Kinde

Hosted auth plus billing, $0 forever, 10,500 MAU, no OSS

Auth / Auth · Freemium

What's Good

Hosted, no OSS product. Free is $0 forever, no credit card, 10,500 MAU. Auth plus subscriptions/billing on Free. Billing take-rate 0.7%. Users charged more than USD $4/month via Kinde do not count as MAU. MFA, social, orgs, custom domain on Free.

The Catch

Not self-host. Kinde branding stays on Free. SMS is 10 included. Pro is $25/mo to uncap MAU and drop branding. Distinct from Polar (Apache MoR, not an IdP) and Clerk (auth UI, no 0.7% billing take-rate on Free).

Verdict

Hosted auth+billing with a real $0 forever plan. No repo to fork; branding until Pro.
