Auth · working at 10,000 users · rates as read 24 Sept 2026
On free tier, Kinde is $0 forever: 10,500 monthly active users and PropelAuth is $0: includes 10,000 MAUs. On cheapest paid plan, Kinde is $25 USD per month (Pro) and PropelAuth is $150 /month (Growth). On rate above what's included, Kinde is $0.0175 per extra monthly active user, stepping to $0.0151 and PropelAuth is $0.05 per user above 10,000, $100/connection for SSO. StackTab sells neither of these and takes no referral fee on either: it scores them. Every figure was read off the named company's own page on or since 2026-09-18; the URLs and the dates are at the foot of this page, and a job re-fetches each one on a schedule and fails when a figure is no longer on the page it came from.

Kinde: You want the billing and the auth on one bill. Kinde is the only provider in this table that also runs your customer billing: 0.7% per transaction on Pro, falling with the plan, and its free allowance of 10,500 monthly active users keeps running underneath every paid tier rather than being replaced by it. PropelAuth: Your product is B2B and organisations, roles and per-tenant settings are the hard part rather than the login box. PropelAuth is built around that shape from the start, and it publishes both the per-user rate and the per-connection SSO price, so the bill at a hundred customers is arithmetic rather than a phone call.
StackTab does not sell any of these and has nothing to gain from which one you choose: it scores them. Each case below is the one that option genuinely wins.

Prices and limits move, and a page quoting a stale one is worth less than a page quoting none. Every source is printed here so a reader can check it against the day they are reading this, and a job re-fetches each of these URLs on a schedule and fails when a figure above no longer appears on the page it came from.
