Udibo vs FusionAuth
FusionAuth is a complete authentication server you can run yourself for free or pay FusionAuth to host, with SAML on its free edition and LDAP and SCIM on its paid ones. Udibo is a managed multi-tenant service with organizations, custom roles, and per-resource permissions included on every plan, priced on usage rather than by edition. The difference that decides most evaluations: with FusionAuth you choose a deployment and an edition, and the feature list follows the edition; with Udibo the features are the same on Free and Standard, and the bill follows retained users, hosted permission checks, and email.
Checked September 8, 2026 against FusionAuth's pricing page and license FAQ. Udibo Identity is in private beta, and its prices are a preview, not an adopted rate card.
The short version
| If you need | Start with |
|---|---|
| SAML, LDAP, or SCIM at launch | FusionAuth (SAML on Community, LDAP on Starter, SCIM on Enterprise) |
| A single-tenant deployment you control, self-hosted or hosted for you | FusionAuth |
| Organizations, custom roles, and per-resource permissions with a hosted check | Udibo |
| Sign-in you never operate: no servers, database, backups, or upgrades | Udibo, or FusionAuth Cloud |
| A bill that follows usage instead of an edition ladder | Udibo |
| A production dependency available today without beta access | FusionAuth, until the Udibo hosted service opens to the public |
Why teams pick Udibo over FusionAuth
Nothing to operate. FusionAuth Community is free software, and running it is your job: FusionAuth's own list is database backups, monitoring, networking, upgrades to PostgreSQL and FusionAuth, scaling, load balancing, and proxy configuration (plans and features). FusionAuth will host it for you from $37 a month. Udibo is a hosted service with no deployment to run.
Organizations are a primitive, not a pattern. FusionAuth describes tenants as "collections of users, applications and groups" and models a customer organization from tenants, groups, and entities you compose (organizations). Udibo has organizations with invitations, memberships, and roles on every plan, no cap on organizations or members, and the active organization's id, slug, and roles in the token.
Permissions your server can enforce, on Free. 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. FusionAuth has application roles on every edition; its "Fine-grained Authorization Support" line is on Enterprise.
The same features on every plan. FusionAuth puts email, SMS, and voice MFA methods, breached password detection, the client credentials grant, LDAP, and the self-service account portal on Starter, and SCIM, threat detection, rate limiting, and CAPTCHA on Enterprise. Udibo's Free plan has MFA, organizations, custom roles, hosted checks, audit export, signed webhooks, custom session policy, and your own branding. Udibo does not offer email or SMS MFA, LDAP, or SCIM at all, so read this as a different shape, not a superset.
Growth costs less than a hosted edition. FusionAuth Starter is $162 a month through 10,000 monthly active users and $837 at 100,000. Udibo's preview is $20 and about $290 for the same counts. Self-hosted Community has no per-user price at all; see cost at scale below.
No entity or connector counts. FusionAuth Starter includes 100 machine-to-machine entities and one connector, Essentials 1,000 and five. Udibo has no per-token charge for machine-to-machine tokens (technical and abuse limits apply) and no per-connection fee for OpenID Connect providers.
Why FusionAuth may still be the right choice
Enterprise identity protocols. SAML v2 is on Community, LDAP connectors on Starter, a SCIM server on Enterprise, and passkeys on Community with a free license. Udibo does not offer hosted passkeys, SAML, SCIM, or LDAP today.
A deployment you control. FusionAuth installs from ZIP, DEB, RPM, Docker, or Kubernetes, lists "Run Without Network Access" on every edition, and can be self-run in GovCloud. FusionAuth Cloud gives each customer a separated deployment. Udibo is a multi-tenant hosted service; an open-source identity core is planned for when the hosted service opens, and is not available today.
Customization inside the login transaction. A FusionAuth lambda is a JavaScript function that runs during authentication or authorization and can add claims to a JWT or SAML response (lambdas); lambdas are on every edition, and calling out over HTTP from one is Essentials and above. Udibo's webhooks are asynchronous and cannot replace a synchronous decision.
Free at any user count if you run it. "FusionAuth Community is free and unlimited," and the license FAQ confirms you typically pay nothing to use it for your own application.
