Supabase Auth
auth bundled with the database you were already paying for
effectively free auth if you are already paying for the database, under a real mit licence — thin exactly where b2b requirements start.
supabase includes a hundred thousand monthly active users on the $25 pro plan, so the anchor for fifty thousand users is $25 — and that $25 is buying you a postgres database, storage and edge functions as well. on the free plan fifty thousand users is exactly the included allowance, at $0. as a cost line, auth here is close to free for anyone already on the platform.
the server is genuinely open source. the licence file at github.com/supabase/auth is plain mit, so the gotrue-derived auth server can be run independently of supabase's hosted platform, and there is no enterprise carve-out over it.
