Udibo vs Auth0

Auth0 gives you a hosted login page, quickstarts for most application types, custom code inside the login transaction, and a free plan that covers 25,000 monthly active users. Udibo gives you hosted sign-in behind a standard OAuth 2.0 boundary, with organizations, roles, and resource permissions included on every plan. The difference that decides most evaluations: Auth0 lists multi-factor authentication, role-based access control, and more than five organizations from its Essentials plans up and bills by user-count tier, while Udibo includes those controls on Free and charges when you grow.

Checked September 7, 2026 against Auth0's pricing page. This page concerns Auth0 customer identity; for employee identity, see Udibo vs Okta. Udibo Identity is in private beta, and its prices are a preview, not an adopted rate card.

The short version

Why teams pick Udibo over Auth0

• The controls are included, not upsold. Auth0's pricing page lists multi-factor authentication and role-based access control under Essentials, not Free: $35 a month for a consumer app and $150 a month for a business app, each at 500 monthly active users. Both are on Udibo's Free plan, along with a custom session policy and audit export.

• Organizations without a ceiling. Auth0 allows 5 organizations on Free and 10 on its B2C plans; more than that means a B2B plan from $150 a month. Udibo places no cap on organizations or members on any plan, and a person can hold a different role in each.

• Permissions your server can enforce. Udibo lets you register the permissions your application interprets, attach them to roles across a tenant, inside an organization, or on one resource, and read the result from the token or a hosted check. Auth0's pricing page lists role-based access control by plan, per organization on B2C; per-resource checks are not on that page.

• Growth costs less, and the bill does not jump. Auth0 prices by monthly-active-user tier and bills usage between tiers at the next tier up: B2C Essentials is $700 a month at 10,000 users. Udibo's preview is $5 plus $3 per 1,000 retained users past 5,000, so 10,000 users is $20. The meters differ; the pricing section says how.

• Email you can ship with. Auth0's built-in sender is limited to 10 emails a minute and its documentation says it does not support production use, so production needs your own SMTP provider. Udibo includes 1,000 emails on Free and 10,000 on Standard, and a sender you bring is never metered.

• A record you can take with you. At least 90 days of audit history on every Udibo plan, exportable as CSV or NDJSON, against 1 day of log retention on Auth0's Free plan, 5 on Essentials, and 10 on Professional.

• Connections without a meter. Udibo charges no per-connection fee for OpenID Connect providers, though SAML is not yet available. Auth0 includes 3 enterprise connections on B2B Essentials and 5 on B2B Professional, then $100 a month for each additional one.

Why Auth0 may still be the right choice

• 25,000 monthly active users free. If you can ship without multi-factor authentication or role-based access control and inside five organizations, a consumer app on Auth0 pays nothing until it is large. Free also lists passwordless sign-in, unlimited social connections, one custom domain, one enterprise connection, and SCIM.

• Enterprise identity today. Auth0 ships SAML among its enterprise connections, plus SCIM and custom domains, with one of each on Free. Udibo does not offer SAML, SCIM, hosted passkeys, or dashboard-driven custom domains today.

• Code inside the login transaction. Auth0 Actions are versioned Node.js functions that run at points such as post-login and pre-user-registration. Udibo's webhooks are signed and retried, but asynchronous; they are not a replacement for logic that must run before a login completes.

• Breadth of quickstarts. Auth0 documents quickstarts for single-page, regular web, native, and backend applications. Udibo's guides cover the authorization-code flow, organizations, and permissions.

• Generally available. Auth0 is a production dependency you can adopt this afternoon. Udibo Identity is in private beta.

Pricing side by side

Auth0's published list and Udibo's pricing preview, same date. The meters differ. Auth0 counts a monthly active user as "any non-internal (non-employee) user that authenticated during a given month for a given tenant"; Udibo counts a retained user, "a person who returns more than 24 hours after signing up". Auth0 bills usage between tiers at the next tier up, and its published tiers end at 50,000 users on B2C Essentials, 30,000 on B2B Essentials, and 20,000 on B2B Professional; above those, the page says to contact sales.

