth and monetization to share the same product model. It is not the lightest possible auth library, and teams that only need a few passwordless screens may prefer a narrower tool. But for products that need users, organizations, entitlements, and subscription gates to evolve together, Kinde gives you a unusually pragmatic middle ground between hand-rolled identity and enterprise IAM complexity.
Quick fit
Editorial take
Kinde's real distinction is consolidation. Evaluate it when auth, billing, organizations, and feature entitlements are part of one product operating model, not when you simply need the smallest possible login layer.