Generally available, with paid support. Email ticket support on Essentials, 24/7 phone support and a 99.99% SLA on Enterprise. Udibo Identity is in private beta.
Pricing side by side
FusionAuth's published list and Udibo's pricing preview, same date. FusionAuth prices its hosted editions by monthly active users: anyone who registers, logs in, or opens your app during a calendar month. Udibo prices retained users: a person who returns at least a day after signing up. A signup that never returns counts on FusionAuth and not on Udibo.
| You need | Udibo (preview) | FusionAuth |
|---|---|---|
| Free plan | 500 retained users, 25,000 hosted permission checks, 1,000 emails | Community: "Self-hosted: Free", "free and unlimited"; $37 a month on FusionAuth's basic hosting |
| First paid plan | $5 a month plus usage: 5,000 users, 250,000 checks, 10,000 emails included | Starter, "Starting at: $162/mo", labelled "Billed annually" on the card and "Billed Monthly or Annually" in the plan summary; includes basic hosting |
| Higher editions | One paid plan; no editions | Essentials from $240 a month at 1,000 MAU with business hosting; Enterprise "Contact us" with high-availability hosting |
| Multi-factor authentication | Included on Free (authenticator apps with recovery codes) | TOTP on Community; email, SMS, and voice methods on Starter; per-application MFA policies on Enterprise |
| Custom roles and permissions | Included on Free, across a tenant, an organization, or one resource, with a hosted check | Application roles on every edition; "Fine-grained Authorization Support" on Enterprise |
| Organizations and members | No cap; invitations, memberships, and roles included | Modelled with tenants, groups, and entities; no separate price |
| Remove vendor branding | Included on Free | Theming on every edition; application-specific themes on Starter |
| Enterprise SSO connections | No per-connection fee for OpenID Connect providers; SAML not yet available | SAML v2 and unlimited identity providers on Community; IdP-initiated SAML and LDAP on Starter (1 connector, 5 on Essentials, unlimited on Enterprise); SCIM on Enterprise |
| Audit history | At least 90 days on every plan, exportable as CSV or NDJSON | Audit log on every edition; retention not published on the pricing page |
| Sign-in email | 2 per retained user included, then $1 per 1,000; your own sender is free | Your own SMTP server on every edition; no email price published |
| Users beyond the allowance | $3 per 1,000 retained users | Community: none. Starter: $162 through 10,000 MAU, $312 at 25,000, $462 at 50,000, $687 at 75,000, $837 at 100,000, "Contact us" from 250,000 |
| Hosted permission checks | $10 per 1,000,000 past the allowance | No metered equivalent |
| Machine-to-machine tokens | No per-token charge; technical and abuse limits apply | Client credentials grant and entity management on Starter and above: 100 entities on Starter, 1,000 on Essentials, unlimited on Enterprise |
| Billing cadence | Monthly | "We can bill month-to-month or annually, your choice"; monthly bills on the previous month's actual MAU, annual on an estimate settled at year end |
Three worked examples, with the same assumptions on both sides:
| Scenario | Udibo (preview) | FusionAuth |
|---|---|---|
| Consumer app: 10,000 retained users, 5,000 sign-in emails, MFA on, your own branding | $20 (Standard base plus 5,000 users above allowance) | Community: $0 in software, plus your hosting and operations, or $37 a month on FusionAuth's basic hosting. Starter: $162 a month, hosting included, if you want email or SMS MFA as well as TOTP |
| B2B app: 200 users, 5 organizations of 30 members, custom roles, MFA | $0 on Free, or $5 on Standard | Community: $0 self-hosted plus hosting, or $37 a month hosted; tenants, groups, application roles, and TOTP are yours to configure |
| Consumer app at 100,000 retained users | About $290 | Community: $0 in software plus hosting and operations. Starter: $837 a month at 100,000 MAU |

Cost at scale
Users only, same counts on both sides. Udibo's figures are preview rates; FusionAuth's are what its pricing calculator prints on the date above, for self-hosted Community and for hosted Starter.