Three worked examples, with the same assumptions on both sides: every user signs in during the month and returns after their first day, so both meters agree.

Sources: Auth0 pricing, Auth0 SMTP email providers, and Udibo's pricing preview. Both change; check the vendor's current page before you decide.

Cost at scale

Users only, same definition on both sides, on the plan that gives you MFA and your own branding. Udibo's figures are preview rates; the vendor's are its published list on the date above.

Auth0's Free plan is $0 to 25,000 monthly active users with five organizations and no MFA line. The moment a product needs MFA or role-based access control it moves to Essentials, which is billed by user-count tier and rounds up to the next tier.

What the integration looks like

With Udibo, register an application and its callback, send people to the hosted sign-in page, and finish the authorization-code flow on your server. Your backend holds the session and the browser gets a cookie, never a token. The first-login guide walks each checkpoint, and the organizations and permissions guides cover a person with a different role in each of two organizations.

With Auth0, Universal Login is the hosted login page, quickstarts are grouped by application type, and Actions attach versioned functions to authentication and lifecycle triggers (Auth0 quickstarts, Universal Login experience, Actions overview). Both products hand you a hosted page and an OpenID Connect authorization-code flow, so the server-side wiring has the same shape: issuer, client, callback, token validation.

Neither approach removes your responsibility to protect application data on the server. A valid session says who someone is; your backend still decides what they may read.

Where Udibo needs a closer look

Udibo does not currently offer hosted passkeys, SAML, SCIM, or dashboard-driven custom domains. There is no equivalent of Actions: webhooks are asynchronous, so code that must accept or reject a login inline belongs in your own application. Udibo hosts the sign-in pages and returns to your app; the account screens inside your product are yours to build. Tenant-management calls need administrator credentials rather than an application's machine token. The @udibo/oauth2 package is a separate option for application-owned authentication, not the hosted service. An open-source identity core is planned under the MIT license for when the hosted service opens; it is not available today. Test the whole journey your product depends on before committing; a successful login alone does not establish parity.

Moving an existing Auth0 application

List your connections, Actions, custom claims, organization rules, callback URLs, and application APIs, and separate identity work from business logic so you can decide where each behavior belongs afterwards. Test token validation against both issuer and audience; changing a domain string alone is insufficient. Give your own user records stable IDs and record the mapping from the old issuer and subject to the new one; do not use email alone as an automatic account-linking rule. Password hashes, MFA enrollment, and sessions do not move with a profile, so plan a re-enrollment path, and re-test every Action-dependent denial path against the server-side rule that replaces it. See migration planning and user import.

Try next: complete one Udibo login, then reproduce your most demanding authorization rule before moving users. If you are on the waitlist, the agent integration brief lets your coding assistant prepare the integration in the meantime.

Frequently asked questions

Is Udibo cheaper than Auth0? For an app that can live inside Auth0's Free plan, no. For an app that needs MFA, role-based access control, or more than five organizations, Auth0 starts at $35 a month for 500 users and $700 at 10,000, where Udibo's preview is $0 on Free and $20 on Standard.

Does Udibo have something like Auth0 Actions? Not as code that runs inside the login transaction. Udibo delivers signed webhooks after the fact, with retries and redrive, and lets you shape what a token carries through the organization claims and your own permission vocabulary.

Can I move from Auth0 to Udibo without making users re-register? Auth0 can export user profiles and, on request, password hashes. Udibo imports profiles and supported hashes with an upgrade on first sign-in, and links social identities by the provider's subject. MFA enrollments and sessions do not move. See migration planning and user import.

Does Udibo support SAML or SCIM like Auth0? Not today. Udibo connects to any OpenID Connect provider with no per-connection fee; SAML, SCIM, and hosted passkeys are not available.
