Kinde

Hosted auth with built-in billing

Free tier + paidAuth & user managementkinde.com

What it is

Hosted auth and user management with organizations, roles, feature flags and built-in subscription billing. Free to 10,500 monthly active users. Paid plans start at $25/mo with overage at $0.0175 per MAU, and Kinde takes 0.5-0.7% of volume when you bill customers through it.

Why it earns a slot

One of the few auth vendors that also sells billing and entitlements, so a solo builder ships signup, plans and feature gating without wiring in a second product.

Know before you commit

Bundling auth and billing deepens lock-in — migrating away means moving users and live subscriptions at the same time. Kinde's billing fee stacks on top of Stripe's own processing fee.