| Retained users | Udibo (preview) | FusionAuth Community (self-hosted) | FusionAuth Starter (hosted) |
|---|---|---|---|
| 1,000 | $5 (Standard) | $0 in software; hosting and operations yours | $162 |
| 10,000 | $20 | $0 in software; hosting and operations yours | $162 |
| 100,000 | About $290 | $0 in software; hosting and operations yours | $837 |
| 1,000,000 | About $2,990 | $0 in software; hosting and operations yours | Not published; by quote |
Against Community there is no crossover, because self-hosted software has no per-user price. What you pay instead is the operating list from FusionAuth's own guide, servers, a production database and its backups, monitoring, upgrades, and a proxy, or $37 a month to have FusionAuth run a basic deployment for you. Against Starter, Udibo's preview is lower at every step the calculator prints, and the calculator prints "Contact us" for Starter from 250,000 monthly active users. Keep the metric difference in mind: FusionAuth's count includes first-day signups, Udibo's does not.
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 FusionAuth, you run the server, or FusionAuth Cloud runs a deployment for you, then create a tenant and an application, theme the hosted pages, and use its OAuth 2.0 and OpenID Connect endpoints or SDKs from your app. Lambdas customize claims and behaviour inside the login transaction; webhooks report events after it (FusionAuth documentation, FusionAuth Cloud).
If your integration depends on a synchronous decision during authentication, do not assume a Udibo webhook can replace it. Webhook processing happens outside the original login transaction. 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 LDAP, and its MFA
is authenticator apps with recovery codes, not email or SMS codes. It is a
multi-tenant hosted service with no self-hosted or single-tenant deployment; the
open-source identity core is planned, not shipped. The @udibo/oauth2 package
is a separate option for application-owned authentication, not a self-hosted
edition of the hosted dashboard. Tenant-management calls need administrator
credentials rather than an application's machine token. If a requirement says
identity must run in your own infrastructure, FusionAuth answers it today and
Udibo does not.
Moving an existing FusionAuth application
Inventory tenants, applications, registrations, roles, groups, entities, lambdas, identity providers, and customized themes. Map tenants and groups to your own organization and role records before importing identities; a FusionAuth tenant per customer and a Udibo organization per customer are different shapes, and the token claims your app reads will change with them.
Getting data out: when you self-host, FusionAuth's license FAQ points you at the APIs or the underlying database; on FusionAuth Cloud, a secured database export comes through a support ticket. FusionAuth stores password hashes under named schemes, including bcrypt and PBKDF2-HMAC-SHA256 with base64 salt and hash (password hashes). Udibo's importer reads bcrypt strings and PBKDF2 in an encoded string form, so plan to re-encode from the database columns and test a representative cohort; see user import. MFA enrollment and sessions do not move with account records. Treat webhooks as an integration contract: event names, payloads, retry behaviour, and idempotency may need changes even when the business event sounds identical. See migration planning.
Try next: complete one Udibo login, then give a person two organizations and a different role in each. 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 FusionAuth? If you self-host Community, FusionAuth's software is free at any user count and Udibo is not; what you pay is hosting and the operations work. If you want FusionAuth to run it, Community costs $37 a month and Starter $162 a month through 10,000 monthly active users, against Udibo's preview of $5 at 1,000 users and $20 at 10,000. Past that, Starter is $837 at 100,000 and by quote from 250,000, against about $290 on Udibo.
Does Udibo support SAML, LDAP, or SCIM like FusionAuth? Not today. Udibo connects to any OpenID Connect provider with no per-connection fee; SAML federation, LDAP connectors, SCIM provisioning, and hosted passkeys are not available. FusionAuth has SAML on Community, LDAP on Starter, and SCIM on Enterprise.
Can I move from FusionAuth to Udibo without making users re-register? Profiles and social identities can be imported and linked by the provider's stable subject. Password hashes in a format Udibo's importer reads are upgraded on first sign-in; MFA enrollments and active sessions do not move, so plan a re-enrollment path. See migration planning.
Can I self-host Udibo? Not today. Udibo Identity is a hosted service, and an
open-source identity core is planned for when the hosted service opens. The
@udibo/oauth2 package is a separate option for building OAuth 2.0 and OpenID
Connect into an application you operate, without the hosted dashboard.
