Auth0 alternative: Faable Auth vs Auth0

Short answer: Auth0 is the reference managed identity platform: OAuth 2.0 and OpenID Connect, a deep feature set and the most complete tooling in the category. It is priced per monthly active user, in tiers, with B2B features on a separate, more expensive price list. Faable Auth is a managed OAuth 2.0 / OpenID Connect identity server in the same category, and it never charges per user. It is free up to 15,000 MAU with no credit card, and Hobby (15 €/month) and Pro (99 €/month) have no MAU limit. It’s operated in Europe by a European company, and it’s the same subscription as your app hosting on Faable Deploy.

At a glance

Pricing, worked through

Auth0 publishes its prices as a table of MAU tiers, and “if your usage falls between tiers, you are billed at the next tier up”.

Monthly prices, as Auth0 lists them. Auth0’s free tier covers the first 25,000 MAU; the table shows what you pay once you need a paid feature such as role management, more Actions or log streaming.

On top of that come the add-ons: more enterprise connections at $100/month each, M2M token packs, and enterprise MFA on B2B Essentials at $100/month. On Faable the plan fee is the bill. The only usage lines are M2M tokens beyond 100 a month (€2.25 per 1,000), enterprise SSO users beyond 50 a month on Pro, and recovery SMS. See Auth pricing.

The reading: under 25,000 users with no paid features, Auth0’s free tier is generous, and more generous than ours at 15,000. Once you need a paid feature or pass 25,000 users, Auth0’s price rises with every tier while Faable’s stays at 15 € or 99 €. The gap is largest for B2B, where Auth0’s separate price list starts at $150/month.

B2B: organizations and enterprise SSO

Auth0’s Free plan includes 5 organizations and 1 enterprise connection. The B2B tiers make organizations unlimited and include 3 (Essentials) or 5 (Professional) enterprise connections, at $100/month for each one above that, up to 30.

On Faable Pro, every customer can be an organization with verified email domains, its own identity provider (Okta, Entra ID, Google Workspace or any OpenID Connect provider) and auto-join for new employees. There’s no per-connection fee: 50 federated users a month are included, and each one above that costs €0.0010. Your tenant can also be the SAML identity provider of your own apps. Auth0 supports SAML in both directions, and Faable doesn’t accept inbound SAML connections yet: if your customers’ identity providers only speak SAML, that matters.

Getting your users out

Leaving any identity provider means taking the password hashes with you, or your users reset their passwords.

• Auth0 exports password hashes and MFA secrets through a support case: Auth0 reviews eligibility (“not all requests qualify”), a second tenant admin must confirm, and an acknowledgment form has to be signed by a CISO, CSO or VP-level executive. The download link expires after three days. Bulk user exports without hashes are self-service, but not on the Free plan.
• Faable Auth imports bcrypt, scrypt, PBKDF2 and Argon2id hashes, and exports them, on every plan, with faable auth users import and faable auth users export --include-hashes. See Import and export password hashes.

Where your users’ data lives

Auth0 lets you choose the region of your tenant, including one in the EU, and it’s part of Okta, a US company. Faable Auth runs in Europe, operated by a European company, with no non-EU region. For SOC 2 or ISO 27001 questions, see our compliance scope.

When Auth0 might fit better

• You need the deepest feature set: adaptive MFA, SMS sign-in, inbound SAML, bot detection and a large integration marketplace.
• You manage identity as code, with Terraform and the Deploy CLI.
• Your company is standardized on Okta, and Auth0 fits that procurement and tooling.
• You stay under 25,000 MAU on free features, where Auth0 costs nothing and gives you more headroom than our Free plan.

When Faable Auth is the better fit

• You’re past Auth0’s free tier, or need one paid feature, and want a bill that doesn’t grow with your users.
• You’re building B2B and don’t want organizations and SSO connections priced as add-ons.
• You want a European company, not just a European region.
• You want auth and hosting together. Faable Deploy and Faable Auth share one subscription.

Migrating from Auth0

The concepts map one to one: Auth0 tenant → Faable account, application → client, API → API, Action → Action. Social connections become Connections with your existing upstream credentials, and users keep their passwords once you have the hash export. The step-by-step version is in Migrate from Auth0.
