“auth0 / clerk pricing scales horribly”
— r/ChoosingVendors. “Auth0 wants $800/month — too expensive for my 2–3 small enterprise customers” — r/SaaS. Below: what it actually costs, bracket by bracket.
Auth0 cost by MAU, every plan (no SSO)
| MAU | Free | Essentials (B2C) | Professional (B2C) | Essentials (B2B) | Professional (B2B) |
|---|---|---|---|---|---|
| 1,000 | $0 free to 25,000 | $70/mo 1,000 tier · $770/yr | $240/mo 1,000 tier · $2,640/yr | $300/mo 1,000 tier · $3,300/yr | $800/mo 1,000 tier · $8,800/yr |

Monthly USD list price; small print = the Auth0 tier you are billed at and the yearly price (11× monthly). Auth0 sells paid plans only at published MAU tiers and bills usage between tiers at the next tier up, so 25,000 MAU is billed at the 30,000 tier. Where Auth0 goes contact sales: B2C Essentials above 50,000 MAU, B2C Professional above 20,000 (the 30,000 tier is “Contact us”, 40,000+ “Not available”), B2B Essentials above 20,000, B2B Professional above 10,000. Free is the same for B2C and B2B (up to 25,000 MAU, 1 enterprise connection, 5 organizations). Not included: Auth0 for AI Agents, extra M2M tokens, Enterprise MFA on Essentials ($100/mo per auth0.com/pricing.md), taxes and negotiated discounts. Source: auth0.com/pricing.md, checked 2026-10-31.
The Auth0 cost cliff: one more user, the next tier
At 25,000 MAU Auth0 Free is $0. At 25,001 MAU you must be on a paid plan: B2C Essentials $2,100/mo (the 30,000 tier), B2C Professional contact sales (its 30,000 tier is “Contact us”), B2B Essentials and B2B Professional contact sales (their top published tiers are 20,000 and 10,000 MAU).
“At 25k users, you’re paying $300-500/month just for auth” (r/Supabase): on Auth0 it is $0 at exactly 25,000 MAU and $2,100/mo one user later, if Free’s features are enough for you up to then.
Biggest single tier step in Auth0’s self-serve tables: Essentials (B2B) at 10,000 MAU, $2,100/mo → $3,800/mo (+$1,700/mo, +$20,400/yr on monthly billing). Every step:

The SSO cliff: enterprise connections at 5,000 MAU
At 5,000 MAU (assumes 1 customer organization per SSO connection): B2B Essentials is $1,300/mo with its 3 included connections and $1,400/mo with a 4th (+$100); B2B Professional includes 5, so it is $1,500/mo at 5 and $1,600/mo at 6. From 5 connections up both cost the same ($1,600/mo at 6), so Professional’s extra features come at no extra list price there. Auth0 caps both at 30 connections; B2C plans have no enterprise connections, and Free includes 1.
| SSO connections | Free | Essentials (B2C) | Essentials (B2B) | Professional (B2B) |

Monthly USD list price at 5,000 MAU: base tier + $100/mo per connection over the included count (3 on B2B Essentials, 5 on B2B Professional, max 30), from auth0.com/pricing.md.

Cheapest verified plan per vendor, monthly USD list price, no SSO / MFA / SMS. Clerk bills monthly retained users (MRU), never more than your MAU, so these Clerk figures are an upper bound (MAU vs MRU). “No published self-serve price” = the vendor prints no fixed rate at that volume (e.g. Stytch MAU overage). * Logto Pro bills access tokens, not MAU (50k tokens included, then $0.08 per 100) — the figure is base fee only; token overage depends on your usage.
With 3 enterprise SSO customers: At 10k MAU · 3 SSO (assumes 1 customer organization per SSO connection; assumes 200 SSO users per connection for Cognito): Auth0 Essentials (B2B) $2,100/mo; Clerk Pro $275/mo incl. $100/mo B2B Authentication add-on; Stytch Pay as you go (B2B) $0/mo; WorkOS AuthKit $375/mo; Amazon Cognito Lite $8.25/mo. SSO users: Amazon Cognito, Supabase Auth and Firebase Auth / Identity Platform bill SAML/OIDC per SSO user, not per connection (first 50 free, then $0.015 per SSO user a month). Their SSO results here assume 200 SSO users per connection (5 connections = 1,000 SSO users). See how 1,000 or 2,000 per connection changes the result or set your own.
