Best Clerk alternatives in 2026
These are the 2 closest tools to Clerk that we track, ordered by what they cost to start. Each entry says how its pricing differs from Clerk's — based on the numbers we hold, not on who pays us. We do not publish a quality score, because we do not have one we can stand behind.
Of the 2 alternatives on this page, 1 publish a price we could verify. The cheapest paid step among them is Auth0 at $35/mo, while Clerk starts paid at $25/user/mo billed annually. Auth0 publishes a free plan.
